the new trial granted, we wanted to hit that head on. what that man did actually was throw something in the garbage can right beside the door. that guy was never identified? never identified. reporter: for heck, the heart of the case was that david dooley was the only one to leave the warehouse that morning. this was a bloody, violent murder. they would be covered in blood. there were no bloody clothes found on the scene. whoever did it left and when you looked at the video camera, he s the only one who left. reporter: one of the things that could have been covered in blood. dooley s steel toed work boots, required footwear at the warehouse. heck told the jury dooley might well have gotten rid of his boots to cover up the crime. where are his boots? they searched his house, his garage, his feet, his truck. and these were never found. reporter: so, did dooley leave work to check on his wife, or to get rid of bloody evidence? david dooley s statement was that he went home
pool of blood. the investigation that followed would peel the lid off an entire company and take a hard look at every employee who was there that morning. you know your suspect is one of those people in the building. that s right. probing t for clues in the victim s private life. the detective asked me if there was any trouble in their marriage. eliminating suspect after suspect until there was one. and just when it seemed to be over, it wasn t. if you had a sexual relationship, are you denying that? it s none of youre business. you re not controlling this anymore. you re not the commonwealth attorney here. c they say the wheels of justice turn slowly. in this case the wheels came completely off, leaving a family wondering who would do the right thing for a kind and loving woman who went to work one morning and never came home?
several weeks later, in which janet seems to admit saying her husband never came home. i ve been spendin the last few days reviewing all all of the interviews that we ve done with you. and i said can i just when when dave left for work that morning, when is the very first time that you saw him, after he left for work? and you said, when you guys let him go that afternoon. that s how i remembered it. so the second time, they went over her first statement with her and said, you told us this, this, and this. and she said, yep, that s how i remembered it. she said the exact same thing, and that is that david dooley did not come home. reporter: prosecutor heck acknowledges not knowing exactly why david dooley would have wanted to break into michelle s office and why he would have killed her. but to heck the fact that david dooley was double dipping on time cards, and that michelle handled payroll, and that the dooley s time cards from that week were never found,
