Joey Krenshaw is Harold Krenshaw's cousin who appears in Mr. Monk and the Daredevil. When Joey learned that his rich uncle Ronnie was nearing death, he decided to try and kill Harold. Luckily for him, he found the wreckage of Victor Grajna, a daredevil known as the Frisco Fly. After knocking out Harold and putting him into the Frisco Fly's suit, he threw him off a building, hoping to kill him, but he survived. Joey tried again, attempting to throw Harold off the roof of the hospital he was staying at, but Natalie Teeger and Adrian Monk arrived in time to stop him. Joey reappears in Mr. Monk's 100th Case as one of the criminals interviewed by James Novak.
