A former New Berlin West High School teacher was charged Friday with two counts of sexual assault of a student.

Sara Domres, 28, of Sullivan, was fired in January after an internal investigation. Each count carries a maximum sentence of three years in prison plus three years of extended supervision and up to a $10,000 fine.

At her initial court appearance Friday, Domres pleaded not guilty, waived a preliminary exam and was released on $1,000 bail. Her next court date was set for May 4.

According to the criminal complaint:

The student said he had been in Domres' English class as a sophomore in the 2014-'15 school year, became friends with Domres and began texting her frequently. Between Apri1 2015 and January 2016 the two exchanged more than 1,100 messages.

That led to an incident of sexual intercourse in Domres' car at a park-and-ride lot on Moorland Road in New Berlin last July. The victim told investigators he was 16 at the time.

Then in October, after he had turned 17, he had sex with Domres at a Motel 6 in Brookfield. Investigators found evidence that the boy's phone had been connected to the motel's Wi-Fi on the same date the motel records showed Domres had reserved a room with a single bed and paid in cash.

According to her Facebook page, Domres got married in August.

New Berlin Superintendent Joe Garza sent a letter to parents Friday informing them of the charges. In a statement, Garza said, "The details of the allegations against our former employee are troubling, disappointing and incomprehensible."

Domres is the second teacher facing charges of sex with a student in Waukesha County in recent months.

In December, April M. Novak, 30, of Sussex, a former Menomonee Falls School District teacher, was charged with sexually assaulting a 16-year-old student. She is due in court April 15.
