John David ’Jack’ Shockley, 24, was shot and killed in the early morning hours of August 12, 2020, in a McDonald’s parking lot on North Emerson Avenue in Indianapolis. He had stopped after going through the drive-thru and parked to eat when a black Nissan Xterra with distinctive taillight damage pulled into the lot, passed his car, left, then returned and backed into a space beside him. The Xterra’s driver exited, a brief altercation occurred, and Shockley was shot. He was not discovered until hours later when a McDonald’s employee found his car and alerted authorities; he was pronounced dead at the scene from a gunshot wound.

Surveillance footage and witness statements were central to the investigation and identified Sammy Tinnin as the primary suspect. Tinnin was initially charged in August 2020; those charges were dismissed in February 2021 due to evidentiary problems but were later refiled in August 2021 after additional evidence emerged, including Tinnin’s fingerprints on the vehicle door matching the spot the shooter touched in the video. In January 2023 a jury convicted Sammy Tinnin of Shockley’s murder and he was sentenced in February 2023 to 60 years in the Indiana Department of Correction.

Does anyone have information about Jack Shockley’s routine that morning or about the black Nissan Xterra that could help clarify what led to the confrontation?
