A 49-year-old Gwinnett County man drowned Tuesday evening at Lake Lanier.

The man, identified as Gideon Massey Burt, swam to retrieve a beach ball, called for help and was not seen again, Hall County fire Chief David Kimbrell said.

Burt, of Lawrenceville, was in the water near the campground at Lake Lanier Islands when he was reported missing around 6:15 p.m., Kimbrell said.

Hall County divers found the man's body around 7:20 p.m. in 32 feet of water.

The sheriff's office is investigating the death, Kimbrell said.
