Stach - Thanks for your interest. Let me try to answer your questions the best I can..
~they think it was one more than one killer because of the location of Cheryl vs Andy and the brutality of the crime. They also took them from their car into the woods.
~ I know they tested the ropes for all info back when the crime was committed and again recently. They used some sort of new testing and in a different lab
~ the goup she was hanging out with just gave me the creeps. the way they looked at me, treated me, etc. In addition, they were losers..... 20 and 21 year olds living at home, not going to school, not working, etc. Also, somewhat into drugs. One of their alibis was a drug dealer!! The gorup included an ex boyfriend but he had broken up with her. His good friend wanted to date her and she wouldn't because she said they had too great of a friendship. He didn't come to the funeral...so much for a good friend, huh?
LE has looked into all of this over and over again and don't feel like it is the group that I belive had something to do with it. They had to give blood samples, alibis, etc.
Thank you for your kind words, interest and support
