Police said the owner of the house found the body inside the rental home where former KIRO radio personality Mike Webb lived before he disappeared in April.
Police said it is impossible to tell whether the body is that of Webb.
"The body is badly decomposed at this time," said Assistant Police Chief Nick Metz. "We can't determine the person's gender, age, race, and that all will not be able to be determined until we work with the King County Medical Examiner's Office to determine all of that."
Webb was last seen on April 13th and has been reported missing since. Police said they searched Webb's home after the initial report of his disappearance, though they can't specify exactly when they made their visit.
