A Braselton man swimming in Lake Lanier died after being pulled Monday night from the water, and a friend who attempted to save him was treated for water inhalation.

Quentin Aaron Muse, 20, was pronounced dead at Northside-Forsyth Hospital after Forsyth County marine units administered CPR, according to a news release from the Forsyth County Sheriff’s Office.

He was  underwater for about 40 minutes before he was found about 9 p.m. Monday off the Shady Grove Campground beach by the Forsyth County Fire Department’s dive team.

He was taken to Northside Hospital-Forsyth in an attempt to resuscitate him, according to Robin Regan, a Sheriff’s Office spokesman. He had not been pronounced dead because of the “fast recovery time.”

Muse was not wearing a lifejacket, according to the Sheriff’s Office, and no foul play is suspected.

The friend apparently attempted to save Muse after hearing him yell that he was having difficulty swimming back to shore. The friend was not transported to the hospital.

The men were part of a group of four who had reached a buoy just past the swimming line, not more than 100 feet from the beach, Regan said.

The sheriff’s marine patrol unit had been patrolling the area, and the fire department responded within 15 minutes of the call about 8 p.m., though it was not immediately clear who notified 911.
