"Butterflied" is the twelfth episode of the fourth season of CSI: Crime Scene Investigation.
The double murder of a young nurse and her boyfriend makes Grissom question his workaholic lifestyle.
A nurse is found dead in her house by her friend, who is also a nurse. The victim died in her spacious bathroom, posed with her head facing the door. 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.
