Authorities say a second person has been arrested in the abduction and killing of a Mississippi couple and their 7-year-old son.

The Mississippi Bureau of Investigation said early Thursday that 30-year-old Cedric D. Mason, of Jackson, was arrested late Wednesday on two counts of capital murder and two counts of kidnapping.

Authorities found the family's wrecked and burned vehicle Saturday in a remote area southwest of Jackson. Police say after they questioned 42-year-old Timothy Ladell Burns, also of Jackson, he led them the bodies at an abandoned home about a mile from the vehicle.

Burns has been charged with two counts of murder and arson. Authorities have not released a motive for the killings or said whether Burns and Mason knew the family.

All three victims had gunshot wounds.
