North Carolina authorities are desperately searching for a 15-year-old girl who may be "endangered" and is believed to have last been seen Monday with a man at a Walmart store.

The Guilford County Sheriff's Office said a female believed to be Amelia Hill was seen with an "unknown" man at a Walmart in Randleman, located about 20 miles south of Greensboro, between 9:45 and 10:30 a.m.

The two were seen on surveillance video walking together, and they left the store in a 4-door white Ford F-250 pick-up truck, according to the sheriff's office.
