Ashley Blumenshine, an Illinois high school teacher, was in jail Wednesday, charged with having sex with a 16-year-old student.
Blumenshine, 27, was arrested behind a Kohl's department store in Plainfield, Ill. on Tuesday. Police say they caught her in a car with a 16-year-old boy and determined that they'd had sex shortly before the officers arrived.
Blumenshine's attorney said she is innocent, reports CBS affiliate WBBM.
"The person in the back was partially unclothed," said Plainfield Police Chief William Doster of the 16-year-old boy.
Police noticed two vehicles in the parking lot were sitting much farther out from the store than other vehicles in the lot.
On Wednesday, the Will County State's Attorney's office charged Blumenshine with aggravated criminal sexual abuse.
"They made certain statements to the officer that led them to believe that that's what went on," Doster said. He said the affair appears to have been going on for a month or so.
CBS affiliate WBBM's Susanna Song reports that Blumenshine has taught dance and physical education at Plainfield North High School for four years.
"Our first priority is always the safety and security of our students," said Tom Hernandez, Director of Community Relations for District 202.
When asked if Blumenshine would be allowed to teach while out on bond, Hernandez said, "At this point, she is not in the building." He says a substitute will take over Blumenshine's classes at Plainfield North High School.
The school also provided students with counseling.
