I have a relative in custody somewhere. I need to find where he is. Is there a way to locate inmates?
Most state departments of corrections will have a locator link for inmates under their custody on their websites. Here is a link to all state department of corrections websites: State DOC Websites
If you think this person is in the Federal system, here are links to the US Bureau of Prisons inmate locator (BOP).
The Federal Marshal's Service basically contracts for detention services, and there is no inmate locator for the Federal Marshal's Service detainees.
