HOUSTON -

A former Spring Branch ISD teacher has pleaded guilty to having an inappropriate relationship with a student.

Kathryn Murray pleaded guilty to improper relations with a student and sexual assault of a child.

Last year, Murray was charged after investigators learned about her relationship with a 15-year-old boy who she was supposed to be tutoring.

Investigators say the former Memorial Middle School teacher had several sexual encounters with the boy.

Sentencing is set for January 31.
