An alleged victim of sexual abuse has sued the Diocese of Sioux City, claiming he was victimized by a diocesan priest as a young child in the late 1960s.

Samuel Heinrich said in the lawsuit that The Rev. Dale Koster sexually and physically abused him, beginning in 1968 when he was about 9 or 10 years old, and continuing through at least 1970. The alleged abuse occurred at the Our Lady of Mt. Carmel Catholic school and at the parish’s rectory, according to the suit, which was filed Wednesday in Woodbury County District Court.

Koster retired in 1996 and died at the end of May at age 94, according to his obituary. He was not among the 28 priests the Sioux City Diocese identified earlier this year as being credibly accused of sexual abuse, dating to the 1940s.

Diocese spokeswoman Susan O’Brien said in an email Friday night that she could not specifically comment on Heinrich’s allegations.
