ORLEANS — A 22-year-old New York man trying out for a lifeguard position died while taking part in swimming trials at Pilgrim Lake on Saturday morning, officials said.

Jack Jakubek, of Newburgh, slipped beneath the surface at 8:49 a.m. and was found unconscious by an Orleans Fire Department diver in 10 to 15 feet of water about a half-hour later, officials from the Orleans fire department and Cape and Islands District Attorney's Office said.

Lifeguards and fire officials who were at the Pilgrim Lake beach for the lifeguard tryouts immediately started searching for the man after he didn't surface, Deering said. An Orleans Fire Department diver, who is part of the Barnstable County Dive Team, found Jakubek 150 to 200 yards from shore at 9:23 a.m., Deering said.

Rescue crews tried to resuscitate the victim and brought him to shore by boat, but he was declared dead after being brought by ambulance to Cape Cod Hospital in Hyannis, Deering said.

The incident is under investigation by Orleans police and Massachusetts State Police. Jakubek was listed as a lifeguard in the Orleans 2014 annual report.

The lifeguard fitness tests conducted by the town of Orleans are an annual event for people hoping for lifeguard positions at Nauset Beach in the summer, fire Chief Anthony Pike said in a brief press conference at Pilgrim Lake. Pike said he could not go into the details of the incident, as it was still being investigated.

Pike said the tryouts started at 8 a.m. and typically last about an hour. Although it varies from year to year, tryouts usually consist of 15 to 18 guards, he said. The Natural Resources Department oversees lifeguards in the town, Pike said, and fire staff monitor the tryouts. Lifeguards were deployed today to the town's beaches, Pike added. Natural Resources officials were not immediately available for comment.
