Can my child go to jail if they are under 18 years old in N.J.?

Yes, New Jersey has several Juvenile Detention Centers throughout the state. The main detention center, which is known as New Jersey Training School, is located in Monroe Township, which is in Middlesex County. Although the potential exposure a juvenile faces if convicted of a crime pales in comparison to that of what an adult would have to serve, the exposure can be absolutely devastating.
