GRANBY, Colo. (CBS4) – Sheriff’s investigators are trying to figure out who was victimized by a rental owner who allegedly installed hidden cameras inside a carbon monoxide detector and a bathroom fan to capture women in private moments.

CBS4 confirms that several cameras and a hard drive have been collected from the house at 295 Mountain View Avenue (CR541) near Granby.

Investigators with the Grand County Sheriff’s Office say charges are pending against the owner of the home.

“We need to reach these women to identify them for this case,” Dan Mayer with the Grand County Sheriff’s Office said.

The recordings are suspected to go back three years or more, he said.

Investigators say the landlord found his victims on craigslist through postings looking for women who worked at Winter Park Resort. They say a woman who had just moved into the rental house discovered a camera and called police.

They are not ruling out the potential of minor victims.

The suspect has not yet been formally charged. Investigators are meeting with the district attorney in the morning to figure out charges.

Anyone who suspects being involved in this case are asked to call Pam Peschiera at 970-725-3853

CBS4 has a crew in Granby working to learn more details on this disturbing story.
