A former worker for the food contractor at Lambeau Field says he was frustrated because he couldn’t find a job and the rent was due.  Forty-year-old Chay Vang made a Brown County court appearance Tuesday.  He faces charges of recklessly endangering safety and criminal damage to property.  Vang told police he went to the stadium last Friday looking for the people who caused the company Delaware North to fire him.  When he saw of his former co-workers sitting in a car, he says he “lost it.”  Vang’s actions damaged five vehicles, but no injuries were reported.
