MANALAPAN, Fla. (AP) - A Canadian man died after going for a late night swim off a South Florida beach.

Manalapan police say 46-year-old Dinu Constantinescu was swimming with a small group around 2 a.m. Tuesday when the others lost track of him. They had initially assumed he went back to the Ritz-Carlton Palm Beach, where he was a guest. The group notified employees when they returned to the hotel and couldn't find him.

Two police officers went to the beach and found Constantinescu floating in shallow water. Palm Beach County Fire-Rescue responded, and the man was taken to a nearby hospital, where he was pronounced dead.

Authorities say the man was visiting from British Columbia for a business conference.
