most unusual cases we ve ever come across. police would end up investigating not just who but why. with answers as stunning as they were disturbing. as dawn broke that cold november morning, detective began with his perpetrator, sabrina. i first noticed that she was very small girl, very frail girl. sabrina started describing the moments leading up to the murder. she had had a migraine, she said, while everyone else slept, she walked into the master bath to get some ibuprofen and that she said is where her memory went blank. you didn t think anybody could stab someone that many times and not remember any part of it. no. i tried all different ways to get her to come out and tell me what really happened. and she was not giving it up. and then sabrina asked for an attorney, bringing the investigation to an abrupt and
finding out that the foster daughter lisa welcomed into her home ended up committing lisa s murder only added to the collective pain and suffering. betrayal is the perfect word for what happened. somebody hurting her that she had taken in, i just can t even imagine what she must have been going through. as detective ron worked the case, he learned there had been growing tension within the knoefel home right before the murder. and the source of that tension was sabrina. she got along great with kevin and she did not get along well at all with lisa. detective discovered lisa had become frustrated with sabrina s behavior toward kevin. she was fascinated with kevin. she seemed a little vivacious in my eyes, flirty. uh-huh. like flaunting herself.
