Police in Florida say a daughter suspected her mother’s live-in partner was having an affair, so she looked at files under his profile in their household computer.

Instead of another woman, the daughter found pictures and video of herself — naked and undressing in the privacy of her bedroom and bathroom.

Investigators eventually found more than 2,500 images taken with a secret camera. Sunrise police say 48-year-old Matthew Bordeaux, who has lived with the mother and daughter for seven years, was jailed on charges of video voyeurism.

The SunSentinel reports that Bordeaux was jailed on $10,000 bail after a court hearing Monday. It’s not clear if he has hired a lawyer.
