BERKELEY COUNTY, SC (WCSC) - Investigators say the motive for the double-murder of two St. Stephen women was robbery.
According to authorities, 23-year-old Caleb Matlock and 22-year-old Arthur Chavis wanted to steal the victims' car.
Earlier on Friday, the Berkeley County Sheriff's Office filed additional charges against the men. According to court records, Matlock and Chavis are now charged with armed robbery and two counts of possession of a weapon during a violent crime.
Matlock is also charged with third-degree arson. Bond was set at $340,000 for Matlock and $280,000 for Chavis on the new charges.
Both men were charged with murder on September 1, days after authorities recovered the bodies of 18-year-old Dana Marie Woods and 22-year-old June Guerry in a section of the Francis Marion Forest near the Cordesville area.
Both victims were shot dead, authorities said. Search crews were led to the area after a fisherman stumbled upon Woods' burned-out Chevrolet Metro.
Court documents state Matlock told someone he and Chavis shot and killed them with a 9mm handgun.
According to Berkeley County Sheriff's Office reports, Woods and Guerry didn't return home from a trip to get fast food late in the night of August 26. Woods' mother contacted authorities after her phone calls to her daughter went unanswered in the early morning hours Monday.
Both women were laid to rest over the weekend.
Chavis and Matlock are being held in the Hill Finklea Detention Center. They are expected to appear in bond court on Friday evening to face the new charges.
