"Well unfortunately every jurisdiction deals with some stalking cases, but we haven't quite seen a case like this," said Douglas County District Attorney Mark Jackson.
59-year-old Reno resident Rodney Skan was caught Saturday stalking a student after years of inappropriately filming female athletes. Officials say Skan hasn't only been stalking girls at Douglas County High School, but at high schools all over Northern Nevada for more than 10 years.
"And in this particular case, we truly believe the evidence would establish that he was taking these videos for one reason and that was for his own sexual gratification," said Jackson.
Jackson says they've collected hundreds of videotapes from Skan's home and he says there are multiple tapes of specific girls.
"He was focusing in and zooming in on the face and then on the buttocks area," said Jackson. "The girls wearing the volleyball spandex or the track athletes wearing the spandex, but he was focusing in on the front and then behind."
The Douglas County Sheriff's Office and the District Attorney's Office is working with all local high schools to try and identify victims and notify families. And if you attend any school activities, authorities want to remind everyone to be aware of your surroundings.
"People need to be vigilant and ask those questions and maybe get somebody involved as far as law enforcement to follow up and see what's going on," said Sgt. Pat Brooks with the Douglas County Sheriff's Office.
Skan pleaded guilty Monday to a misdemeanor charge of stalking. He has been banned from schools and sporting events across northern Nevada. His sentencing in Douglas County is set for June 12. Skan may still face prosecution in other jurisdictions.
