Zakkee Alhakim, 33, of Philadelphia, and Julie Jean, 34, of Elkins Park, are each charged with homicide, conspiracy and related offenses in Rachel King's death. King's 11-year-old son was in the backseat of the car at the time of the shooting. The alleged motive was King's relationship with her boyfriend, who had been involved in an affair with Jean last year, Montgomery County prosecutors said.
