Police now believe 20-year-old Derek Still borrowed a phone and managed to get a bicycle and ride it to I-30.
Still was serving a two year sentence for a non-violent offense but could now face felony charges.
Detectives say he escaped when prisoners were being brought out to the exercise yard.
If you see Still, call 911 right away.
