Tony Jr. Mason, shot Nov. 4, 2017 in Baltimore, has a major update: Dion Thompson was convicted in late July 2026 of first-degree murder, conspiracy and related charges and was also found guilty of attempted second-degree murder for the woman who was with Mason. Prosecutors say Thompson, who was about 18 at the time of the shooting, was tied to the case after a 2023 tip and will be/was sentenced on Aug. 5, 2026 to two life sentences plus 33 years. He was already serving federal time on unrelated drug and weapons charges when the murder charges were filed, and charging documents say he admitted he shot at the parked car because he was paranoid and later learned the victim was an off-duty officer. Investigators say the killing was a case of mistaken identity, and this conviction closes a long cold case that prob haunted Mason's family and colleagues while detectives worked thru tips and court records.
