prosecutor larry crouch offered the jury this theory, that dave snuck out of his house in the middle of the night without waking his sleeping children, maybe even used a ladder to get out of the window, and got someone to give him a ride to debbie's house and entered her bedroom. >> i think he tried the stun gun on her and she screamed very loudly and he struck her with something more than once. at that point, i assume he suffocated her. >> then, said the prosecutor, he must have dragged debbie's body to the garage, put her in her own van, disposed of her somewhere and drove to fresno. how did he get back home? that accomplice, said the prosecutor, must have picked him up and driven him the 40 miles back to his farm. but really, there was no body, no dna, no forensic evidence to show dave had even been at the murder scene. everybody in town seemed to have a theory, apparently the prosecutor did, too. but proof? so the state tried to build a bridge from dave's alleged financial crimes to a murder, painting him as an evil man who
