It has been one week since three teenage girls vanished in Virginia, and officers with the Prince William County Police Department believe they could be in grave danger.

The FBI is involved because the search started crossing state lines.

Police said the three missing young girls disappeared from somewhere in Bristow, Virginia which is a small community about 30 miles outside of Washington, D.C.

However, a police spokesperson would not reveal precisely where teenagers were last seen.

Ashley Lemus, Breonia Thomas, and Chamareya Wright were reported missing last Sunday and listed as runaways.

Five days later, on Friday of last week, detectives had reason to believe something could be wrong and that girls could be in danger.

Prince William County Police sent out an alert on social media and got the FBI involved.

The girls are believed to be out of the state and driving a small, silver SUV.

An FBI spokesperson told WUSA9 there is no indication that the disappearance is gang-related, but it is unusual.

It is out of the ordinary for three young girls to vanish together and lose contact for a week, the FBI spokesperson said.

Ashley Lemus was last seen wearing a Nike sweatshirt and gray leggings.

She has a tattoo that reads “stay strong” on her chest and has other tattoos on her arms and wrists.

Breonia Thomas was last seen wearing a colorful romper and a purple bandana.

Chamareya Wright, who is the oldest in the bunch, had on a sweatshirt and leggings the last time she was spotted.

Police can’t offer any context around how the girls disappeared and why the department stressed that they firmly believe they could be in danger.
