Seven mature trees growing in the quad at Maria Carrillo High School in Santa Rosa were badly damaged by vandals late Sunday or early Monday morning, said Principal Rand Van Dyke.

Five cercis western red bud trees were felled by an ax and two others were badly damaged, he said. Trash cans also were overturned.

A police report was filed and the level of damage constitutes felony vandalism, Van Dyke said. An announcement was made on campus Monday morning, asking students with any information to step forward. An email was sent to parents Monday night.

"I would say the vast majority of the students I have spoken to are very upset, chagrined, that it could be one of their own that did this," Van Dyke said.

The trees were planted more than eight years ago, he said. Damage of $400 or more can result in a felony charge.
