CBS’s 48 Hours presents “A Death in the Stairwell” on Saturday, August 29, 2026, at 10/9c, with correspondent Peter Van Sant examining the death of Kevin Davis and the murder prosecution that followed against his wife, Alison Davis.
The case began inside the couple’s Indiana home on August 12, 2023. Alison said she woke after hearing a loud noise and found Kevin face down at the bottom of the stairs in a pool of blood. Her immediate explanation was that her husband had fallen.
The police detective who entered the house that morning came to the same conclusion. The scene appeared consistent with an accident, and Alison’s account seemed to fit what he saw.
Kevin died from his injuries the following day.
Four months later, the same detective reached a different conclusion. Authorities charged Alison with murdering her husband, arguing that Kevin’s head injuries were not the result of an accidental fall but of a violent assault.
No murder weapon was found.
The prosecution nevertheless took Alison to trial after she spent 17 months behind bars. The jury needed about six hours to decide the case.
Alison Davis was found not guilty.
“A Death in the Stairwell” examines how a death first treated as an accident became a murder case, why investigators changed their minds, the role of medical evidence, a bedroom police did not search because of the couple’s dog, and the weaknesses jurors later identified in the prosecution’s theory.

- Who Was Kevin Davis & What Happened to Him? 2026 Update & Profile
Kevin and Alison Davis Were Described as a Loving Couple
Friends and relatives described Kevin and Alison Davis as a couple who appeared happy together.
Alison’s father, Steve Krause, said the two called each other “babe.” Alison’s best friend, Kasey Klemm, remembered them dancing together in the kitchen.
There were no children in the marriage.
Instead, the couple shared a close attachment to their dog, Willow, a black-and-white pit bull mix whom Alison’s father described as being like a child to them.
Willow would become an unexpected part of the criminal investigation.
The dog was protective of the house and could appear intimidating to people she did not know. A friend of the couple described her as a loud barker who settled once she became familiar with someone.
That characteristic would matter on the morning police entered the Davis home.
Kevin and Alison Went to a Tavern on the Night Before His Death
On the night before Kevin was found injured, he and Alison went together to a local tavern.
People who saw them there did not report seeing a couple in the middle of a serious confrontation.
Friends and tavern employees described the evening as typical and said Kevin and Alison appeared happy when they left.
They returned home at about 1 a.m.
According to Alison, an argument began after they arrived.
The existence of that argument would become important after investigators began treating Kevin’s death as a possible homicide.
Alison did not deny that she and Kevin had argued.
She said the disagreement ended with the couple sleeping in different parts of the house.
Alison Said She Slept Downstairs After the Argument
Alison told police that after the argument she chose to sleep on a couch downstairs.
Kevin went upstairs to their bedroom.
Willow was upstairs with him.
Alison said she later woke to a loud noise.
She went to investigate and found Kevin at the bottom of the stairwell.
He was lying face down.
There was a large amount of blood.
Alison called 911 and told the dispatcher that her husband had fallen down the stairs.
That explanation remained her position from the first emergency call through the murder investigation and the trial that followed.
Kevin Davis Was Found With Severe Head Injuries
Emergency responders arrived and found Kevin critically injured.
The extent of his head trauma made clear that he had suffered a catastrophic event.
He was rushed to a hospital.
Kevin survived for less than another day.
His death transformed what might otherwise have remained an investigation into a household accident into a case requiring a close examination of the circumstances surrounding the fall.
Police needed to determine whether the staircase itself could account for Kevin’s injuries.
At first, the answer appeared to be yes.
Detective James Krueger Initially Believed Kevin Had Fallen
Detective James Krueger of the New Haven Police Department questioned Alison after Kevin was transported to the hospital.
Alison signed paperwork allowing police to enter and search the couple’s home.
She did not attempt to prevent investigators from going inside.
She did, however, warn Krueger about Willow.
Alison said the dog was protective and told police she did not know how Willow might react to strangers entering the bedroom.
She also expressed concern that something could happen to the dog.
Krueger entered the home and examined the scene.
What he saw did not cause him to reject Alison’s explanation.
His first conclusion was that the circumstances appeared to support a tragic accident.
Willow Prevented Police From Entering One Bedroom
The upstairs bedroom became one of the most controversial aspects of the investigation.
Krueger could hear Willow moving inside the room.
He opened the door enough to assess the dog.
Willow responded with teeth and growling.
Krueger decided not to enter.
He later said there was no way the dog was going to allow him into the room.
Police searched the rest of the house but did not conduct the same examination of the bedroom where Willow had been confined.
At that stage, the omission did not appear significant.
Krueger believed Alison’s account.
Years later, after Alison had been acquitted, he would return to that unopened room as one of the unanswered questions in the case.
The Initial Investigation Supported the Accident Theory
After looking through the house, Krueger believed the evidence supported Alison’s statement that Kevin had fallen.
