Eight Tomales High School students were suspended from classes last week after an investigation by the Marin County Sheriff’s Office found they were part of a larger group that vandalized the school’s football field in February, aided by alcohol. In the early hours of Saturday, Feb. 22, roughly a week after the athletic field received a new layer of grass, 14 people broke through the locked gates and spun donuts across the field. School officials estimate the damages at $20,000. Some of the revelers were over 18 and spent a night in jail; they will face further consequences when they go before a county judge on March 17. The rest, who are underage, were fined and ordered to take after-school classes, help repair the field and fulfill community service hours beyond the usual graduation requirement.
