Around 9 p.m. Saturday night police were sent to 827 N. Wabash on the report of a shooting. On arrival, George Vasquez Jr., 23, was found lying on the floor inside with a gunshot wound to his head. He was pronounced dead on the scene.
Police say Vasquez was visiting with two men who lived at the home when he answered a knock on the door and was immediately shot.
Officers took two men who were arguing outside the home when police arrived into custody. Officials say one of them, Hakeem Jackson, 28, was later arrested and jailed for the murder.
Formal charges are expected to be filed by the District Attorney's office later Monday.