The physical scene did not cause him to accuse Alison of an assault.
He later recalled feeling that everything “checked out.”
That first reaction became important when the case reached trial.
The same officer who later developed the theory that Alison had beaten Kevin to death had begun the investigation believing that she was telling the truth.
The shift did not occur because police found a murder weapon inside the home.
They never did.
It came after investigators and medical experts began taking a different view of Kevin’s injuries.
Kevin Died the Day After He Was Found
Kevin’s injuries proved fatal.
He did not survive another day.
His death devastated Alison, according to her family and friends.
People who knew the couple described her as grieving the loss of a husband she loved.
At that point, there was no murder charge.
The case had begun as what police themselves considered a fatal accident.
But the medical examination of Kevin’s injuries raised questions.
The autopsy became the foundation for a different theory.
Instead of Kevin falling and striking his head, investigators began considering whether someone had struck Kevin before he was found at the bottom of the stairs.
The Autopsy Changed the Direction of the Investigation
The medical evidence became the central dispute in the case.
Authorities concluded that Kevin had suffered massive traumatic injuries to his head.
The question was how those injuries had occurred.
An accidental fall down a staircase can produce severe trauma. A person can strike steps, walls, railings and the floor during a fall.
But investigators came to believe Kevin’s particular injuries did not fit that explanation.
The prosecution theory developed around the idea that the trauma was caused by blunt-force blows.
That interpretation moved the investigation away from accidental death and toward homicide.
If Kevin had been struck with an object, investigators needed to determine who could have attacked him inside the home.
Their focus turned to Alison.
Investigators Began To Suspect Alison Had Beaten Kevin
Four months after Kevin’s death, police arrested Alison Davis.
Detective Krueger had changed his assessment of the case.
He came to believe that Alison had lost control during or after the couple’s argument and attacked Kevin.
Krueger later summarized the police theory as a wife who “lost it” and beat her husband to death.
Authorities believed an improvised blunt-force weapon could have been used.
Possible objects included an exercise weight or a baseball bat.
There was a major problem with that theory.
Police did not have the weapon.
No object was recovered and proved to have been used to kill Kevin.
Prosecutors Had To Explain How Kevin Ended Up at the Bottom of the Stairs
Once investigators rejected an accidental fall, they had to develop another explanation for the scene.
The prosecution argued that Kevin had suffered injuries caused by an assault rather than a simple tumble down the staircase.
That meant the location of his body could not be treated as conclusive proof of an accident.
The stairs might have been part of the assault or the final location where Kevin came to rest.
For the defense, the same scene supported Alison’s account.
Kevin had been found where a person who fell from the upper floor might be expected to end up.
The case therefore became a battle between physical possibility and medical interpretation.
Could the staircase explain the injuries?
Or were the injuries evidence that Kevin had been beaten?
There Was No Witness to an Attack
No one testified to seeing Alison strike Kevin.
There was no eyewitness who described a fight that turned violent.
The prosecution had to build its case from circumstantial and forensic evidence.
That placed heavy importance on the couple’s argument, the autopsy findings, the condition of the home and Alison’s account of where she had been sleeping.
The defense could point to another significant fact.
Alison had called for help.
She had also consented to the police search.
Her explanation that Kevin had fallen was not something she developed after learning that she was under suspicion.
She gave that account from the beginning.
No Murder Weapon Was Ever Found
The missing weapon became one of the weaknesses in the state’s case.
Authorities suggested several objects that could have produced blunt-force injuries.
They could not identify a specific object that had been used.
No exercise weight was established as the weapon.
No baseball bat was established as the weapon.
No blood-covered object was recovered and linked through forensic evidence to an assault on Kevin.
Prosecutors therefore asked jurors to accept that Kevin had been beaten without presenting the object used to beat him.
The absence of a weapon did not make prosecution impossible.
But in a case built around the theory of a violent beating, it created another question the state had to overcome.
Police Later Wondered Whether Willow Had Protected the Murder Weapon
After Alison’s acquittal, Krueger returned to the bedroom he had not searched during the first investigation.
He wondered whether Willow had prevented police from finding crucial evidence.
Krueger suggested that Alison might have put the dog in the bedroom to keep investigators out.
Under that theory, a blunt-force weapon could have been inside.
He acknowledged that the possibility remained speculation.
Police never searched the room that morning, so no evidence established that a weapon had been there.
The theory became one of the most striking elements of the case because it turned the couple’s dog into part of the debate over the investigation.
Was Willow simply behaving like the protective dog Alison had warned police about?
Or had the dog’s presence prevented investigators from finding something important?
The trial produced no proof that the bedroom contained a murder weapon.
Alison Davis Spent 17 Months Behind Bars
The murder charge had immediate consequences for Alison.
