On March 14, 1995, Warren Horinek called 911, claiming his wife Bonnie had shot herself. When paramedics arrived, they found Bonnie dead. She was lying on the couple’s bed with a gunshot wound to the chest. Warren was frantically administering CPR. On the bed next to Bonnie’s body was a .38 revolver and a shotgun. There was no sign of a break in. Police quickly narrowed the possible scenarios: Either Bonnie had committed suicide or Warren had murdered her. Warren claimed from the beginning that Bonnie had killed herself.
The people normally responsible for prosecuting a murder came to believe that Warren was telling the truth. The crime scene investigator, the homicide sergeant, the medical examiner and the assistant DA assigned to prosecute the case all became convinced that the evidence pointed to suicide.
“I always thought that it was suicide,” Mike Parrish, the prosecutor handling the case, told the Observer last year. “Still do.”
Bonnie’s parents chose to hire a private attorney, who, through a quirk in the law, obtained a grand jury indictment of Horinek. That led to a bizarre trial. Everyone trying to convict Warren was in private practice, and the agents of the state—crime scene investigator, homicide sergeant and assistant DA—all testified for the defense.
It seemed Warren was headed for acquittal until the testimony of the prosecution’s final witness—a blood spatter expert from Oklahoma named Tom Bevel. He testified that the small spots of blood found on Warren’s t-shirt the night of Bonnie’s death were certainly the result of blood spatter form a gunshot. He said the spatter proved Warren had fired a gun the night of the murder.
It was Bevel’s blood spatter testimony that led to Warren’s conviction.
The problem is Bevel may well have been wrong. Several nationally known blood spatter experts have examined the Horinek case and strongly believe the blood spots resulted from Warren administering CPR to Bonnie. They say the key forensic evidence that sent Warren to prison is flawed.
