A former Tompkins High School basketball coach and teacher has been charged with having an improper relationship between an educator and student.

Robert Ownby resigned during the criminal inquiry, the district said.

The charge is a second-degree felony. If convicted, Ownby would face jail time between two and 20 years and a fine of up to $10,000, according to the Texas Penal Code.

“The safety and security of Katy ISD students and staff is the district’s top priority,” the district said in a statement. “Whenever the district is made aware of an allegation, personnel work swiftly with law enforcement and other agencies to ensure a thorough investigation and resolution to protect the safety and well-being of all students.”

In a letter to parents sent Wednesday, Tompkins principal Mark Grisdale said Ownby has not been on the Tompkins campus, 4400 Falcon Landing Blvd., since the investigation began.

“The district takes these types of allegations very seriously and is fully cooperating with law enforcement and other agencies,” Grisdale said. “Providing a safe and secure learning environment is our top priority, and we will always act swiftly when that is compromised. Students, staff and community play an important role in keeping our school safe by reporting potential threats or safety issues.”

Grisdale said parents can report information to school administration, law enforcement officials, or use the Katy ISD app SpeakUP to anonymously report tips.
