Kaylynn Blue had not shown up for work.

The 33-year-old worked at Walgreens in eastern Idaho, and her absence immediately seemed unusual to people who knew her. Blue's sister later explained that missing work without calling simply was not something Kaylynn normally did. Coworkers became worried, contacted her family, and the concern eventually reached police. East Idaho News

On June 24, 2019, Idaho Falls police went to the home where Blue lived with her longtime boyfriend, Philip Michael Schwab.

The officers were there to check on her welfare.

They would leave investigating a homicide.

Inside the residence, officers noticed blood. Schwab was questioned. According to the probable-cause material later reported by local news outlets, he admitted that he had hurt Blue and directed officers toward the backyard.

Investigators found Blue partially buried in a shallow grave in a flowerbed.

Police also discovered the bodies of two dogs in the garage.

What had begun as concern over an employee who had unexpectedly missed work became one of the most disturbing homicide investigations Idaho Falls police had encountered. Police Chief Bryce Johnson described the case at the time as an extraordinarily violent crime and said officers realized quickly that the welfare check was something much more serious. Local News 8

The investigation did not end with an allegation.

Nearly two years later, Schwab pleaded guilty to first-degree murder. On June 30, 2021, District Judge Bruce Pickett sentenced him to a minimum of 25 years in prison and up to life. East Idaho News

Behind that legal outcome, however, was a family that had gone from wondering why someone had missed work to learning that their loved one would never come home.

The First Warning Was Something Small

There was no dramatic beginning to the investigation.

No officer arrived expecting to uncover a grave.

Instead, Blue simply failed to appear at work.

That detail became important because her absence was so inconsistent with her routine. Blue's sister, Brittany Kochar, told East Idaho News that her sister was dedicated to her job and would normally call if something prevented her from working.

Blue had previously worked at Walgreens in Denver before transferring to an eastern Idaho location after moving. Her family said she enjoyed the job and the people around her. East Idaho News

When she failed to report for work and did not call, coworkers became concerned.

They reached out.

Family members also tried contacting her.

Nothing reassured them.

Blue's sister called Schwab and asked what was happening. According to her account to East Idaho News, Schwab said Blue was missing, even though her vehicle was still at the residence. His response only added to the family's concern. East Idaho News

Eventually, police were asked to check on Blue.

Local reporting indicates Idaho Falls police received the welfare-check request at about 9 a.m. on June 24. Officers went to the Thayer Bridge area, near Tautphaus Park, expecting to determine why Blue had disappeared from her normal routine. Local News 8

That seemingly ordinary call became the doorway into everything that followed.

Officers Enter the Home

Schwab was at the residence when officers arrived.

Police entered and quickly noticed something that made an ordinary explanation increasingly difficult.

There was blood inside the home.

Chief Johnson later said officers realized very quickly that they were dealing with more than a standard welfare check. Local News 8

That moment is critical to understanding the investigation.

Police did not arrive knowing that Blue was dead.

They were initially trying to determine whether she was safe.

Once officers encountered evidence suggesting violence, however, their priorities changed.

The residence could now be a crime scene.

Schwab could possess information about Blue's disappearance.

And investigators had to determine whether something violent had happened before they arrived.

According to court documents later summarized by East Idaho News, Schwab ultimately told police where Blue was.

The answer was outside.

The Backyard Revealed the Truth

Officers went toward the backyard.

There, investigators observed what appeared to be a recently disturbed area of soil.

Blue had been placed in a shallow grave.

Court documents described a scene in which portions of her body remained visible above the dirt when police found her. East Idaho News

At that point, there was no longer a missing-person mystery.

Police had found Blue.

But finding her answered only one question.

Investigators now needed to determine precisely what had happened inside the house, how Blue had died, when she had been killed, what Schwab had done afterward, and whether his statements were consistent with the physical evidence.

The property was secured.

Police worked to obtain the necessary search authority while investigators began treating the residence and surrounding property as a homicide scene. Local reporting from the day of the discovery described police cordoning off the area as they waited for search warrants covering the house and yard. Local News 8

For neighbors, the scene would have been unmistakable.

Police vehicles.

Restricted access.

Investigators moving through a normally residential area.

And eventually, personnel carefully working around the backyard where Blue had been concealed.

Recovering a Body Is Also Evidence Collection

Images of responders digging can make the process appear straightforward.

It is not.

When a body has been concealed in soil, the location itself can become evidence.

