Lancaster County District Judge Darla Ideus said Dylan Will s attitude, actions and repeated unlawful acts led her to conclude he is a danger to the public.
The teen was last seen being picked up in a silver sedan while wearing a black hoodie, loose blue jeans and a black backpack with the word 'NOVA' written on it.
Dylan Will, 22, fled the scene in the immediate aftermath of the crash but returned 30 minutes later and told authorities he hadn t been driving, police alleged.
