A social evening at The Park at Hoover apartments in Hoover, Alabama, ended in a homicide shortly after 6 p.m. on a Sunday in November 2019. Robert Michael Lyons, 55, and 24-year-old Austyn Reese McMillian had been spending time together earlier that night when a disagreement escalated into a heated argument and a gunshot was fired.

Officers who responded to the 200 building found Lyons with at least one gunshot wound; Hoover Fire-medics attempted aid but Lyons was pronounced dead at the scene. McMillian did not flee and remained at the location, surrendering to responding officers; he was taken into custody and charged with Lyons’s murder.

What details about the argument or the events leading up to the shooting have not been released? Anyone with information about that evening is asked to come forward.
