The 1995 murder case of Bonnie Horinek was one where blood spatter evidence was considered more closely than the other elements of the case. Warren Horinek, Bonnie's husband and a former Fort Worth police officer, claimed Bonnie committed suicide. Prosecutors, the medical examiner and homicide detectives believed in Warren's innocence.

However, the moment Bonnie's parents received the call from Warren claiming Bonnie killed herself, they knew it was not suicide. Previously the police were dispatched to the Horinek home after Warren shot his weapon in the backyard during an argument with his wife. In addition, Warren admitted to shooting the gun towards Bonnie one night after another argument. He claimed he was aiming above Bonnie's head while she lay in bed with the intention to scare her. This was his explanation for the bullet defect in the wall. It just so happens, that was the same bed where Bonnie's lifeless body was also found.

Bonnie's parents hired Tom Bevel of Bevel, Gardner & Associates, who was able to prove to the jury the blood spatter evidence on Warren's shirt was not only proof he was in the room when the death occurred, but it was also evidence of a murder. Based on Tom's expert testimony, Warren Horinek was convicted and sentenced to 30 years in prison.
