John Maletsky, 27, of Chester, Pennsylvania, was fatally shot on January 21, 1984. He was stopped at a traffic light with his four-year-old daughter in the car when two assailants pulled him from the vehicle, shot him again, and fled with the child. Maletsky later died of his wounds.

The investigation led to the arrest of Michael Campbell, whose fingerprints were found on Maletsky’s car. Michael Campbell was convicted of robbery, second-degree murder, kidnapping, and criminal conspiracy in connection with the killing. His brother, Dean Campbell, was implicated and made statements that were later the subject of legal challenges; appeals and motions argued those statements might have had exculpatory value for Michael, but the convictions were ultimately upheld and Michael Campbell was sentenced.
