Alvin ISD released the following statement: "Alvin ISD makes the commitment to keep our parents and community informed regarding all matters that have implications for the safety and security of our students. Although we have limited information at this time, we feel it is appropriate to ensure that parents are aware of the events that have taken place over the last couple of days. On Friday (12/15) afternoon, Alvin ISD received notification that the Brazoria County District Attorney was conducting an investigation based on reports of an inappropriate relationship between a student and an Alvin ISD police officer currently assigned to Manvel Jr. High. Upon receiving this report, Alvin ISD immediately expressed a willingness to assist with the investigation in any way possible. As the investigation was active and ongoing, Alvin ISD officials received limited information; however, the officer under investigation was immediately placed on administrative leave to ensure there was no additional interaction with students. Over the course of the weekend, Alvin ISD received notice that Officer Terry Tennard had been arrested on charges of sexual assault of a child."
Alvin ISD Superintendent Dr. Buck Gilcrease expressed, "Should these allegations prove to be accurate, the sense of violation, sadness and anger is almost immeasurable. Communities place a great deal of trust both in educators and law enforcement officials. If, as reported, this individual has violated the public's trust, Alvin ISD pledges to assist the County with the ongoing investigation and full prosecution available under the law. Alvin ISD is currently in contact with our attorney regarding formal termination. I make the commitment to our parents, to our students, and to our community that all available resources will be used to ensure this type of activity does not occur in the future."
