A Newark priest has been put on leave after he was accused of sexual abuse of a minor, which was alleged to have happened in the 1990s.

The Rev. Dean A. Mathewson, 77, was placed on leave by the Roman Catholic Diocese of Columbus on Monday.

Mathewson is accused of sexually abusing a minor while he was serving at St. Francis de Sales in Newark in the early 1990s.

The diocese said it got the report of this abuse on Jan. 19, according to The Catholic Times, a publication of the diocese, and that the report had already been given to Newark police.

The Newark police said they are investigating the case and that the survivor was between 12 to 14 years of age at the time of the alleged abuse. Police also said the diocese has been cooperative.

Mathewson, who could not be reached for comment, was notified of the allegations against him on Monday and placed on leave as the diocese investigates whether or not the allegation is credible.

If the diocese review board determines the allegation is credible, his name will be added to a list of 52 other clergymen who have served in the diocese and been “credibly accused” of priest sexual abuse of a minor in the eyes of the diocese.

The list, first with 34 clergy named, came out in March 2019 on the heels of the Pennsylvania grand jury report that revealed more than 1,000 victims of alleged abuse by more than 300 priests over 70 years. The report’s release spurred public pressure for dioceses across the country to release such lists telling people which priests were believed to have been abusive to children in their areas.

The Diocesan Board of Review for the Protection of Children, formed in 2003, determines the credibility of accusations using eight factors and will be convened soon, according to the Catholic Times story.

“If an allegation is determined to be credible, the Diocese of Columbus will execute the necessary judicial and administrative processes,” the Times story reads. “A determination of credibility is never to be considered proof of guilt.”

The diocese is working to notify people in the diocese and offer more information to parishioners.

Mathewson had a varied list of assignments in Greater Columbus since he began serving in 1973.
