My boyfriend has violated his Level 2 Probation for not reporting and
picking up new charges, we live in New Castle Delaware. He has 8
months left, Is there a certain percentage that he could possibly be
doing in jail?

Hi. I am not a google researcher, but have some info that might help.
There is a website that has very good info/support for people with
loved ones in the corrections system(s). www.prisontalk.com

The forums are usually quite "busy" and someone will ceratinly be able
to help you there. (free to join)
