Original air date: November 04, 2004
Episode plot summary: Starting in 1987, three murders were committed on the Western Las Vegas University campus, one of which provided Catherine Willows to investigate a suspect - John Mathers, security guard of the university. Mathers was arrested and convicted. Two years ago he was executed. But the night of his execution another murder with the same M.O. was committed. Eventually, Mathers turned out to be a copycat, responsible only for one murder, and the serial killer got away. And today, the evidence found by Greg Sanders at a fresh crime scene leads Catherine to the conclusion that the Blue Paint Killer is back. The latest victim, Kaitlin Rackish, is identified by her roommate, Mandy Cooper (Summer Glau). Mandy hadn't seen her in a few days. Tearfully, she goes over where Kaitlin was on the Monday Kaitlin was taken, which includes a trip to the copy shop and art class with Professor Cody Lewis. Catherine immediately focuses in on Lewis, who dated the Blue Paint Killer's first victim.
