INDIANAPOLIS – Indianapolis Metropolitan police arrested a man Wednesday in connection with a weekend shooting at a gas station and food mart that killed two people.

Martice McGee, 20, was booked on two counts of murder. He’s accused of killing 26-year-old Jaquareous Rashawn Tyreik Mitchell and 29-year-old Jimmy Jermaine Thomas Jr.

The shooting happened before 5:30 p.m. Saturday inside Emerson Food Mart on North Emerson Avenue. Mitchell died at the scene, police said, while Thomas was taken to IU Health Methodist Hospital in critical condition. He later died from his injuries.

Investigators spoke with multiple witnesses and said no store employees were involved in the incident. They used surveillance video and fingerprints to identify McGee as the suspect.

Court documents state the shooting stemmed from an argument. Witnesses and McGee told police that Thomas threatened to fight McGee. Surveillance video showed that during the incident inside the store, Thomas gave Mitchell two handguns, and Mitchell walked out of the store with the two handguns and a rifle before returning with no guns in his hands, per court documents.

In an interview with police, McGee claimed he told Thomas, “If you touch me or approach me, I will shoot you,” documents state.

Thomas replied, “You’re bluffing if you had a gun, you would have shot me when I first came in,” recalled McGee.

McGee told police that Thomas continued toward him so he shot him and Mitchell. Surveillance video showed McGee shoot Thomas, then turn toward Mitchell and fire at him, court documents say. Mitchell returned fire but was shot several times.