Investigators cannot treat the area like an ordinary excavation.

The position of the remains matters.

The depth of the grave can matter.

The condition of the surrounding soil may matter.

Objects near the body may matter.

Investigators need to document what they find before disturbing it unnecessarily.

That careful process helps explain why scenes like the one captured in the thumbnail can involve multiple personnel working methodically rather than simply removing the remains immediately.

In Blue's case, the backyard would become an important part of reconstructing what Schwab did after killing her.

According to the probable-cause documents, Schwab told detectives that he had used water to soften the ground before digging. He then moved Blue outside and attempted to conceal her in the flowerbed. East Idaho News

The grave was not deep enough to completely hide her.

Police found her the following day.

Investigators Reconstruct the Attack

What happened before the burial emerged through Schwab's interviews with detectives and the evidence police documented inside the residence.

The details initially appeared in probable-cause documents, meaning they were part of the state's account at the beginning of the criminal case. Schwab later pleaded guilty to first-degree murder, establishing his criminal responsibility for Blue's death. East Idaho News

According to those court documents, Schwab told investigators that he and Blue were in bed early on June 23.

He claimed that Blue was moving while asleep and accidentally striking him.

Schwab said he got out of bed and retrieved a knife he had previously placed in a dresser.

He then attacked Blue.

Blue woke and tried to get away.

According to the account Schwab gave detectives, she moved from the bedroom toward other areas of the home while attempting to escape, but the attack continued. East Idaho News

The later sentencing record established the severity of what happened. The Idaho State Journal reported that Blue had been stabbed 25 times. Idaho State Journal

Afterward, Schwab attempted to conceal her body outside.

The sequence gave investigators a path to reconstruct.

The bedroom.

The hallway and other areas through which Blue attempted to escape.

The backyard.

The grave.

Physical evidence collected from those locations could be compared with what Schwab had told detectives.

Two Dogs Were Also Found Dead

Investigators encountered another disturbing discovery inside the property.

Two dogs were dead in the garage.

Police reported that the animals had also been stabbed. East Idaho News

The discovery expanded the crime scene.

Investigators were no longer dealing only with the locations associated with Blue's killing and burial.

The garage also required examination.

Every additional location meant more evidence to document, photograph and preserve.

For officers who had arrived expecting a welfare check, the transformation could hardly have been more extreme.

They began with one question:

Where is Kaylynn Blue?

Within hours, they had a homicide scene encompassing multiple areas of the property.

The Family Was Already Afraid Before Police Confirmed the Worst

Blue's relatives did not need to see the crime scene to understand that something was wrong.

Her silence was enough.

Her sister's account makes clear why.

Blue stayed in contact.

She was dependable about work.

She did not simply disappear without communicating.

When those patterns suddenly changed, her family recognized the significance.

The phone conversation with Schwab increased the uncertainty rather than resolving it. Blue's car was reportedly still at the home, yet Schwab told her sister he did not know where she was. East Idaho News

Hours later, the family received confirmation from police.

Blue was dead.

The disappearance they hoped would have a harmless explanation had become permanent.

That sequence is part of what makes the case particularly haunting.

The warning signs were not initially dramatic.

They were ordinary disruptions in routine.

A missed shift.

An unanswered phone.

A loved one who suddenly stopped responding.

People close to Blue noticed because they knew her habits.

Their concern was ultimately what brought police to the house.

Remembering Kaylynn Beyond the Crime Scene

A homicide investigation inevitably concentrates attention on the offender and the circumstances of the crime.

Blue's family wanted people to understand that her life was much larger than what happened in the final hours.

She was 33.

She had moved from Colorado to Idaho.

She worked at Walgreens and, according to her sister, loved her job and the people she worked with. East Idaho News

Her sister described her as an extraordinarily kind and innocent person.

Years later, during Schwab's sentencing, Blue's brother Tristan also described the qualities his sister brought into the lives of others. He told the judge that she radiated positivity, love and compassion and treated people with kindness. Idaho State Journal

Those descriptions provide necessary context.

Crime stories can reduce a victim to a photograph beside a headline.

But Blue was someone's sister.

She was a coworker whose absence mattered enough for people at Walgreens to become alarmed.

She had routines.

She sent messages.

She maintained relationships.

Those relationships ultimately ensured that her unexplained disappearance did not go unnoticed.

Digital Activity Became Part of the Investigation

Police also examined Schwab's online activity.

