GWINNETT COUNTY, Ga. — Authorities are investigating after finding a body in a metro Atlanta lake.

According to the Gwinnett County Police Department, the body was found in Lake Carlton in Loganville at around 8:15 PM Wednesday when someone called 911 after noticing something floating in the water.

Officials have identified the gender of the body as male and are treating the death as suspicious.

"Fire Department personnel responded with officers and used a boat to approach the object. They were able to confirm it was a deceased male," a release reads.

No I.D. or vehicle were found in order to properly identify the body so police are saying they are starting from square one.

"Loganville P.D., you have heard, is investigating a missing person. They've shared all of their information on that with us and so we are certainly taking all that into account as we look into this deceased person," said Sgt. Jake Smith.

"The caller was aware of the missing person case, so that was actually in her mind as she was observing whatever this was in the water and decided to call us and, yeah it was completely based off her phone call that we were able to come out and discover this at all. So, it does speak to the importance of when you see something suspicious, call the police," Sgt. Smith said.

The lake is about 30 miles east of Atlanta and 2.6 miles away from the Publix where a 25-year-old pharmacy tech was last seen. Police said they are aware of that missing person's case.

According to representatives for the family, Alvin Rowson Ahmed went missing July 16 after leaving his job at Town Center Publix in Loganville. They're concerned for his safety because his car was found in the parking lot with the groceries still inside, doors unlocked, his glovebox "rummaged through" and his white medical coat in the car.
