A former Rochester High School teacher will be arraigned Friday on charges that she sexually assaulted two students.

Kathryn Houghtaling, 26, is facing six counts of third-degree criminal sexual conduct, felonies punishable by up to 15 years in prison.

The alleged crimes occurred in November and December, Oakland County Chief Assistant Prosecutor Paul Walton said. He said at least one happened in a vehicle.

Rochester Community Schools Superintendent Robert Shaner said in a letter sent to parents Thursday that district officials fired Houghtaling Tuesday after learning about and investigating the allegations.

Houghtaling did not return messages left by the Free Press. No defense attorney is listed in her court file.

Houghtaling, who lives in Sterling Heights, taught physical science. Walton said while both victims attend the school, only one had Houghtaling as a teacher.

Shaner said the alleged crimes happened during after-school hours, and that student safety is a top concern. He also said the district is cooperating with law enforcement.

"Our support staff of counselors, social workers and psychologists are available to provide ongoing support for students and staff who are struggling with processing this disturbing information," he wrote.

Houghtaling previously taught in Pontiac, Walton said.

Her arraignment is scheduled for 10 a.m. in 52-3 District Court in Rochester Hills.
