Toni Ann Reiboldt, 43, admitted to the charges of sending nude pictures and video of herself to at least four boys, and raping another by having sex with him. The admissions were part of an expected guilty plea entered in Benton County Superior Court Wedesday.

Reiboldt, who taught at Horse Heaven Hills Middle school in Kennewick for a number of years, came into focus last summer.  Investigators began to hear rumors of a video circulating via the social media platform Snapchat, during the late spring.

After obtaining a copy, police identified the subject as Reiboldt.  She resigned from the school district in July 2016.

One of the teen boys, who were all under 16, said Reiboldt was his physical education teacher. She reportedly attempted to get at least two of the boys to send her similar pictures. In January, officials learned that she had sex with one of the boys after a followup interview with the victim, according to the Tri-City Herald.

With her guilty plea, a sentencing hearing is expected to be scheduled soon.
