A former Catholic high school teacher already accused of sexually assaulting Colorado students in the 1960s is now accused of abusing a student in Missouri.
The Survivors Network of those Abused by Priests announced a lawsuit Tuesday accusing William Mueller of using both a knife, and threats of violence, to silence the alleged victim in 1985.
SNAP officials say the abuse occurred at Vianney High School near St. Louis.
Two men accused Mueller last week of drugging them with ether, then sexually assaulting them, when they were students at the former Roncalli High School in Pueblo.
The all-boys school was owned by the Diocese of Pueblo and staffed by the Society of Mary Religious Order.
The school no longer exists.
