Floyd Oscar, Jr. was shot to death in front of an apartment complex on Bob White Drive in July.
Shortly after Oscar was shot, police said a blue SUV, possibly a Dodge Durango, drove to the front of the complex and stopped near his body.
HPD officials said a woman got out of the vehicle and approached Oscar. Rather than call 911 for the victim, police said the woman went through Oscar's pockets instead.
The woman was seen wearing a blue T-shirt, jeans, red sneakers and had braided hair.
The SUV she was in was driven by a black man wearing a white T-shirt, black pants and had afro-style hair and a goatee.
Surveillance footage captured the suspects and the SUV before the fled in an unknown direction.
