OAKLAND -- A man who died from a stab wound and several injuries after being found on an East Oakland street may have committed suicide or could be the city's latest homicide victim, police said Wednesday.

Police are exploring both possibilities after initially investigating the early morning death as a homicide, Sgt. Arturo Bautista said. Police were called to the 2300 block of International Boulevard at 5:14 a.m. after a passer-by discovered the man's body with several injuries, including a stab wound.

"We're looking into (suicide) as a possibility, because people we've interviewed were saying he's been down and out and that he'd talked about it," Bautista said. "We're following up on that information."

However, it was too early to rule out a homicide, Bautista said.

"All possibilities are being considered," he said.

Police also received reports that the man may have jumped or fallen off something, but they had not confirmed those initial reports, Bautista said. The man was taken to a hospital where he was pronounced dead.
