Kevin Neal, Convicted of Murder by Forensic Entomology
Neal was also unable to account for approximately six hours between telephone calls he made to his aunt, looking for a place to stay. During those telephone calls, the aunt, Carolyn Gragg, noted that she did not hear the sounds of children, the usual background noise during calls from Kevin.
Just as damning was the fact that Neal had told investigators that a Bonneville automobile parked near the house didn't work and hadn't been driven in more than a month because the brakes were shot. The farmhands were willing to testify that when they arrived at the scene, the Bonneville was not present.
A search warrant was issued for the car, and it was taken to a local garage, where a mechanic was asked to examine it. When the tow truck arrived to take the vehicle away, the truck operator slowly backed the vehicle out of its storage spot and surprised everyone when he instinctively applied the brake and the car stopped. When it was put on a lift at the garage, the mechanic found a set of vise grips sealing a brake line as some sort of temporary fix.
