A former Crete High School teacher pleaded not guilty to sexual assault charges Wednesday.
Matthew T. Hoffman, 41, of Dorchester, hasn't yet been given a trial date on two counts of second-degree sexual assault of a protected individual and one count of first-degree sexual assault.
Prosecutors originally charged him with two counts, but later added the third, which could get him the most time — up to 50 years in prison — if he's convicted.
The other two charges each carry up to three years in prison.
Details that led to Hoffman's arrest remain sealed in court records, though the complaint alleges there were two victims and that the assaults happened between June 29 and Jan. 8.
Saline County sheriff's deputies arrested him Jan. 19. He was released from jail Feb. 6 after posting $75,000 bond. He is to have no contact with anyone under 19.
Wednesday, Saline County District Judge Vicky Johnson set his next hearing in May.
When he was arrested, Hoffman was a Success Academy teacher at Crete High School. He resigned Feb. 9.
