The student’s mother told Killeen police on Feb. 14, 2014, that she found text messages that were “sexual in nature” and several photos of two people having sex on her daughter’s phone, an arrest affidavit said.

The student, 16 at the time, told police she began having sexual relations with Caines in September 2013, sometimes in Caines’ classroom at Killeen High School. The “continuous sexual relationship” lasted about nine months, according to a Killeen Police Department news release.

Police later found the same images and text messages between Caines and the student after executing a search warrant on Caines’ phone.

Killeen Independent School District officials placed Caines on administrative leave on Feb. 14, 2014, but was later fired, the Killeen police news release said.

Killeen police arrested Caines on June 18.

Caines’ sentencing hearing is scheduled for Sept. 8, according to the Bell County District Attorney’s Office.

A plea deal would limit his maximum sentence to 10 years and require him to register as a sex offender, the Daily Herald reported.
