Charles Ballard was 25 when he was shot and killed in Chester, Pennsylvania, on the evening of June 28, 1990.

Authorities investigated the killing and arrested a suspect who was later tried on a murder charge. At trial the defendant was found not guilty; a news report described that person as a lifesaver. With that acquittal, no one was convicted in Ballard’s death.

If anyone has memories of that night in Chester or information that hasn’t been shared publicly, can you help fill in what happened?
