• Kelly Nash, 25, went missing from his Buford, Georgia home on January 5, 2015.
• He left the house without his wallet, car keys, or identification, but a 9mm handgun went missing that night.
• In early February, a fisherman discovered Kelly Nash’s decomposed body in Lake Lanier.
• According to sheriff’s officials, the 25-year-old accounting student was shot and drowned.

It has been revealed that a Georgia man who went missing in early January and was discovered dead in a lake a month later died of a gunshot wound and drowned.

Kelly Nash, 25, was last seen alive in the early hours of January 5 after waking up coughing and sneezing and telling his girlfriend, Jessica Sexton, that he wasn’t feeling well.

The man was gone by the time Sexton woke up at 7.30 a.m. He left the house without his wallet, ID card, or truck keys.

According to WSB-TV, the only thing missing from Nash’s house was a 9mm handgun with a single clip.

A man fishing at Lake Lanier on February 8 discovered Kelly Nash’s badly decomposed body.

The gruesome discovery came after a month-long exhaustive search by the missing man’s family and friends, who were aided by cadaver dogs. A $50,000 reward was being offered for information leading to Nash’s location.

Nash was discovered in the water wearing the same pyjama pants and dark shirt he was wearing when he stopped by a convenience store hours before going missing to pick up some items.

Sexton, his three-year girlfriend, said she had seen the 25-year-old play video games before they went to bed. He awoke at 4 a.m. with cold or flu symptoms, and sometime before 7.30 a.m., he walked out of his home on Jimmy Dodd Road, never to return, according to 11Alive.
