A week after a body was pulled from a small Gwinnett County lake, investigators have not yet released his identity. And that’s agonizing for the family of missing pharmacy intern Alvin Ahmed.

“We’re still stuck with nothing,” Ahmed’s brother, Kalvin, told The Atlanta Journal-Constitution on Wednesday.

Alvin Ahmed, 25, was last seen July 16 when he walked out of the Loganville Publix following his shift at the pharmacy there. He had a bag of groceries for his mother, but he never made it home.

Ahmed’s car was found in the store’s parking lot, and it looked like someone had rummaged through it. His family said he didn’t have enemies, but had encountered some young men on his way in to work that wanted to know how much money he made. Ahmed mentioned the interaction to his co-workers.

His family pleaded for help finding the recent University of Georgia graduate, hoping someone saw something that might offer clues to his disappearance. Two days later, a woman called police to report seeing something in the water of Lake Carlton, about two miles away from the Publix. It was a man’s body.

An autopsy was conducted, but the body was badly decomposed and investigators said they needed dental records to make an identification. Those records proved inconclusive, Kalvin Ahmed said. The Gwinnett medical examiner’s office is continuing its work to determine whether the body is Alvin.

“I wish I could describe the pain of having a missing family member and feeling like there is nothing that you can do, but I can't, and I can't even imagine how my mother and the rest of my family are dealing with it,” Kalvin Ahmed posted on Facebook.

Alvin's former classmates at Loganville High School, where he graduated in 2011, created a Go Fund Me page to assist the Ahmed family.

“Looking from outside in, it breaks my heart to see this is happening around my little town where I grew up,” one woman posted on the fundraising page. “Prayers sent to Ahmed’s family and friends.”

Divers have searched Lake Carlton for additional clues but have not located additional evidence, according to Sgt. Jake Smith with Gwinnett police.
