SAN LEANDRO -- Authorities are seeking information about the person who dumped a dead 300-pound black bear outside a Foothill Boulevard market.

The adult male bear -- which apparently had been shot -- was left outside Terrace Market, at 16250 Foothill Blvd., early Sunday evening by someone in a white Dodge pickup truck that quickly sped away, said Sgt J.D. Nelson with the Alameda County Sheriff's Office.

Nelson said his office has very little to go on, other than the bear had been shot in its shoulder and dumped.

"I know for a fact it didn't walk up 164th Avenue to get there," said Nelson, adding his department and the state Department of Fish and Game were investigating the situation.

"There are probably a thousand different possibilities as to how and why it was dumped there," Nelson said.

Kyle Orr, a spokesman with the Department of Fish and Game, said there are approximately 40,000 black bears in the state; however, there are no known black bears living in the East Bay. Orr said it currently is bear-hunting season in the state -- which is expected to last until sometime in December.

Anyone with information may contact the sheriff's office at 510-667-3636 or Lt. Sheree Christensen with the state Department of Fish and Game at 925-556-0363.
