LOCKPORT – Hollis Stewart of North Tonawanda admitted Thursday in State Supreme Court that he had pornographic images of children on his cellphone in April.

Stewart, 38, of Main Street, pleaded guilty to a felony count of possession of a sexual performance by a child. As a second-time felon, he faces mandatory prison time.

Justice Richard C. Kloch Sr. could sentence Stewart to as long as four years behind bars when he returns to court Aug. 15. In the meantime, Stewart remains in the Niagara County Jail in lieu of $10,000 bail.
