A judge denied bail today for a South Side man accused of killing another man after arguing with him and telling him, "I'll be back with my gun," according to police.

Today in court Judge Israel Desierto denied bail for Victor Willis, 22, of the 5700 block of South Michigan Avenue, who has been charged with murder, according to authorities.

John Wallace, 25, was shot dead around 11:30 p.m. on Sept. 1 in the 6400 block of South Morgan Street in the Englewood neighborhood, police said. He and Willis had argued while on the porch and Willis left saying: “I’ll be back with my gun,’’ police said.

In court, Asst. States’ attorney Bridget O’Brien said the slaying happened as one of two witnesses was hanging out on a front porch where they both live at the Morgan Street address. A still-uncharged suspect came to the home with his girlfriend and he began taunting the witness about a previous fight that the two witnesses had been involved in over a girl they both knew, according to O'Brien.

When a second witness told everyone to leave the porch, the uncharged suspect got mad and left with his girlfriend in a van. But a few minutes later, he came back with Willis in the same van, being driven by his girlfriend, O'Brien said.

One of the witnesses was now sitting on a porch across the street and saw Willis, who he knows as “Vic” wearing a red hoodie and holding a handgun with an extended clip as Willis and the uncharged suspect exited the van and approached the porch, according to O'Brien.

The victim, who was not involved in the prior altercations and “just happened” to be there at the time, answered the door. When he refused to tell Willis where one of the witnesses was, Willis began firing several shots into the building hitting the victim five times, before entering the home, raising the gun, and still firing, according to O'Brien.

The co-defendants fled and Willis was arrested on Sept. 11 and positively identified as the shooter.

In 2009, Willis was convicted of a possession of a stolen motor vehicle for which he was given two years probation. He also has two failure to appear violations, prosecutors said.
