(KPHO/Gray News) - A school janitor in northwestern Arizona is accused of giving vape pens and alcohol to girls in exchange for naked photos of them.

The Mohave County Sheriff's Office said Thursday that Pierce Anthony Eller, 41, is facing more than a dozen charges.

Investigators said Eller works as a janitor at a Kingman-area school through a private contractor, and the vape-for-explicit-photos trades started in February with an underage family friend.
