A woman who’s been teaching middle school for decades in Butte County has been arrested on suspicion of having sex with an underage former student. Gridley Police say they began investigating on October 10th after sexually explicit photos had been circulating among students that showed Michelle Solis engaged in sexual activity with boy under the age of 16. Solis has been a teacher at Sycamore Middle School in Gridley for 20 years. She was arrested Monday. Police are encouraging parents to talk to current and former students to determine if Solis had sexual relations with any other children.
