DOUGLASVILLE, Ga. — A heartbroken family has replayed the tragic incident of their loved one in their heads for the last 15 years.
Maryanne Humphrey, 62, of Douglasville, was working the night shift on September 21, 2009, at the former Circle-K near Arbor Place Mall when authorities said she was shot to death after the suspect cleared out the cash register.
On Tuesday, the Georgia Bureau of Investigation, Douglas County Sheriff's Office and Douglas County District Attorney renewed calls for information that could lead to finding the person responsible for killing her. Authorities released a new age-progression photo of who they believed the suspect was.
Humphrey's granddaughter, Kailyn Kaiser, held back tears as she expressed her desperation to find her grandmother's killer and get justice.
"I've come to an understanding within myself that I may never know the answers or the questions or even if that person is brought to justice. Although that may be my understanding with the new procedures and evidence that has been released, we are in higher hopes that we may release the grip of the closure we've been desperately wanting since this tragic accident we replay in our minds than we wanted to," Kaiser said.
The Douglas County Sheriff's Office also gave more information on the case that could lead to a new turn.
"Somebody knows something. They deserve closure; this is the only family on the anniversary of the death that calls every year," Cpt. Jon Mauney.
Cpt. Jon Mauney said the office had a pair of sneakers remade by the manufacturer to try to find the suspect. He added that the shoes were special at the time, and not a lot of people had them.
Authorities added that although the 2009 surveillance footage is grainy, it has enabled them to develop the latest clues in the investigation.
A former Douglas County Sheriff's Office deputy previously told 11Alive that Humphrey fought to expose her killer on surveillence, who was hiding his face behind a blanket at the time of the incident, leading to the current clues that exist today.
The suspect was described as being between middle teens and early 20s at the time and was around 5 feet tall. Authorities believed the suspect was a young man.
GBI agents said the neighborhood was experiencing epic flooding the night of the tragic incident, which could be affecting the investigation. Still, authorities want to make sure "no stone is left unturn."
"This was a night of epic flooding. Anything that could possibly trigger your memory at that moment let law enforcement know. Even the smallest, most minor details can solve this case. Fifteen years is a long time for this family to wait," said Douglas County District Attorney Dalia Racine.
Authorities are offering a $25,000 reward for anyone with information on the case that could lead to closure for the family.

"We are hoping that with this new evidence that has been released, we will finally get the closure we have been wanting," said Kaiyln Kaiser.
