Kentwood High School teacher faces sexual misconduct charge

Placed on administrative leave; allegedly had relationship with student 5 years ago

A Kentwood High School teacher faces a first-degree sexual misconduct with a minor charge for an alleged relationship with a student from 2017 to 2019.

King County prosecutors charged Steve A. Bilvais, 55, on Aug. 9. He pleaded not guilty on Aug. 22, according to the King County Prosecuting Attorney’s Office. He is scheduled to return to court Sept. 25 for a routine pre-trial hearing.

“The employee is on administrative leave,” according to a Aug. 23 email sent to Kentwood families and parents by Principal Samantha Ketover.

School starts Wednesday, Aug. 28 in the Kent School District.

Bilvais allegedly abused a supervisory position with a female student who was 17 years old at the start of a relationship that reportedly went from October 2017 to June 2019, according to charging documents.

“The defendant took advantage of his position as a teacher at Kentwood High School,” wrote Deputy Prosecuting Attorney Mylla Dawson in charging documents. “He abused that position by engaging in a sexual relationship with a minor who was also a student at Kentwood. He knew that engaging in a sexual relationship with (the girl) was against the law, as he told her he could lose his job or go to jail if anyone found out about his conduct.”

A King County Sheriff’s Office detective opened an investigation two months ago after a woman called in June to report a sexual relationship with a teacher of hers from several years prior, according to charging papers. The woman claimed they had sexual intercourse over a two-year period, sometimes at his Auburn residence and other times at her former Covington residence.

A detective asked the woman why she is coming forward now about this. She said it took a long time to process the love she had for him, according to charging documents. She slowly started to realize the gravity of the situation. She started to go to therapy in February 2024 and was thinking of the “moral obligation” she had to report this since Bilvais “holds a position of power” and he “abused it.” She doesn’t want this to happen to other girls.

The woman said Bilvais was her algebra teacher her freshman year at Kentwood in 2015. She said everything was professional her first two years. Things began to change when she took a job as a babysitter for his daughter. She said they would flirt with each other at his house after babysitting.

She said the relationship went from kissing to intercourse in October 2017, according to charging documents. She said they talked about getting married and having kids.

About November 2019 their relationship ended. The woman said it was amicable and that he understood she needed to do her own things in life.

Bilvais reportedly purchased a lot of clothes for the girl as well as a necklace and ring. Detectives discovered a box of the woman’s items at her parents home that reportedly included the necklace and ring he bought her and copies of checks Bilvais wrote to her for babysitting.

The girl showed detectives photos of herself taken with Bilvais after she turned 18, according to charging papers. A few of the photos were of them kissing and posing together.

A detective tried to contact Bilvais to talk about the case by knocking on his door, calling him and leaving voicemails and a business card, but never reached him for questioning.
