Police located the teen in Ellenboro, West Virginia just a couple of hours after the alert was issued.
Police say 15-year-old Alexandria Miller left a note at her home on Jackson St. stating she was taken against her will.
Investigators say the teen also left a message on her sister's cell phone asking for help.
The West Virginia State Patrol spotted the car Miller was in.
While the teen does have a history of running away, police felt it necessary to issue the Amber Alert.
“There is still quite a bit of confusion,” said Dan Rainey, Miller’s uncle. “At this point we are just relived that she is alive and well and apparently is being transported back. “We're waiting for details just like everyone else. We are very grateful for the Amber Alert and the prompt response by our law enforcement.”
Three people were found in the car with Alexandria and they are all now in custody.
Last week police say the teen ran off with two of the suspects.
