Alphonso Leon Griffin, 29, of Cantonment, Florida, was found with a gunshot wound in the yard of a residence in the 200 block of Sheppard Street on the evening of July 23, 2016. Emergency crews took him to Sacred Heart Hospital, where he died shortly after arrival.

Investigators identified 19-year-old Marquis Derrell Bryant as the primary suspect after a verbal altercation between the two escalated and Bryant allegedly shot Griffin. Bryant fled the scene and was arrested in August 2016. He was charged with first-degree premeditated murder, resisting an officer without violence, and grand theft of a motor vehicle. A jury convicted Bryant of second-degree murder on December 15, 2017, and he received a life sentence; a separate bribery charge led to an additional five-year term.

Does anyone have information about Griffin’s last known activities or the circumstances that led to the confrontation?