Court reporting described hundreds of unusual Facebook posts made around the period of the killing, including posts that prosecutors later referenced during the case. At sentencing, the prosecutor cited one particularly disturbing post involving stabbing. Idaho State Journal

Digital evidence must always be interpreted in context.

A social-media post by itself does not establish that someone committed a crime.

People write disturbing, fictional, sarcastic or irrational things online every day.

But when investigators already have a homicide, a defendant's statements, physical evidence and a detailed timeline, online activity can become another piece of that timeline.

In this case, prosecutors did not have to rely solely on social-media material.

Police had found Blue's body on the property.

They had evidence inside the residence.

They had Schwab's statements.

And eventually they had his guilty plea.

Schwab Was Arrested

Police arrested Schwab on June 24, the same day Blue's body was discovered.

He was booked into the Bonneville County Jail and charged with first-degree murder.

At his first court appearance, the case had not yet reached anything resembling a final judgment.

That distinction matters.

In June 2019, Schwab was an accused defendant.

Although police said he had admitted killing Blue during interviews, he still had constitutional rights and the criminal case still had to proceed through court.

Local reporting indicates he was initially held without bond. Local News 8

The prosecution then began the process of moving a first-degree murder case through Idaho's court system.

The Legal Case Did Not Move in a Straight Line

One reason it is important to follow criminal cases beyond the arrest is that the initial police encounter rarely tells the complete legal story.

In October 2019, Schwab waived his preliminary hearing.

A preliminary hearing would ordinarily require prosecutors to present enough evidence for a judge to determine whether the case should proceed. By waiving it, Schwab allowed the murder charge to advance directly to district court. East Idaho News

At his November arraignment, Schwab pleaded not guilty to first-degree murder. East Idaho News

That meant the case was formally contested.

At the time, it would have been inaccurate for a news report to call him a convicted murderer.

He had been charged.

He had entered a not-guilty plea.

The prosecution still had to resolve the case through trial or another lawful disposition.

Prosecutors Decide Against Seeking the Death Penalty

First-degree murder made Schwab potentially eligible for Idaho's most serious penalties.

However, the Bonneville County Prosecutor's Office ultimately announced that it would not pursue the death penalty.

The decision reflected both aggravating and mitigating factors.

Prosecutors described the evidence as overwhelming and identified the nature of the killing as an aggravating consideration. But court documents also discussed Schwab's developmental disability, lack of prior criminal conduct and other mitigating information. East Idaho News

The decision is important because sentencing decisions in serious criminal cases are rarely based on a single fact.

Prosecutors must consider the offense, available evidence, applicable statutes and information relevant to punishment.

Taking capital punishment off the table did not reduce the seriousness of the first-degree murder charge.

Schwab still faced the possibility of spending the rest of his life in prison.

Questions About Schwab's Ability to Understand the Proceedings

The defense also raised concerns about Schwab's ability to understand the legal process.

Court documents reported by East Idaho News said he had been diagnosed with 22q11.2 deletion syndrome, also known as DiGeorge syndrome, and experienced developmental difficulties. His attorneys sought accommodations that would help him understand what was happening in court. East Idaho News

This information requires careful handling.

A developmental or medical condition does not automatically establish why someone committed a crime.

Nor should a diagnosis be used as a general explanation for violent behavior.

In Schwab's case, the condition became relevant to his legal proceedings and later sentencing arguments because attorneys and the court had to consider his ability to understand the process and the mitigating evidence presented on his behalf.

It did not erase criminal responsibility.

Schwab would eventually plead guilty.

The Case Remained Open for Nearly Two Years

By June 2020, one year after Blue's death, Schwab remained in the Bonneville County Jail awaiting resolution of the murder charge.

Local reporting revisited the case on the anniversary and summarized the evidence prosecutors had accumulated. East Idaho News

For Blue's family, that meant the discovery in the backyard had not brought immediate legal closure.

Criminal proceedings take time.

Attorneys investigate.

Experts evaluate evidence.

Motions are filed.

Competency and sentencing issues may require additional consideration.

Court schedules change.

The difference between the speed of a police video and the speed of the justice system can be enormous.

The body-camera portion of the story unfolds over hours.

The criminal case unfolded over years.

A Guilty Plea Finally Changes the Legal Status

On April 20, 2021, the case reached a decisive moment.

Schwab appeared before District Judge Bruce Pickett and pleaded guilty to first-degree murder.

He admitted murdering Kaylynn Blue on June 23, 2019. East Idaho News

From that point forward, the terminology changed.

