BENSALEM, Pa. -

Searchers trying to find a suburban Philadelphia man who fell from his boat into the Delaware River say they now consider it a recovery mission.

The Bucks County Courier Times reported Sunday that 49-year-old John Poltonowicz was seen jumping wakes left by a passing tugboat on Friday before he fell into the water.

The paper says the Bristol resident may have lost his balance, after which his boat circled in the river until it ran out of gas.

Witnesses report he wasn't wearing a life vest and was alone in the boat.
