A bachelor party at a Georgia lake went horribly awry when one guest drowned after he and his friends had a contest over who could stay underwater the longest.

Robert Bunsa, 23, was invited to the bachelor party which was taking place in Lake Sinclair.

Bunsa traveled to Baldwin County in Georgia from his home in Basking Ridge, New Jersey, according to The Macon Telegraph.

On Saturday evening, Bunsa and some of the other estimated 15 guests were at a party.

Baldwin County sheriff’s Captain Brad King said that a number of the guests, including Bunsa, competed with each other which of them could hold their breath underwater the longest.

Bunsa failed to come to the water’s surface as the others had done, according to authorities.

The other guests all climbed out of the water and went into the house thinking that Bunsa had gotten out of the lake first.

But when they couldn’t find him inside the home, they sensed he was in trouble.

The sheriff’s office and the Georgia Department of Natural Resources were summoned to Annette Way near Rocky Creek at approximately 5:40pm on Saturday.

‘He was missing for some time - over seven minutes, at least, before they realized, and one of the friends did dive down and pull him out,’ DNR Corporal Lynn Stanford said.

She said that Bunsa was not far from the dock in water whose depth ranges from five to 10 feet.

But visibility in the lake is only about 1 foot, according to Stanford.

A law enforcement officer who lived nearby heard the distress call on the radio and rushed to the scene.

He performed CPR on Bunsa for between 10 and 15 minutes before paramedics arrived.

The authorities hoped Bunsa would survive long enough to be airlifted to a local hospital for treatment, but he was pronounced dead at the scene.

The Baldwin County deputy coroner listed the official time of death at 7:20pm.
