A former Menomonee Falls teacher charged Tuesday with sexually assaulting a 16-year-old student told investigators she knew that the boy was underage, but that the relationship was mutual and that the two had "very strong feelings for each other," according to criminal complaint filed in Waukesha County Circuit Court. April M. Novak, 30, of Sussex faces 12 felony counts of sexual assault of a student by school staff. If convicted, she could face up to six years in prison and a fine of up to $10,000 on each count. Novak remained in the Waukesha County Jail on $100,000 bail Tuesday. Court Commissioner Laura Lau ordered her to have no contact with anyone under the age of 18, including her own children. According to the complaint, Novak is accused of engaging in sexual intercourse and oral sex with the teen in her classroom numerous times since mid-October. The boy told investigators that the two had agreed not to tell anyone about their sexual relationship.
