A dispute that began at another location in Deerfield Beach escalated into a deadly shooting on the evening of July 19, 2026. Twenty-five-year-old Ryan Christopher McGowan was found with multiple gunshot wounds outside a residence in the 5100 block of East Lakes Drive after deputies were called to the scene about 7:12 p.m. Paramedics transported McGowan to a local hospital, where he was pronounced dead shortly after arrival.

Broward Sheriff’s Office investigators say the confrontation involved 27-year-old Mauro Lopez. Lopez remained at the scene, was detained by deputies and later arrested by the BSO Homicide Unit. He was charged with one count of second-degree murder with a firearm and one count of aggravated assault with a firearm; the case is pending further legal proceedings.
