Police in South Carolina say they were able to find a man wanted in a double homicide because he was wearing a GPS device after an earlier burglary conviction.

Myrtle Beach Police Lt. Joey Crosby told local media outlets that 29-year-old Calvin Derrell Ford of Myrtle Beach was arrested Sunday and faces two counts of murder and weapons charges.

The charges stem from a Saturday night shooting following an argument outside a city fire station. A police report says firefighters heard gunshots and then pounding on the station door.

They found two critically injured men identified as 26-year-old Dameion Hakeem Alston and 27-year-old Marquis Jamal Burgess, both of Myrtle Beach. Both died later at a hospital.

Ford is in jail. It was not immediately known if he had an attorney.
