My husband has gotten into all these forensics shows of late,
New Detectives, etc. They are fascinating to watch, some of the cases you simply say "no way" that they will solve the murder, and then they go step by step to show you, really good stuff. Lots of these shows have guys convicted simply on circumstantial, they just lay out the case piece by piece, let the jury decide if they brought enough to get their suspect.
Billy Martin said yesterday that the police have a great deal of evidence, but he is not at liberty to disclose. I have watched several episodes where guys have been busted on less than we know already here -- let's hope that whoever it was, however this young lady met her demise, the information gets known.
It's a truism in forensics that every murderer leaves a little bit of himself at the crime scene and takes a little bit of the crime scene with him. Physical evidence is very impressive to most juries (exception would be the Simpson jury).
In a lot of cases, it just takes a strand of hair or a drop of blood, or a partial fingerprint. It's hard for a miscreant not to leave something of himself behind in a criminal case. After reading how Gary scoured his apartment before the police searched it, I'm beginning to wonder if he had anything to do with this. I can't imagine him or his minions leaving behind Chandra's possessions -- leggings, Walkman, whatever.
