Oroville >> A physical education teacher has been arrested on suspicion of having sex with two high school students, according to the Butte County Sheriff’s Office.

Lindsay Himmelspach, 33, of Chico, was arrested Friday at Las Plumas High School and booked into Butte County Jail on two counts of unlawful sexual intercourse with a minor, two counts of communicating with a minor for purposes of committing sexual acts and two counts of communicating with a minor to commit a lewd or lascivious act, according to a Sheriff’s Office news release.

Investigators allege Himmelspach had brief sexual relationships with a male student attending Las Plumas High School and a male student attending Prospect High School, according to the release.

The alleged crimes occurred over the summer and included the sharing of nude photographs between Himmelspach and the two victims, according to the release.

Himmelspach has been teaching for 10 years and has worked at Oroville High School and Las Plumas High School, according to the release. She has been placed on paid administrative leave by the Oroville Union High School District.

Sheriff’s investigators met Friday with Corey Willenberg, the district’s superintendent, who reported a possible inappropriate relationship between a high school teacher and students, according to the release. The information surfaced following a message left at Las Plumas High School by an anonymous caller.

Himmelspach graduated from Pleasant Valley High School in 2000 and went on to play four years of softball at Chico State University.

Her bail was set at $90,000.

Anyone with information regarding the case is asked to call sheriff’s detectives at 538-7671.
