A former Rockwall ISD middle school teacher was sentenced to 10 years in prison for sending "sexually explicit" emails to an eighth-grade student, the Rockwall District Attorney's Office said.
In addition to the emails, Marc Allison, 50, also touched the student inappropriately in class, bought her a sex toy and brought syringes to school "in attempt to draw and drink her blood," the district attorney's office said.
Allison taught at Cain Middle School until he was arrested in October 2019 after the student reported the abuse to her school resource officer.
