robert beatty: about the size of a eraser head, really. and the interesting part about that was that it was a drop that had fallen straight down. keith morrison: indicating to the troopers that she'd been hurt somehow before she got anywhere near the edge of the cliff. with it being five or six feet away from the cliff's edge, it was real apparent to me that we no longer have some accidental death. this was a homicide. keith morrison: but, because there was no sign of a struggle at the crime scene, no weapon, nothing more left behind, it was obvious this would be hard to solve. so, though eventually they told karen they agreed with her bonnie had been murdered, they wanted her to keep that information secret. fat chance. by then, karen was telling anyone who would listen what she thought. and she was not about to stop. so you spoiled it for them? yeah, i did. i got in trouble constantly for me getting involved in the investigation and also-- opening your big mouth to the media. yeah. keith morrison: she was troubled by something else, too.
