forenics

I love watching all shows on forensics; Forensics files, CSI Miami, Suburban Secrets. One episode i remember was on suburban secrets. Three college girls shared a house together they were all in their twenties. Two of the girls were going to Australia on some study together for a couple of months. One night two of girls were murdered the ones that shared a bedroom they were stabbed and killed. The third girl survived because she had her own bedroom. They had no idea who did they had no evidence they later found out that the girls boyfriend was very jealous. He apparently did not want her to leave, and he was did not like her friend either because she was going with her. They took a close look at the case and re observed it, the night of the murder their was a cigarette on the floor in the house, it was a very rare cigarette you couldn't get it in most places. However after cross examination, they realized he smoked that brand of cigarettes, they did DNA on the cigarette butt and it was a match to him. He plead guilty to murdering the two girls. Some people are really crazy i don't know how someone can have the mind set to stab 2 innocent girls multiple times to death all because she was going away. Sometimes you can never tell people just snap . I have seen episodes where people were married for 30 years and murder their spouse over an affair , money, jealousy or simply no reason just cold blooded killers. Today's science and technology can really almost test and find out anything just by putting the pieces together of a case. Their is no such thing as a perfect murder their is always something their that tells you a dark story, threw science.