She was jailed while awaiting trial.
She remained incarcerated for 17 months.
Throughout that period, she maintained that she had not killed Kevin.
Her defense team argued that authorities had transformed an accidental death into a murder prosecution without sufficient evidence.
The stakes could not have been higher.
If convicted, Alison faced the possibility of spending much of the rest of her life in prison.
Her attorneys therefore had to do more than offer another interpretation of the evidence.
They had to convince jurors that the state had not proved murder beyond a reasonable doubt.
Alison’s Defense Team Said Police Had the Wrong Person
Defense attorneys Andy Baldwin and Max Wiley represented Alison.
After the trial, Wiley described the case as an unusual example of what the defense believed was genuine innocence.
He said criminal defense lawyers encounter many cases in which facts can be contested, but he believed Alison’s case involved authorities charging the wrong person.
Baldwin also argued that the prosecution should never have reached the stage it did.
The defense challenged the central assumptions behind the homicide theory.
That included the interpretation of Kevin’s injuries and the absence of a proven murder weapon.
They also emphasized the lack of direct evidence establishing that Alison attacked her husband.
The defense did not have to prove exactly how every injury occurred.
The burden remained on prosecutors to prove murder.
Medical Experts Became Central to the Trial
As expected, medical testimony became one of the most important parts of the trial.
The state relied on the proposition that Kevin’s injuries were incompatible with Alison’s account of a fall.
The defense challenged that conclusion.
Injury reconstruction in staircase cases can be difficult because falls do not produce one uniform pattern.
A person can strike multiple surfaces during a descent.
The shape of the staircase, the victim’s position and the points of impact can all affect the injuries.
The jury therefore had to evaluate competing interpretations of trauma without an eyewitness who could tell them what happened.
That uncertainty became important when jurors began deliberating.
The Case Included Body-Camera Footage and Alison’s 911 Call
The 48 Hours investigation includes material that allowed viewers to examine the early stages of the case.
The program features body-camera footage from the New Haven Police Department recorded during the initial response.
It also includes Alison’s 911 call.
Those records matter because they capture Alison’s behavior and statements before she knew Kevin’s death would become a murder investigation.
The episode also includes police interviews, medical experts, prosecutors, defense attorneys and Alison’s father.
Together, those accounts show how the same scene came to support two conflicting narratives.
At first, police saw an accident.
Months later, they saw murder.
At trial, jurors had to decide whether the second interpretation had been proven.
Prosecutors Took Alison Davis to Trial for Murder
After 17 months in custody, Alison went before an Allen County jury in 2025.
The state presented its theory that Kevin had not suffered an accidental fall.
Prosecutors argued that his injuries indicated an assault.
Alison remained the accused person at the center of that theory because she had been in the house and had acknowledged that she and Kevin argued after returning from the tavern.
The prosecution asked the jury to view that argument as part of the circumstances that led to violence.
The defense presented a different picture.
A married couple had argued, separated for the night and then suffered a catastrophe when Kevin fell.
The fact that police could not explain every injury through the staircase did not, the defense argued, establish that Alison had committed murder.
The Jury Deliberated for About Six Hours
The case went to the jury.
Despite the complexity of the medical testimony and the length of the investigation, jurors reached a decision within about six hours.
Their verdict was clear.
Not guilty.
Alison Davis was acquitted of murdering her husband.
The verdict ended the criminal case against her.
After spending 17 months incarcerated, she walked out of court a free woman.
Her defense attorneys later pointed to the outcome as an important reminder that being charged with murder does not mean the state has proved that a murder occurred or that the accused person committed it.
A Juror Said the Prosecution’s Case Had “A Lot of Holes”
After the trial, one of the jurors spoke with 48 Hours correspondent Peter Van Sant.
The juror described significant weaknesses in the prosecution’s case.
The state had failed to close several gaps.
There was no murder weapon.
There was no eyewitness.
The initial detective had believed Alison’s story.
The case depended on interpreting Kevin’s injuries as evidence of assault while rejecting an accidental fall.
Those issues left the jury without proof beyond a reasonable doubt.
The speed of the verdict reflected how the evidence was received.
After months of imprisonment and a full murder trial, Alison was cleared in a matter of hours once the case was placed in the hands of the jury.
The Acquittal Did Not Change Police Chief Krueger’s Belief
James Krueger had been promoted to police chief by the time 48 Hours revisited the case.
He remained unconvinced by the verdict.
Krueger continued to believe Alison was responsible for Kevin’s death.
His concern centered in part on the upstairs bedroom.
He wondered whether evidence could have been hidden there while Willow prevented him from entering during the initial investigation.
He suggested that a blunt-force object might have been inside.
But the distinction between suspicion and evidence remained important.
Nothing recovered after the fact established that such a weapon had been present.
The jury had been asked to decide the case based on evidence, not on what might have been inside an unsearched room.
