And...for those who are upset at the intrusion/digging into the private lives of NC's friends, remember if you will, in 2002 when 7 yr old Danielle Van Dam was taken from her home (by a neighbor) and found dead 3 weeks later, the parents 'lifestyle' was put on trial as much as the defendant's. The parents were part of a semi-occasional swinging lifestyle and they enjoyed smoking pot, drinking and a little spouse swapping at times. They were castigated by the San Diego community as well as the entire country for their behaviors. Of course those behaviors didn't have anything to do with the actual crime itself, but the inference was made many times that their behaviors somehow enticed their pedophile neighbor Westerfield into sneaking into their home in the middle of the night, abducting their daughter, driving her in his motorhome for 3 days, and eventually killing her and leaving her body about 10 mi. away for predators to feast on.
But in the end, none of the salaciousness mattered to the jury. David Allen Westerfield was connected to the victim and the crime through his timeline, DNA, fibers, kiddie *advertiser censored*, failed polygraph test and other things. It wasn't a 'slam-dunk' case by any means, but he was found guilty AND is now sitting on death row in San Quentin.
People CAN (and will) see through smoke screens and pay attention to the actual evidence. The key of course is that there must be evidence linking the killer to his/her victim in some way.
