Fr. John C. Slown was ordained a priest for the Diocese of Joliet in 1959. Throughout Fr. Slown’s priesthood there were many complaints of his excessive drinking and sexual abuse of children and it is reported that at one point he was sent for treatment at Servants of the Paraclete, an institution known for treating priests accused of child sexual abuse. In 1983, Fr. Slown was convicted of child sexual abuse perpetrated at St. Irene and was subsequently defrocked. It is believed that Fr. Slown was removed from ministry in 1986 due to multiple allegations of child sexual abuse. Fr. Slown purportedly claimed, in 2002, that he left ministry because of alcoholism. In 2003, five brothers filed a lawsuit which named Fr. Slown and two other priests and accused them of sexually abusing them for six years when they were children at St. John the Baptist. Fr. Slown was named on the Diocese of Joliet’s list of “Diocesan Priests with Credible Allegations of Sexual Abuse of Minors Made against Them While Serving in the Diocese of Joliet” with “Substantiated Allegations.” As of 1987, Fr. Slown was reported to be living in Colorado, however, his current whereabouts, status as a priest, and whether he has access to children are unknown.
