A Beaumont electrician convicted of defrauding the Beaumont Independent School District out of more than $1.2 million has had his probation revoked. Judge John Stevens then sentenced Calvin Walker to 9 ½ years in prison. Walker will not have to report to prison until after his appeal. Records show Walker has paid just over $2,000 in restitution, and spent more than $8,000 on multiple items including movies, blankets, and phone use while serving 180 days on weekends.
