How can you find out if your boyfriend is on parole?

Every state DOC has a website or an office to call for inmate or offender information. The site for Michigan for instance is called OTIS. (below is a link to the Prison Legal News Offender Locator Link for all 50 states.)

By accessing the Inmate Locator, or Offender Information site, the status of an inmate who has been released on parole will indicate "Parole" or "Conditional Release."

You may need the offender's DOC number to access any information, and you will be required to call for information in some states such as California.
