Niz-Mendez was located in O’Brien County after being arrested on state charges of operating while intoxicated and eluding law enforcement. Sentencing will be scheduled following completion of a presentence investigation report. Niz-Mendez remains in the custody of the U.S. Marshal.
He faces up to two years in prison for the illegal reentry conviction and up to 10 years in prison for failing to register as a sex offender, along with potential fines and supervised release.
The case was investigated by the Department of Homeland Security and prosecuted by the U.S. Attorney’s Office as part of Operation Take Back America.