Schwab was no longer merely a man accused by police of killing his girlfriend.

He had admitted guilt in court.

That distinction is essential when discussing older body-camera footage today.

The footage shows officers investigating an apparent crime before a conviction existed.

Contemporary reports from June 2019 appropriately used terms such as “accused” and “charged.”

A retrospective account can now include the subsequent guilty plea and sentence.

This allows the complete legal timeline to be told without treating early allegations as though they were already proven when officers first arrived.

The Sentencing Hearing Brings the Family Back Into the Story

On June 30, 2021, Schwab returned to court for sentencing.

Prosecutors recommended that he serve at least 25 years before becoming eligible for release.

The defense argued for a 15-year minimum.

Judge Pickett ultimately imposed a sentence of 25 years to life for first-degree murder. Schwab was also ordered to pay fines. Idaho State Journal

The hearing was not simply about numbers.

Blue's family had the opportunity to explain what her death had done to them.

Her brother Tristan delivered a victim-impact statement.

He described Blue as loving and compassionate. He also explained how quickly the family knew something was wrong when she stopped answering them because she normally stayed in contact.

He recalled learning about her death while traveling home.

The family, he said, had experienced the kind of nightmare people hope will never become their reality. Idaho State Journal

A Question the Court Could Not Answer

One issue remained unresolved even after Schwab admitted killing Blue.

Why?

Judge Pickett addressed that uncertainty at sentencing.

Despite the extensive police investigation, Schwab's detailed account and the evidence gathered from the home, the court was still left without a satisfying explanation for what motivated the killing.

The judge indicated that a complete answer might never be known. Idaho State Journal

That uncertainty is important.

True-crime storytelling often tries to provide a clean motive because audiences naturally want events to make sense.

Real cases do not always provide one.

Investigators can establish what happened without being able to explain every psychological reason behind it.

A responsible account should not invent a motive simply because the absence of one feels incomplete.

The Sentence Does Not Mean Release After 25 Years

The phrase “25 years to life” can also be misunderstood.

The sentence did not mean Schwab would automatically leave prison after exactly 25 years.

It established a minimum period of incarceration before the possibility of release under the applicable system.

The maximum sentence is life.

That distinction matters when describing the outcome.

It is more accurate to say Schwab received a sentence of 25 years to life than to say he was sentenced to only 25 years.

The court chose that punishment after considering the crime, mitigation presented by the defense, the prosecution's arguments and the impact on Blue's family. Idaho State Journal

Why the Welfare Check Matters So Much

The most remarkable part of this case may be how little information officers had at the beginning.

A woman had not gone to work.

Her coworkers were concerned.

Her family could not reach her.

That was enough to prompt a welfare check.

It was also enough to uncover a homicide.

Welfare checks are easy to overlook because many end without an arrest or dramatic discovery.

Officers may locate someone who is perfectly safe.

They may discover that a phone has been lost or turned off.

They may find someone who needs medical assistance.

Sometimes there is no emergency at all.

But officers do not know which situation awaits them until they investigate.

Blue's case demonstrates the most serious possible version of that uncertainty.

The call sounded routine.

The scene was anything but routine.

Coworkers Played a Quiet but Crucial Role

It is also worth returning to the people who first noticed something was wrong.

Blue's coworkers.

Their role was not dramatic enough for a crime-scene thumbnail.

They did not arrest Schwab.

They did not excavate the backyard.

They did not prosecute the murder.

But they noticed Blue was missing.

That observation started the chain that brought authorities to the residence.

The case illustrates the value of knowing someone's normal behavior.

A missed shift means little in isolation.

For someone known to be reliable and communicative, repeated unexplained absence can be significant.

Blue's coworkers did not know what had happened.

They simply knew that what was happening was not normal for her.

They acted on that concern.

The House Told Investigators What Words Could Not

When police arrived, they had to evaluate more than Schwab's explanation.

They had the physical environment.

Blood inside the residence immediately contradicted the possibility that nothing serious had occurred.

The backyard provided another piece.

The garage provided another.

Schwab's statements could then be compared against those locations.

This is a fundamental part of criminal investigation.

People can lie.

People can be confused.

People can minimize what happened.

Physical evidence does not provide a complete narrative by itself, but it can support or undermine what someone says.

In Blue's case, detectives reported finding evidence consistent with portions of Schwab's account. East Idaho News

The scene and the statements converged.

