FAIRFAX COUNTY, VA – A teen mom, who along with her son, were missing for nearly a month, returned home on Friday night, according to the Fairfax County Police Department.

“Lizzy Rivera Colindres returned home last night (February 11) shortly before midnight. She and the baby boy, Aidan, were in good health. We will continue to work with the family and provide assistance as needed,” the department said in a press release.

The pair had been missing since Jan. 15. Authorities believed Colindres

At first, detectives thought the girl left voluntarily with Aidan’s father, Jose Ivan Castillo Rivas, 18, however other developments suggested the teen mother and her baby might have been in danger and left with Rivas out of fear.

No word on the whereabouts of Castillo or if any charges will be filed against him.
