Missing Great-Grandmother, Child Found Alive in Virginia

They had last been seen on Christmas Eve.

— -- A missing woman and her great-granddaughter have been found alive in Virginia, according to state police.

According to Virginia State Police public information officer Corinne Geller, the two were found in their vehicle on private property in Dinwiddie County. The property owner discovered them and called authorities, she said.

Briley was flown to VCU Medical Center in Richmond for treatment, Geller said, and La'Myra, who was alert and appeared unharmed, was transported from the scene for medical evaluation.

State police remained at the scene and are in contact with the lead investigative agency in the case, the Township of Hamilton Police Department in New Jersey.

No further information was immediately available.

Earlier on Wednesday, Briley's niece Marcella Rorie told ABC News that she was "beyond exhausted" searching for the two "but at this point, that really doesn't matter."

She added, "I need them found."

Briley and La'Myra intended to drive from New Jersey to North Carolina — a journey primarily on I-95, a stretch of road that is familiar to many East Coast residents who drive south for the holidays. Surveillance video from the Virginia Exxon station shows Briley walking to a register counter.

She asked for directions before her disappearance, according to Joanne Strange, a clerk at the gas station who spoke to ABC station WTVD in Raleigh, North Carolina. According to Strange, Briley struggled with the GPS on her phone.

The pair's family members told WTVD that Briley does not have any known medical conditions.
