Ashlie Mae O’Brien told her guardians she was going to a friend’s house when she left home from the 8000 block of Oak Leaf Drive around 4 p.m. Friday, but she never arrived, police said.

The friend’s home is in walking distance of O’Brien’s home, said Lucy Caldwell, a spokeswoman for the Fairfax County police.

Detectives have followed up on numerous leads since O’Brien went missing and are now asking for the public’s help in locating the girl, police said. Caldwell said Ashlie is considered to be in danger because of her age.

“There are a set of serious, complex and confidential custodial issues involved in this case,” Caldwell said.

Ashlie is described as 5’4” tall, 130 pounds and has blond hair and blue eyes. She has braces and was last seen wearing a red and white jacket and yellow athletic shorts, police said.
