Visit to a real crime lab

Yesterday we visited the crime lab in Peoria which was pretty cool we had several forensic techniques demestrated to us as well as seeing thier state the art car camera system Marty has been there for 6 years and worked on many cases one of the ones he told us about which i thought was most interesting was that of a serial killer in Peoria a few years ago who was rapeing and killing African Amercian prostatutes the police started bring in sex offenders and interviewing them and asking for bucal swabs which is swabing the inside with a qtip obtain cells for DNA anylisis the man the eventualy caught refused to cooperate and rather than throw his cigarette butts away he would stick them in his pocket so the police went and got a search warrent for his house and found bones in his fire ring so they brought him in again for questioning this time he made the mastake of droping one of his cigarette butts on the ground and Marty was happy to pick it up and send it to morton Illinois for DNA anylisis the test came back saying that his was the culprit and after they arrested him he conffessed to 8 rape/homicides DNA helped get another bad guy off the streets
