EAST POINT, Ga. - A metro Atlanta family is praying for the public's help as investigators try to track down the killer of their loved one on the anniversary of his death.
Robert Green Jr., 29, was shot and killed on April 4, 2017 outside of his home on Spanish Trail, according to East Point Police.
Detective Ebony Johnson told FOX 5's Marissa Mitchell the details are slim on the case and they're still hoping to get leads. Right now, they only know that Green answered a knock on his door and was shot multiple times. His nephew and four-year-old daughter were the only people inside the apartment at the time, according to Johnson.
"You have someone who is out here and who has murdered someone. They are a threat to the public," Detective Johnson stressed. "It's imperative that we find out who this person is."
Mitchell sat down with Green's sister, Tonya Green, Friday. It was the family's first time speaking publicly about the case.
"It has been a year. But every time I think about it, I am still shocked," Green said. "It's the grief of separation and the second thing that is agonizing is the fact that we don't know the why and we don't know the who."
Green leaves behind two daughters, one of whom was born after his death, according to his sister.
Anyone with information about the case is asked to call Crime Stoppers at 404 577-TIPS (8477). Tipsters can remain anonymous and there is a cash reward for any information that leads to an arrest.
