A woman's body has been found in a stretch of parkland near where an 83-year-old grandmother was believed to have gone missing after arriving on a flight at Reagan National Airport in Washington D.C., police said.

The U.S. Park Police, which is leading the investigation, has not yet confirmed if the body is that of Victoria Kong, who was last seen leaving the airport Friday evening after arriving from Barbados.

Kong, who may have a form of dementia, according to family members, was captured twice on video immediately outside the airport before she disappeared.

She was last seen "walking north on the Mount Vernon trail toward Gravelly Point," according to the Metropolitan Washington Airports Authority Police Department.

The plan was for Kong to be met by airline agents with a wheelchair before departing the plane, but she instead left the plane on foot alone.

Video cameras captured her Friday evening standing near a line of taxis outside the airport, and then heading north, according to ABC affiliate WJLA.

"We have been up and down the trails … in and out of the airport," said one of King's granddaughters Kalisse Anderson.

"We are still prayerful … we are still holding the faith … we love her so much, and we just want her to be with us," she said.
