A prominent builder for celebrities’ homes was identified by authorities Sunday as being one of four people on board a small plane that crashed off the coast of Long Island, killing two and leaving two missing.

East Hampton Town Police identified the people as 70-year-old builder Bernard Krupinski, 70-year-old Bonnie Krupinski, 22-year-old William Maerov and 47-year-old Jon Dollard.

The Federal Aviation Administration said the Piper PA31 aircraft that the four people were in went down about 3 p.m. Saturday. The crash scene was about a mile and a half (2.4 kilometers) south of East Hampton. Saturday’s weather included severe thunderstorms in the area.

Two bodies were recovered, and the Coast Guard on Sunday resumed the search for the other two people before suspending it. It was not immediately clear which of the four passengers had been recovered.

“We are stricken by this loss,” said Capt. Kevin B. Reed of the Coast Guard. “Our deepest sympathies go out to the families and loved ones of the two recovered individuals.”

The National Transportation Safety Board will investigate the cause of the crash.

Eastern Long Island is known for its celebrity presence, with many wealthy and prominent individuals spending time there, particularly in the summer months.

Small planes and helicopters are popular, as a way to avoid the bumper-to-bumper traffic on the Long Island Expressway.

Bernard Krupinski grew up in East Hampton before starting his business, Ben Krupinski Builders, there. As a builder, his clients included Martha Stewart and Billy Joel.

The National Transportation Safety Board will investigate the cause of the crash.
