A Clay County high school janitor faces up to 30 years in federal prison after he reportedly filmed female students changing inside a locker room back in August.

Jason Brian Goff, 42, employed as a janitor at Clay High School in Green Cove Springs, was arrested and charged with attempted production of child pornography.

On Aug. 22, two 14-year-old female students reported a camera in an unassigned locker in the girl's locker room. School officials inspected the locker and discovered a cellphone was taped inside with the camera lens pointing out of a "pre-fabricated hole" aimed at the changing area, according to the complaint.

Authorities reviewed the content of the phone and found images and videos of high school girls, ranging between the ages of 13 to 18 years old, changing inside the locker room, between Aug. 13 to Aug. 22, the complaint said.

In the last video, about a minute after a girl leaves the room, authorities say footage shows someone removing the phone from the locker. Before the video stops, the person who removed the video had a Clay County School identification badge, the complaint said. The badge reportedly matches Goff's Clay County School badge, according to the complaint.

The phone also contained a selfie of Goff and text messages from his own phone number, authorities say.

Goff was arrested and charged with attempted production of child pornography. If found guilty, Goff could face between 15 to 30 years in federal prison. His detention hearing is scheduled for Tuesday, Sept. 17.

Clay County School spokeswoman Nicole Young offered this statement:

Goff is currently employed through Clay County District Schools as a custodian at Clay High School. Goff is suspended pending the outcome of an investigation by the Department of Homeland Security. The District hired Goff in 2012 after an extensive background check required for all employees. At no time during Goff's employment were there any concerns relating to his tenure. Upon receiving notification of the investigation, the District took immediate action and will continue to partner with all agencies involved.
