On the afternoon of Sunday, April 28, 2024, a dispute in Manchester, Maryland, began an escalation that would prove fatal for 18-year-old Mauricio Guzman-Leon. The young Hispanic man had gone with his 23-year-old brother, Rudy Guzman-Leon, to a home in the 4900 block of Hanover Pike. They were there to retrieve mail or a "government card" that belonged to Rudy. An argument broke out during the visit, and the brothers left the property.
Later that same day, Mauricio and Rudy returned to the Hanover Pike address. This time, the encounter turned violent. A resident of the home, 41-year-old Jose A. Manchame, opened fire on the brothers. People in the area reported hearing at least five gunshots. As Mauricio and Rudy tried to flee in their vehicle, a bullet struck Mauricio in the head. In the ensuing chaos, their vehicle was involved in a car crash.
Rudy Guzman-Leon, who knew the shooter because his son was a friend, drove his critically wounded brother to the Carroll County Sheriff's Department in Westminster to get help. From there, Mauricio was airlifted to the R Adams Cowley Shock Trauma Center in Baltimore. Despite the efforts of medical staff, Mauricio Guzman-Leon succumbed to his gunshot wound on May 4.
The investigation by the Carroll County Sheriff's Office quickly led to the arrest of Jose A. Manchame. An examination of the brothers' vehicle revealed the violence of the encounter: two bullet holes were found near the driver's side mirror, another was at the top of the windshield, and a bullet was recovered from the front passenger seat. Manchame was indicted on charges of second-degree murder and the use of a firearm in the commission of a crime of violence. Following his indictment, he was convicted for his role in the fatal shooting and was sentenced in October 2024.
