DES MOINES, Iowa (AP) — The bishop of the Des Moines Diocese has placed a former southwest Iowa priest on indefinite administrative leave after finding a decades-old allegation of sexual abuse of a minor was credible. The diocese said in a news release on Monday that Bishop Richard Pate has placed the Rev. Howard Fitzgerald on leave while the matter is forwarded to the Vatican. The Daily NonPareil reports Fitzgerald has served at several locations in southwest Iowa – most recently at Our Lady of the Holy Rosary in Glenwood from 2011-13. He also served at St. Albert High School from 1978-83 and at St. Peter’s Church and St. Francis Worship Center from 1986-90.

While on leave, Fitzgerald can’t function publicly as a priest. Pate also has asked him to not wear clerical garb. During the investigation, Pate had asked Fitzgerald to step aside from his responsibilities at St. Thomas Aquinas Parish in Indianola, Immaculate Conception Parish in St. Marys and at Simpson College.

Pates says he’s apologized to the victim. Officials say they have notified local law enforcement where the abuse allegedly occurred.
