Police said Monday that Sincere Camps killed the victim, 28-year-old Anshul Kuncha, during a robbery on June 5.
Investigators said Kuncha had just made a delivery at the Raymond Rosen homes on the 2300 block of Edgley Street when he was shot.
Inside the vacant apartment, officers found three pizza boxes and a bag, which appeared to be untouched, leading investigators to believe that the victim successfully delivered the items before being shot outside.

Police say Kuncha was found lying on the ground unresponsive, bleeding heavily with a gunshot wound to his head. He was rushed to the hospital, where he was pronounced dead.
At the scene, police recovered three spent shell casings, just inches away from where the victim was found.
