I was wondering if I could find out over the internet if someone has violated parole or do I have to call the actual parole office?

Try looking at the county's website to see if they list people who are wanted --

Most information like that is not on the web. You could call up and speak to the actual parole officer to really find out. But if they were violated, they most likely would be in jail.

I doubt that you will find out, you may find out if they are in jail, but a PO is not going to give out private info on a person to someone just calling up on the phone.

So give us info on,
1. what is your relationship with this person
2. what makes you believe they have violated their probation
