About CSI: Crime Scene Investigation Season 4, Episode 12 :

A nurse is found dead in her house by her friend, who's also a nurse. The victim died in her spacious bathroom, posed with her head facing the door. Grissom is left unnerved because the victim bears a resemblance to his fellow CSI, Sara Sidle. According to the friend, she was to have dinner with her new boyfriend, Dr. Michael Clark, who works at the same hospital. Processing the crime scene reveals very little evidence because the killer has thoroughly cleaned the place and used bleached to denature any DNA. Dr. Clark, initially a prime suspect, is later found, albeit in pieces, in garbage bins behind the house. The precision of various cuts suggests that a medical personnel is the killer. Meanwhile, this case prompts Grissom to contemplate his workaholic life and whether it is worth the life he may be missing out on.
