More skeletal remains were found on New Year's Day near Ronald McNair and Tidewater Road in Horry County.
That's just a short distance from the bones found over the weekend.
Those remains were of a male, but testing is underway to determine the identity of the found Wednesday.
According to Horry County Coroner Robert Edge, the bones found Wednesday could have been relocated by animals and doesn't necessarily mean they are of a different person.
The new bones will be sent to Charleston to identify if they're human and the sex.
