Duplicate listings across facilities are more common than you might expect, particularly when an inmate has been recently transferred and both the old and new facility records have not yet been fully updated in the database. It creates confusion but it is usually a timing issue rather than a mystery.
The most reliable tool for locating current custody status is VINELink at vinelink.com. VINE stands for Victim Information and Notification Everyday, and while it was built primarily as a victim notification system, it is publicly accessible and pulls current custody data directly from facility records across most states including New Mexico. Search your person by name or ID number and it will show you where they are currently registered in the system.
For New Mexico specifically, the New Mexico Corrections Department also maintains an offender search tool on their official website that can help confirm current facility placement for state inmates. If he is in a county facility like Otero County, the county detention center itself is often the most accurate source since their records update in real time as transfers occur.
If VINELink and the state database are still showing conflicting information, calling Otero County Detention Center directly and asking for the records or intake department will get you a definitive answer faster than any online search. Have his full legal name and date of birth ready when you call.
InmateAid's inmate locator is also worth trying as an additional resource if the other searches are not resolving the conflict.
