Pierre Clark was shot and killed in broad daylight on June 8, 2016, on the 1000 block of Montgomery Street in Alexandria, Virginia. Police arrived at about 12:35 p.m. and found the 28-year-old suffering multiple gunshot wounds to his upper body; he was taken to Inova Alexandria Hospital and pronounced dead a short time later. The shooting, in the neighborhood where Clark grew up, prompted temporary lockdowns at nearby schools and public facilities and drew community memorials and a candlelight vigil.

Investigators focused on a suspect identified as Saquan Hall. Before that investigation could proceed to court, Hall was shot on July 2, 2016, on the 1000 block of First Street in Old Town by Pierre Clark’s brother, DiJuan Marquie Clark, who pursued Hall and shot him in the head. Hall later died at a hospital. With the death of the identified suspect, the homicide investigation into Pierre Clark was closed in May 2017. DiJuan Clark later pleaded guilty to second-degree murder and a firearms charge and received a 31-year prison sentence; he said he believed Hall had killed his brother.

Did anyone in the neighborhood see either shooting or the events that followed and not yet share that information with authorities?
