On New Year’s Day 2014 in North Charleston, South Carolina, 52-year-old Janet Royal was shot and killed. Royal’s death shocked her family, who lost a mother and cherished relative.

In the months that followed, investigators say Royal’s stepson, Jimmy Harris Jr., carried out retaliatory attacks. He is reported to have fatally shot Deborah Randall Martin and to have wounded Ford’s mother in a separate shooting, escalating the cycle of violence and widening the families’ losses.

For years the incidents remained under investigation. If anyone knew Janet Royal, Montreal Ford, Deborah Martin, or Jimmy Harris Jr., or has information about the shootings in North Charleston on and after January 1, 2014, contact the authorities handling the case.
