A Wayne High School Spanish teacher accused of sex crimes against a minor spent Thanskgiving night in jail.

Kelsey Hartmann, 27, was being held Friday night in the Montgomery County Jail. She faces three felony counts of sexual battery involving a minor.

The charges filed made reference to Hartmann’s role as a teacher, and indicated the minor involved may be a student at Wayne. Police declined to comment on further details in the case.

Hartmann, a married Centerville resident, was arrested Wednesday night in Huber Heights and was being held Friday on $75,000 bond. She is scheduled to appear in court Monday.

The charges carry a possible prison sentence of one to five years, and a $10,000 fine.

Hartmann is a Spanish teacher in her fourth year at Wayne High School, according to Huber Heights City Schools Superintendent Sue Gunnell.

Gunnell said the school district is cooperating with police and encouraged anyone with information about the investigation to do the same.

“We’ve been made aware of the investigation and the charges, and are putting (Hartmann) on paid administrative leave, effective immediately,” Gunnell said Friday. “We also are directing her to have no contact at Wayne High School during the investigation. We are in the process of identifying a substitute for Monday.”

Gunnell said she also would notify the Ohio Department of Education about the investigation, per protocol.

“We are making sure we are doing our due diligence,” she said.

Hartmann would have had to pass several criminal background checks to teach at Wayne, per Ohio law. She reportedly had no prior criminal history.

Hartmann’s family and Huber Heights police declined to comment Friday.
