Michael Mason, 34, was shot and killed on June 13, 2015, while visiting a neighbor’s apartment at an east-side Indianapolis complex. Mason, who had a back condition and was prescribed pain medication, had been staying with his brother nearby and knew the neighbor, Thomas King, socially.

After the shooting, King asked another neighbor to hide the weapon and to give a false account to police. Investigation led to King’s arrest; prosecutors charged him with murder and with carrying a handgun without a license. King asserted self-defense at trial, but the state presented evidence that rejected that claim.

A jury convicted King and the court sentenced him to 62 years in prison plus three years in a community corrections program; the conviction and sentence were later affirmed on appeal.

If anyone knew Michael or was in that apartment complex on June 13, 2015, please share what was seen or heard that afternoon.
