text:  The FBI has joined the search for a missing Pikesville girl with Baltimore County and Maryland State Police. The search for 12-year-old Tasia Alana Warren continues as she's been missing from nearly a week. She was last seen around 8.30 p.m. last Thursday, June 20th, in her Pikesville neighborhood. Tasia's friends have told family that she may have been communicating with a man in his 20s and may have tried to meet him. The Black and Missing Foundation has also posted information on its website, and you can find photos of Tasia on our website, WBAL.com.
