JACKSONVILLE, Fla. – It took a Duval County jury only five minutes to convict a man of second-degree murder in the in the shooting death of a man after a confrontation at a Northside gas station last year.

Isreal Williams was accused of shooting and killing 46-year-old Thomas Schadowsky as he was driving away from the confrontation at a Gate gas station on Dunn Avenue in February 2013.

Investigators said Williams admitted to getting into an argument with Schadowsky (pictured, right), whose body was found in his truck about 100 yards down the road.

In addition to murder, Williams, 42, was convicted of shooting into an occupied vehicle and possession of a firearm by a convicted felon.

Williams faces life in prison. He will be formally sentenced the week of Dec. 8.

During the trial, Williams claimed another driver in a dark sedan is responsible for the killing, and that he was merely a witness to a road rage incident between the two.

Evidence released earlier this year by the State Attorney's Office includes the emotional 911 call from Joe Theiss, the man who found Schadowsky's body slumped over the wheel of his pickup truck.

Theiss testified during the trial.

Williams was questioned by police a few days after the killing, and according to detectives, he admitted to getting into a confrontation, then backing his orange Chevy Avalanche with Florida A&M University tags into a parking spot and waited for Schadowsky to leave the gas station. He said he followed behind him, but as Schadowsky pulled out, Williams said Schadowsky cut off a dark sedan.

"I don't know what happened. I didn't shoot nobody last night," Williams told investigators.

He said he drove off and didn't see what happened after that. Witnesses told police Williams and Schadowsky's cars were the only ones there.

Prosecutors said he drove to the Department of Motor Vehicles in Callahan and told them someone stole his license plates. They were replaced.

Williams later admitted to police he threw his tags into a Nassau County dumpster, among other things, because he was "done supporting his daughter" who went to FAMU.

The prosecution showed evidence of gun powder residue found inside Williams' car near the passenger door, but no gun was ever found.
