Here, in L.A. crime has decreased drastically. So much so that the police can now work on cold cases (I love "Cold Case" on A&E)AND use DNA tests that weren't around twenty years ago. They've solved two cases, cases I remember reading about and the person arrested in each case was a HUGE surprise, shocking even. But it all goes to my theory that we all know someone who has killed, got away with it and keeps it as a deep dark secret that only they know about.
Take for instance John Floyd Thomas.
Well, well, if it didn't come back five months later that Thomas' DNA matched the DNA left and stored for thirty years in the bodies of at least six elderly white women in the 1970s and 1980s who were raped and strangled. They called this guy the "Southland Strangler" and could never catch him. All they knew was that he was black and that they kept the semen from the bodies of the victims.
His co-workers at the state office were in a state of shock. They had been working with a serial-killer who thought he had gotten away with it and turned over a new leaf. I do wonder how he was able to get such a good job with his record of 12 years in prison.
