Alex Wilfredo Mendoza Ramirez, 30, was found dead on the concrete walkway outside Building I at the Gates of Summerville apartments on Boonehill Road in Summerville, South Carolina, on the evening of June 4, 2017. Summerville police were dispatched about 8:39 p.m. after reports of shots fired; officers located Alex with at least one gunshot wound to the head and neck area and pronounced him dead at the scene.

Investigators treated the death as a homicide. A resident of the complex, 21-year-old Wayne Jamal Pinckney, called 911 and remained at his apartment until officers arrived; police located and arrested him and charged him with murder and possession of a firearm during the commission of a violent crime. According to statements taken that night, Alex and his roommate had gone to Pinckney’s apartment to confront someone over suspected fake marijuana, the confrontation spilled outside, and several people inside — including two infants — said they did not see the shooting. Witnesses reported Pinckney told a woman to call 911 and said he was protecting himself.

Police appealed for tips through Crime Stoppers in the days after the killing. Does anyone who knew Alex or was at the Gates of Summerville that night have information that could help clarify what happened?
