ATLANTA — Family members of a grandmother missing for more than two years are trying to generate leads in a case that's gone cold.
Pat Moss, 77, vanished from her Riverdale home. Her nephew just wants to know what happened.
"How do people disappear? Just vanish?" Moss' nephew Charles Brown said.
That question that keeps bringing him back to Atlanta at least twice a year to find out what happened to his missing aunt.
"I feel horrible I feel really sad for my mother it's her sister and my other aunt they're … our family is really, really small and there's not many of us here, so we have to have hope it's all we have left in a situation like this," Brown said.
Moss was 77
years old when she disappeared from her home Sept. 4, 2011. She suffers from Alzheimer's and dementia.
Channel 2 Action News was there with Brown two years ago when he went door-to-door, passing out fliers, hoping to generate leads. But since then, nothing. The case has gone cold.
Clayton County police say shortly after Moss disappeared a woman called them saying she dropped Moss off at Hartsfield-Jackson International Airport. But there's no indication that she bought a plane ticket and there's been no contact with her ever since.
"It is considered a cold case but our cold cases are always active cases we continue to work them," said Clayton County Police Capt. Angelo Daniel.
Daniel said though it's been an unusually long amount of time, his detectives are still investigating.
"We haven't had any leads and we encourage anyone with information to come forward it is critical that we speak with them," Daniel said.
"Someone must know something," Brown said.
Brown just hopes by him being here, and asking questions, it will trigger a memory from someone.
"We're going to keep hope alive. I'm going to keep trucking back to Atlanta as often as I can so that no one forgets my aunt pat," Brown said.
