SALEM — A Massachusetts man is accused of rigging cameras underneath a trailer and then hiding there while video-recording a woman and her toddler son as they used the bathroom.

The woman, who resides at 15 Friendship Drive, called police Wednesday night when she saw movement in the air duct in her bathroom floor, looked into it and saw a man peering up at her from underneath the floor vent. “Hello,” the man said, and she immediately called 911.

She told police she knew the man, who they identified as Christian Hobbs, 44, of Orleans, Mass., because she bought the trailer from him and he had done some work on it two weeks ago.

Hobbs was walking south on Route 28 when police located and confronted him. “I did it, it was me under the trailer,” he blurted out to the officers, according to a press release. He was arrested without incident.

According to police, two weeks ago when Hobbs was working on the trailer, he installed two baby monitors — one in the bedroom and one in the dryer duct in the residence. He later went under the trailer and cuts holes in the floor and in the floor vent in the bathroom.

Police said Hobbs stayed under the trailer for nearly two days with food, beverages and tissues, observing and taping the woman when she was in the bathroom. He allegedly had 16 one-minute videos of the woman, some including her nude toddler son.

Hobbs is charged with prowling, criminal mischief, violation of privacy, unlawful wiretapping, manufacture of child pornography, criminal trespassing and burglary.

What's next: Hobbs refused bail and was transported to Rockingham County jail, pending arraignment Thursday in 10th Circuit Court, Salem District Division.
