Detectives will canvass the shoreline of Babylon Town looking for video and other clues that may explain what happened to a Lindenhurst boater found dead in the Great South Bay on Monday.

The efforts come as the major case unit awaits results of an autopsy on Andrew Weis, 48, who was reported missing Saturday after he boarded a 13-foot dinghy, possibly on his way to the Anchorage Yacht Club in Lindenhurst to join friends, authorities said.

His dinghy had some damage when it washed up on Venetian Shores Park next to the club about 7:30 a.m. Sunday, and his body was discovered Monday about a half-mile south of Copiague Harbor after a massive search by local authorities and the U.S. Coast Guard.

Police said Weis may have been in an accident and said an accident reconstruction may be called for later.

For now, detectives want to see what homes and businesses are close to the waters, at least between Copiague and Lindenhurst.

“Maybe there’s a restaurant that has video, maybe there’s a fueling station or maybe there’s a home,” said Det. Sgt. James Brierton of the major case unit.

Police will also talk to boaters and go to areas with boating traffic to hear if anyone has noticed anything unusual, he said.

He urged the public to call with tips.

“We need to know because it might be one little piece of the puzzle that might help us,” Brierton said.

Detectives said anyone with information could call 631-852-6555 or Crime Stoppers at 800-220-8477.
