A bachelor party contest to see who could stay underwater the longest ended in the death of a New Jersey man, according to police.

Baldwin County Sheriff's Capt. Brad King says 23-year-old Robert Zachary "Zach" Bunsa, of Basking Ridge, drowned Saturday at Georgia's Lake Sinclair.

King says Bunsa was trying to see how long he could hold his breath but didn't come back up.

Georgia Department of Natural Resources Cpl. Lynn Stanford says around 15 men at the party didn't realize he was still in the water and went to the house to look for him. Stanford says it was more than seven minutes before someone realized he was still in the lake. One of them dove down and pulled him out.

Bunsa was pronounced dead at the scene.
