worked on how can you let this man walk the streets knowing he murdered our mother? her mother was brutally murdered. someone sat on her chest and stabbed her repeatedly with a knife. this is not somebody walked in and shot her. you want to talk about brutal and heinous murders? imagine your sister telling you she figured out who had done this most horrible thing to your mother and andrew said let's just call the police. catherine said oh, no, if we call the police -- >> they'll call me an accomplice and we'll both go to jail. catherine was robert's alibi and robert was my sister's alibi. if he goes, i go, her words. she says, you have to get rid of him. you have to do it for mom. >> cathy's mother was stabbed 37 times in the face and neck. that's not a crime for $100 in