They acquitted Alison.
Alison’s Father Says Kevin’s Death Was an Accident
Steve Krause has remained one of his daughter’s strongest supporters.
He rejects the murder theory.
For him, the absence of evidence showing Alison attacked Kevin confirms what the family has maintained from the beginning: Kevin died after an accident.
Krause has described the case against Alison as an injustice.
He also speaks about the relationship between Kevin and Alison before Kevin’s death.
His account is not of a marriage defined by violence.
He remembers a couple who loved each other, used affectionate names and shared their lives with Willow.
That makes the events after Kevin’s death difficult for the family to separate.
They lost Kevin, then spent more than a year watching Alison face prosecution for killing him.
Alison Davis Was Acquitted, Not Cleared by a New Suspect
The outcome of the trial needs to be understood with precision.
The jury did not identify another person who killed Kevin.
Nor did the trial produce evidence that another attacker had entered the home.
Instead, jurors concluded that prosecutors had not proved Alison guilty of murder beyond a reasonable doubt.
That is the legal significance of the verdict.
Alison cannot be treated as convicted or legally responsible for Kevin’s death.
She was tried and acquitted.
The homicide theory may remain the personal belief of some investigators, but the criminal case ended with a not-guilty verdict.
The prosecution did not prove its allegation.
The Case Raises Questions About How Suspicious Deaths Are Investigated
Kevin Davis’ death illustrates the difficulty of investigating fatal injuries inside a home.
The original scene appeared to support an accident.
Medical findings later persuaded investigators that it might have been homicide.
That change in interpretation led to an arrest, 17 months of incarceration and a murder trial.
Yet the evidence that convinced police did not convince the jury.
The case therefore raises questions about when forensic disagreement becomes sufficient grounds for prosecution.
Medical evidence can establish that an injury is unusual.
It does not always establish who caused it.
When there is no weapon, no eyewitness and no direct evidence of an assault, interpretation can become the case itself.
That was the challenge prosecutors faced with Alison Davis.
Willow Became an Unusual Part of the Debate
Few murder trials involve an unanswered question about a family dog.
Willow’s role was not that she witnessed the events in a way investigators could use.
Her importance came from what she prevented police from doing.
Krueger did not search the bedroom because Willow confronted him.
Years later, he wondered whether that decision cost investigators the evidence they needed.
The theory remains impossible to prove.
Willow may have been protecting nothing more than the room she knew as part of her home.
Alison had warned police about the dog before the detective entered the house.
That warning could be interpreted as an attempt to protect Willow from police.
Krueger came to wonder whether it served another purpose.
No physical evidence resolved the question.
Alison Davis Is Free After Her Acquittal
After the not-guilty verdict, Alison left custody.
CBS reported that she has been living with her mother and father while trying to rebuild her life.
Kevin is no longer there.
Willow is.
The dog who became part of the police theory remains with Alison.
The acquittal gave Alison her freedom, but it could not return the 17 months she spent incarcerated or undo the death that began the case.
She continues to maintain that Kevin fell and that she had no role in causing his fatal injuries.
Under the law, the murder prosecution against her is over.
Kevin Davis’ Death Remains the Central Mystery
The criminal case answered one question.
A jury determined that the state had not proved that Alison Davis murdered Kevin.
It did not produce a universally accepted explanation for every detail of Kevin’s injuries.
Police Chief Krueger still believes Kevin was attacked.
Alison and her family maintain that he fell.
That unresolved divide is what gives “A Death in the Stairwell” its power.
Two interpretations developed from the same house, the same injuries and the same night.
One led police to an accident.
The other led prosecutors to murder.
A jury rejected the murder case.
“A Death in the Stairwell” Examines How an Accident Became a Murder Trial
CBS’s 48 Hours returns to the case by reconstructing the investigation from the first 911 call through the verdict.
The episode includes body-camera footage from the night Kevin was found, Alison’s emergency call, interviews with investigators, testimony from medical experts and accounts from both the prosecution and defense.
It also examines one of the investigation’s most unusual unresolved questions: whether the bedroom guarded by Willow could have contained evidence police failed to find.
The program does not change the legal outcome.
Alison Davis was charged with murder, spent 17 months incarcerated, stood trial in Allen County and was acquitted after about six hours of jury deliberation.
For police, Kevin’s injuries continue to raise questions about whether he was assaulted.
For Alison and her family, the answer has remained the same since the morning she called 911.
Kevin fell.
CBS’s 48 Hours: “A Death in the Stairwell” airs Saturday, August 29, 2026, at 10/9c on CBS, with Peter Van Sant reporting on Kevin Davis’ death, the evidence that transformed the case from an accident investigation into a murder prosecution, the missing weapon police never found, the unusual role of Willow and the trial that ended with Alison Davis walking free.