The Backyard Scene Is Only One Part of the Story

The thumbnail naturally focuses attention on investigators digging.

It is visually powerful.

But concentrating only on that moment risks reducing the case to its most disturbing image.

The story actually stretches across several years.

It begins with Blue's life and routine.

Then comes the unexplained absence.

The welfare check.

The blood.

Schwab's statements.

The backyard.

The arrest.

The court proceedings.

The initial not-guilty plea.

The decision not to pursue capital punishment.

The eventual guilty plea.

The sentencing hearing.

And finally, the family's attempt to describe the person they lost.

Each stage adds context the excavation image cannot provide.

A Crime Scene Eventually Becomes a Court Record

Body-camera footage freezes investigators at the beginning of the legal process.

The officers do not know everything yet.

They cannot know what plea will be entered two years later.

They do not know what sentence a judge will impose.

They are dealing with the immediate scene.

Looking back now allows the police footage to be connected to the full court record.

Schwab was charged with first-degree murder.

He initially pleaded not guilty.

Prosecutors declined to seek the death penalty.

He later changed his plea and admitted the murder.

Judge Pickett sentenced him to 25 years to life. East Idaho News

That progression matters because each term represents a different legal stage.

Accuracy requires preserving those differences.

Kaylynn Blue Is More Than the Final Moments of Her Life

Perhaps the most important corrective to crime-scene coverage is remembering the victim outside the crime.

Blue's relatives described someone who was kind, dependable and connected to the people around her.

Her work mattered to her.

Her coworkers noticed when she disappeared.

Her family immediately recognized that silence was abnormal.

Her brother kept voicemail messages from her.

At sentencing, those recordings became reminders of a life that existed before the homicide investigation. Idaho State Journal

A grave is where police found Blue.

It is not what defined her.

The legal case understandably focuses on the crime because courts must determine responsibility and punishment.

Her family's memories provide the rest of the picture.

From Concern to Discovery to Justice

The entire case can be traced back to one simple observation.

Kaylynn Blue was not where she was supposed to be.

Someone noticed.

Then someone called.

Police went to the house.

Inside, they found evidence that changed the direction of the call.

Outside, they found Blue.

Investigators documented the scene and arrested Schwab.

Prosecutors filed a first-degree murder charge.

For nearly two years, the case moved through the courts.

Then Schwab admitted guilt.

Finally, a judge sentenced him to 25 years to life.

There is no need to add invented details to make that sequence dramatic.

The verified record is already devastating.

The Lasting Meaning of the Welfare Check

When Idaho Falls officers approached the home on June 24, 2019, they were responding to uncertainty.

Blue might have been ill.

She might have gone somewhere without telling anyone.

There could have been a harmless explanation.

Her coworkers and family simply wanted to know that she was safe.

Instead, officers found blood.

Then they learned where to look outside.

The shallow grave ended the search for a missing woman and began the search for evidence.

For Blue's family, the discovery confirmed the fear that had grown with every unanswered call.

For police, it turned a welfare check into a homicide investigation.

For prosecutors, it became a first-degree murder case.

And for Schwab, it eventually resulted in a guilty plea and a sentence of 25 years to life.

Yet the case should not end with him.

The reason police were there at all was that people cared about Kaylynn Blue.

Her absence mattered.

Her silence mattered.

The fact that she failed to appear at Walgreens mattered because the people around her knew it was unlike her.

That concern could not save her.

But it prevented her disappearance from remaining unexplained.

It brought police to the place where she had been concealed.

It allowed investigators to recover her, document what happened and build the case that ultimately ended with an admission of guilt.

The image of investigators carefully working through the sandy ground may be the moment that attracts attention years later.

Behind that image is a much larger story.

A sister who knew something was wrong.

Coworkers who refused to ignore an unexplained absence.

Officers who recognized that the evidence inside the house did not fit an ordinary welfare check.

Detectives who reconstructed what happened.

A family that waited through nearly two years of criminal proceedings.

And finally, a courtroom where the man responsible admitted that he had murdered Kaylynn Blue.

That is what transformed a missed shift at work into a homicide investigation and, eventually, a first-degree murder conviction.

It is also why the most important fact about this case is not simply where police found Kaylynn Blue.

It is that people noticed she was gone.

They went looking for her.

And when the truth was finally uncovered, the criminal justice process established responsibility for what happened.

Watch the full police encounter to see how a routine welfare check develops into the discovery that changed the investigation completely.
