Last Thursday we watched one of the series of Law and Order. The film was about the cyber investigation on Dr. Tracy Conley murder case. Apparently Dr. Conley, a therapist, had 9 stab wounds. She was killed Monday night when she went on a movie with her friend, a basketball coach in Stanley High School (statement from her parents) but a friend of Dr. Conley said she spent the night with her sister named Monique which is 15 years old, this was never mentioned by Dr. Conley's parents. The investigators went to interrogate Monique, and she said she was just supposed to grab her sister's purse with Arnold. But this was not a strong argument. Tracey was writing a book with her co-doctors. Gary, the other co-worker of Dr. Conley, is getting her laptop because he was afraid that somebody else might took away their work. There are computer technology used to solve the crime:
