Authorities Tuesday confirmed that a body divers recovered from the Petaluma marina was that of an elderly man missing for two days.

Sonoma County Coroner's staff confirmed the identity of Wilbur Dillman, 75, of Petaluma. Sgt. Greg Stashyn said that how Dillman died wasn't yet known. An autopsy took place Tuesday.

Dillman was a longtime resident of a boat moored at the marina, Petaluma Police officials said.

Dillman's neighbor called police Friday afternoon after thinking it odd that he wasn't on his boat, police said. Officers searched the area and local hospitals but found no sign of the man.

Divers from the Napa County Sheriff's Office recovered his body Sunday morning from the water.

Authorities were still waiting to identify two other bodies found in and around Petaluma's waterways since August in unrelated circumstances.

They hoped DNA evidence would identify a woman found Aug. 16 in an undeveloped area of the McNear Peninsula near downtown, Stashyn said. They were also still awaiting analysis of fingerprints to determine the identity of a man found in Willow Brook Creek near several homeless camps on the north end of town.
