Police have called off the search for a Bristol man presumed dead after he was thrown from his boat on the Delaware River near Neshaminy State Park on Friday.

John J. Poltonowicz, 49, fell overboard when his speedboat hit a wake from a tugboat about 1 p.m. Friday, said Trooper Jeff Flynn of the New Jersey State Police.

Troopers from Burlington Marine Station towed the boat back to Neshaminy State Park, where it had launched, and searched for Poltonowicz Friday and Saturday.

"At this point they're not going to be conducting any more searches," Flynn said Saturday evening. "The normal patrols out there in the waterways are going to continue to go out, keeping in mind to look out for this individual."

Poltonowicz appeared to be alone, according to witnesses who saw him go overboard. It appears Poltonowicz had been working as a prison consultant, according to a personal website authored by someone of the same name.
