On the night of May 19, 2014, Patrick Lamar Martin, 24, was killed during a violent home invasion on Indianapolis’ Northside. Martin had been at a friend’s house where the occupants sometimes conducted marijuana sales when two intruders forced their way inside a home that also held eight children under age ten.

Witnesses said one intruder, identified at trial as 31-year-old Mark Tyson, was armed with a shotgun; the other, Keri Brewer, carried a box cutter. Tyson allegedly demanded money and property, pointed the shotgun at Aleem Thomas and later confronted Martin, accusing him of having cash. Tyson and Brewer fled the scene.

Police arrested and charged Mark Tyson with murder and robbery; during the trial four witnesses, including two of the children present, identified Tyson as the shooter. Anyone with information about Patrick Martin, the shooting, or observations from that Northside neighborhood on May 19, 2014, is asked to come forward.
