SYRACUSE - A massage therapist has admitted secretly videotaping a client as she undressed at his business.

Mark Boice of Jordan pleaded guilty Friday to unlawful surveillance in exchange for a promised sentence of one year in jail. He will be sentenced Jan. 11.

Boice faced up to four years if he had been convicted at trial.

Police said Boice made the secret recording at his home-based business, Natural Health Therapy, in March or April 2008.

Boice, who's 53, will be required to surrender his massage therapy license and agreed to never apply to have it reinstated.

Boice's plea also satisfied an additional charge of possessing a sexual performance by a child. Police said they discovered child pornography videos on Boice's computer.
