Sheriff Paul Penzone suspended the posse program Jan. 25 after an audit showed only four of the posse's 235 members cleared to carry guns were actually qualified to do so.

A member of the Maricopa County Sheriff's Office North Valley Posse faces a misdemeanor disorderly conduct charge after a domestic violence incident.

The sheriff's office said that Phoenix police officers arrested Keith Mendivil Friday and booked on the misdemeanor charge.

Mendivil had been a member of the posse since 2016, but MCSO said it was removing Mendivil from the program after his arrest.

The volunteer program itself has also been under a microscope recently after an audit revealed that sex and drug offenders, as well as domestic violence convicts, were among its ranks. MCSO said earlier this month that those offenders had been removed from the program.

The audit also showed only four of its 235 members who were cleared to carry guns actually had the qualifications required to do so.

MCSO blamed the oversight on poor record-keeping under former sheriff Joe Arpaio, who fostered the posse program.
