The body of a man was found at the Alviso Marina in San Jose on Saturday, and the Santa Clara county coroner is investigating whether it is a 49ers fan who has been missing since last Monday’s game at nearby Levi’s Stadium.

The body was reported to San Jose police Saturday at 2:52 p.m., and the agency promptly alerted the Santa Clara Police Department, which has been searching for Ian Powers, 32, of Spokane, Wash.

Santa Clara police Capt. Wahid Kazem said his agency was informed of the discovery and that it was a male. No other information, including whether the man was wearing 49ers gear — a red hat, red T-shirt and jeans — as Powers had been, was provided, he said.

“At this point, there’s nothing official to link” the two cases, Kazem said.

The Santa Clara County coroner’s office is working on identifying the body and cause of death. Coroner’s officials did not return calls Sunday.

Powers was last seen near the end of the 49ers’ football game at Levi’s Stadium Monday night after he told his girlfriend he was going to the restroom. Surveillance video from the stadium showed him walking on a footbridge with many other fans. His car was found where it had been parked nearby, with no signs of foul play.

Anyone with information about Powers’ disappearance is asked to contact the Santa Clara police at 408-615-5580.
