New Mexico PBS recently sat down with our senior reporter Joey Peters to break down the scandal that engulfed Albuquerque Public Schools over the past month.

In the segment, which aired over the weekend on New Mexico in Focus, journalist Sarah Gustavus interviewed Peters about how he found out that former APS Deputy Superintendent Jason Martinez’ previously undisclosed arrest charges of sexual assault of a child. Martinez also faces domestic violence charges.

This revelation eventually led to last week’s resignation of APS Superintendent Luis Valentino, in large part because Martinez never completed a required background check.

All school employees must complete background checks.
