The woman, whose body was found under a bridge in Dillon County Thursday afternoon, was killed at a home in Marion County Wednesday, according to Sheriff Mark Richardson.
The body of Tina Scott Locklear, 40, was found by a man walking Allen's Bridge looking for cans. The bridge spans the Little Pee Dee River at the Dillon-Marion county line.
Investigators have served a search warrant at the home where they believe the murder took place. They've collected evidence that has been sent to the State Law Enforcement Division for testing.
The sheriff's office has a person of interest in custody at the Marion County Jail on a unrelated charge.
