Eddie Murdoch is a character featured in Season 5. He was a construction worker and enforcer for Foreman Peter Breen who was hired to kill a temp named Stefanie Preston. After strangling her, he set her house on fire, but as he walked away, forgot his boss's keys. He then broke into a firehouse to steal a fireman's coat, but was stopped by Rusty who he then killed with a shovel. Adrian Monk then charged him only for Rusty to throw a chemical compound into Monk's eyes, blinding him. He then went back to the scene of the crime to recover the Ferrari keys. When visiting Breen's construction site, Adrian had a second encounter with Murdoch, only this time he recovered a nametag from Murdoch. Breen saw Murdoch as a liability and threw him from a top floor to his death on his jobsite.
