Steve Niedzwiecki was fired from his teaching position at a charter school in West Haven.
A judge in the Second Judicial District ruled there was enough evidence following a preliminary hearing in Farmington.
Niedzwiecki was charged with eight counts of forcible sodomy, two counts of forcible sexual abuse and attempted rape.
Niedzwiecki was a former teacher and basketball coach at Quest Academy and Jefferson Academy. He was terminated from his teaching position at Quest Academy after he was charged in December.
The victim says she befriended the teacher and worked on a project together. But according to the probable cause statement, the girl and the teacher were trading emails and text messaging. In court she testified that their relationship turned physical and became sexual. She claimed Niedzwiecki promised to marry her after their relationship turned sexual.
"He was a trusted teacher, a coach and was very manipulative," said the victim's aunt Kathy Carver.
Her family became aware of the relationship when she asked permission to date him. But her parents refused noting the age difference. She says they no longer dated after that. She testified in court that Niedzwiecki was trying to develop another relationship with another younger girl and notifed her LDS bishop.
"She wanted to make sure it doesn't happen to anyone else," says Carver.
Niedzwiecki will be arraigned in June and is out on bond.
