A former drama and speech teacher at Clearfield High School Tuesday pleaded guilty to two of four felony charges that he sexually abused students during costume-fitting sessions for school Christmas presentations.

Norman A. Maxfield, 44, 1273 W. 26th North, Clinton, pleaded guilty to two second-degree felony charges, forcible sexual abuse and sexual exploitation of a minor.Both carry prison terms of one to 15 years and fines of up to $10,000 and could be served consecutively, Judge Rodney S. Page told Maxfield when the plea bargain was concluded. Sentencing is set for Dec. 20.

Maxfield was originally charged with three counts of forcible sexual abuse and the sexual exploitation charge. The incidents occurred in December 1986 and December 1987 while Maxfield was fitting male 16- and 17-year-old students for costumes, according to an affidavit he signed Tuesday in court.

According to court documents, the boys were told by Maxfield to undress for the costume fitting and were fondled while the teacher uttered obscenities. One boy noticed a video camera was running, according to court records and later made off with the tape, which depicts two students being fondled.

Maxfield was a 14-year veteran teacher but resigned from the district Sept. 14, four days after the charges were filed.
