Atlanta Crime Stoppers is asking for help in solving the shooting death of a man.

Home surveillance video shows a black man walking up to the door and firing shots into the room. Police said Cosby was struck by two different bullets.

"My grandson was a lovable person and for a person to come to my door and shoot at my door and murder him is hard for us to take,” said grandmother Doris Brown

Investigators said the shooter had a distinctive tattoo on his left hand.

“We want the public to really concentrate on that tattoo, as well as his face,” said Major Adam Lee II, Atlanta Police Department. “Normally we do not show this amount of information in video form of the crime scene, but based on us not receiving enough information from when we initially released the video, we decided to take it a step further.”
