CSI: NY: Necrophilia Americana

Mac becomes particularly protective of the only witness in his murder investigation, a young boy found in shock at the exhibit, who after seeing the grizzly crime, confuses the events at the museum with a comic book he was reading at the time. The team works to discover if the motive was money, given the curator's wealth, or if the witness has something to do with it when the CSIs find he has ties to the victim.
