A 58-year-old boater drowned after his boat capsized Friday night at Captree State Park in Islip.
State police, state parks police, Suffolk County Marine Patrol and the Coast Guard say they responded to the scene of a reported boating incident around 8:37 p.m.
The investigation revealed that the boater attempted to launch his 16-foot vessel, which was seen striking the docks repeatedly before capsizing.
His body was recovered from underneath the vessel. Officials say he was taken to Good Samaritan Hospital and pronounced dead.
No other details have been released. State police say the investigation is ongoing.
