The U.S. Coast Guard ended its search for a 58-year-old diver from Massachusetts who went missing Thursday morning off the coast of Palm Beach.
Around 6 p.m., the Coast Guard announced Robert K. Macintyre’s body was found by Palm Beach County Sheriff’s Office divers.
One person commented on the Twitter announcement that Macintyre was “such a wonderful person and dedicated physician. A tragic day for his family, friends and colleagues.”
He was last seen diving in a black wetsuit and a silver oxygen tank near Lake Worth Inlet, which is between Palm Beach and Palm Beach Shores, according to the Coast Guard.
He was with a group of people on a dive boat, the Coast Guard said.
CBS12 says the boat, Republic IV, had scheduled a 34 to 45 minute dive for the group. At some point, Macintyre went into the water and never came up again.
