OLATHE, Kan. (AP) — A suburban Kansas City massage therapist faces sentencing Jan. 3 after admitting that he secretly recorded video of a woman while she undressed.

32-year-old Daniel Gorski pleaded guilty Thursday to a felony count of breach of privacy. He previously worked as a massage therapist at a chiropractic clinic in Gardner, Kansas.

An investigation began in 2016 after Gorski’s girlfriend reported finding a computer flash drive containing images of women undressing or nude. Prosecutors eventually charged Gorski with crimes involving several women, but the additional charges were dismissed as part of a plea agreement on Thursday.

Gorski also pleaded guilty earlier this year in Jefferson County, Kan., to possession of child pornography.
