BUCKS COUNTY, Pa. (CBS) — A former Bucks County nurse has plead guilty to secretly photographing and videotaping patients while they undressed.

Authorities say James Close was a nurse at Penn Medicine when he committed the crimes. He was charged in February with four counts of recording a 17-year-old. He was also charged with 43 additional charges involving seven other women.

Prosecutor Megan Stricker said, “We found 18 videos, four of those were of a minor that found the phone.”

On Friday, he plead guilty to the 48 counts he was facing, including four counts of sexual abuse of children, four counts of endangering the welfare of a child, 18 counts of invasion of privacy and various other charges.

According to court documents, the 17-year-old was undressed in a treatment booth when she noticed a silver iPhone on the ground. She told authorities it was recording. Documents reveal police found 18 videos on the phone.

Close’s attorney Ellis Klein said, “He’s been nothing but remorseful from day one, he’s never been in trouble a day in his life and he has a problem and he’s going to deal with it.”

In total, Close could face a maximum sentence of upwards of 100 years when he is sentenced at a later date, Prosecutors note it’s too early to say what penalty they will seek, as Close still has to have a sexually violent predator assessment.
