On July 22, 2017, 23-year-old Teshon Malloy of Chester, Pennsylvania, was shot and killed. He was found lying in the street at the intersection of Thomas and Terrill streets and was declared dead at the scene. The Delaware County Medical Examiner reported Malloy had been shot twice in the head, four times in the torso, once in each arm, and once in the leg.

Investigators arrested 19-year-old Miguel Angel Moreno of Chester, who was known by the alias Yay-Yay. Witnesses said Malloy had been trying to break up a fight when Moreno shot him. A witness identified Moreno as the gunman, and he was arrested within 24 hours after voluntarily coming to Chester Police Headquarters with his mother and aunt. Moreno later pleaded guilty to third-degree murder and to firearms not be carried without a license and was sentenced to 11 1/2 to 33 years in state prison.

The case drew attention to ongoing gun violence in Chester and the number of homicides the city had experienced that year. If anyone knew Teshon Malloy or has information about the shooting, please come forward.
