A former school nurse in Federal Way has been found guilty of sexual misconduct with a minor and must register as a sex offender, according to King County Superior Court documents.

Mark David Glenn, 52, of Auburn, was charged with third-degree child rape, second-degree sexual misconduct with a minor and communication with a minor for immoral purposes on Jan. 8, 2020, in King County Superior Court.

On July 16, Glenn was sentenced for one count of second-degree sexual misconduct with a minor, which is a gross misdemeanor in Washington state. He was also sentenced to 364 days in jail, which has been satisfied with electronic home detention, according to sentencing documents.

As a result of the verdict, Glenn must register as a sex offender for the next 10 years.

Glenn was employed by a third-party agency as a nurse with the Federal Way Public Schools district from Dec. 2018 through Sept. 2019. During his time with the district, he worked at 20 different schools, including elementary and middle schools as well as four of the district’s high schools.

The school nurse’s office is where Glenn met with each of his three victims and where his alleged sexual misconduct occurred, charging documents stated.

In Oct. 2019, the district was made aware of Glenn’s sexual contact with a 15-year-old student that began the prior spring. In March 2019, Glenn began to spend time in the nurse’s office alone with the student, where she said he made sexual comments and complimented her appearance, the documents state. On several occasions, Glenn allegedly touched the girl inappropriately, had her sit on his lap and asked if she could touch him.

While communicating with the girl on Kik, a messaging app, Glenn allegedly sent the victim a photo of his genitals and a video of him masturbating, asking for the girl to send him a sexually explicit video in return, to which she declined.

In the spring of 2019, Glenn picked up the girl and parked by a trailhead near a Federal Way water park. He then began to rape her while also touching himself, the charging documents stated.

While working at Todd Beamer High School, Glenn asked a second victim — a 17-year-old girl — inappropriate questions about her body and asked her to remove her pants while the girl was in the nurse’s office for a minor injury.

A 16-year-old girl, the third victim, also said Glenn touched her inappropriately multiple times.

Glenn pleaded not guilty on Jan. 23, 2020, but was placed back in custody on Feb. 29, 2020, after he allegedly threatened to carry out a mass shooting, the Mirror previously reported.

In Dec. 2020, Glenn lost his nursing license from the Washington State Department of Health.
