INDIANAPOLIS (AP) — An Indiana man whose criminal case led to federal charges against former Subway pitchman Jared Fogle has appeared in court for an initial hearing on child exploitation charges.

A federal magistrate asked 44-year-old Russell Taylor during Friday’s hearing if he understands the charges he faces and advised him of the maximum penalties. Taylor was then remanded back into federal custody.

Taylor is expected to plead guilty Dec. 10 to child exploitation and child pornography charges. He’s admitted using hidden cameras to produce child pornography involving 12 minors.

Prosecutors say their investigation of Taylor led to charges against Fogle, who they say received child pornography from Taylor, the former head of Fogle’s Jared Foundation.

Fogle has agreed to plead guilty to receiving child pornography and paying for sex with minors.
