Barry Mills Jr. was 14 when he was shot in the head and killed on February 21, 2021, in the 1900 block of Tolston Street in Chester Township, Pennsylvania. He was found at the scene, taken to Children’s Hospital of Philadelphia, and later died; the Philadelphia Medical Examiner’s Office ruled the death a homicide.

Authorities charged 20-year-old David Cobb with criminal homicide, third-degree murder, and related firearm offenses in connection with Barry’s death. Witnesses said Cobb was joking around with a rifle and accidentally shot Barry. Cobb reportedly turned himself in on March 10, 2021, was held without bail at the George W. Hill Correctional Facility, and a preliminary hearing was set for March 25, 2021. Detectives Patrick Mullen and Merritt Harman of the Chester Township Police Department were involved in the investigation, and multiple witnesses positively identified Cobb as the shooter.

The Delaware County District Attorney Jack Stollsteimer described the case as a tragedy that ruined two lives and left two families grief-stricken. If anyone knew Barry, was at the Tolston Street gathering that day, or has information about what happened, please share what is known.
