In the late 1980s a pedophile with multiple convictions, Samuel David Allen, began attending services at HTC. He abused children at the cathedral before being sent back to prison for molesting a child at his place of work.
Three families from the parish sued HTC, among others, and received settlements on behalf of four children who were injured by Allen. The lawsuits filed all alleged that the priest at the time, Father George Sondergaard, knew of Allen‘s record and was negligent in his duty to supervise Allen while he was on church property. The defendants acknowledged in court documents that children were hurt by Allen at HTC, although they did not admit liability.
