William Putnam is a recurring character in the first and second season of the Hulu Original Only Murders in the Building. Originally believed to be the son of Oliver and Roberta Putnam, it is eventually revealed that William is actually the son of Teddy Dimas. He lives in New Jersey with his mother, Roberta.
William's relationship with his father, Oliver, is problematic and tense, and the two rarely see eye-to-eye. Nonetheless, William turns to Oliver when he needs assistance, such as during the directing of his school play, The Wizard of Oz.
