Daniel Katums was a mass murderer in Montana and the archenemy of Lindsay Monroe, as well as the primary reason why she became a CSI. He appeared in seasons three and nine of CSI:NY.


Back when Lindsay was living in Montana, she was enjoying some time with her friends in a local diner and went to the bathroom. While she was in there, Daniel came into the diner, armed with a shotgun, and robbed it. He then shot and killed all of the witnesses before leaving, not knowing Lindsay was in the bathroom and had witnessed the massacre. Lindsay called the police, but he managed to get away with the crime for ten years.

Season Three[]

Sleight Out of Hand[]

After spending ten years on the run, Daniel was apprehended. Lindsay was due to stand as a witness in his court case, testifying against him. It was then that she remembered the memories she had repressed about Daniel and how he murdered all of her friends. Eventually, after a very lengthy court case, Danny came to listen to the verdict and to support Lindsay. It was revealed that the jury had decided that Daniel was guilty of the mass killing. He was sentenced to death, leaving him enraged and seeking revenge on Lindsay.

Season Nine[]

Late Admissions[]

Years after Katums's conviction, Lindsay returned to Montana to clear the air with him before his execution. During their meeting, he insists that she misidentified him and he is innocent; Lindsay reveals that she was aware that he filed a series of appeals following his trial, most of them based on that claim. However, she remains firm on her identification and demands to know what the cost of all those lives Katums took was worth it, referring to the proceeds of the robbery. At the end of the episode, Daniel Katums is executed by lethal injection, his last words being that he was sorry for what he did.
