Police said Mahley had installed mirrors on the interior doors of the a bathroom stalls and inspected all schools and facilities that Mahley, an employee of Multi-Temp for eight years, may have had access to.

Camden County Acting Prosecutor Jill Mayer on Thursday said investigators found videos of six girls and one adult. The videos were found on multiple devices seized from Mahley’s West Deptford home and his work vehicle, according to Mayer.

Mahley was charged with seven counts of second-degree endangering the welfare of a child (manufacturing of child pornography), eight counts of third-degree invasion of privacy, and seven counts of third-degree endangering the welfare of a child (possession of child pornography).
