Three vandalism incidents at the San Geronimo Valley Community Center and Lagunitas School District last week spooked staff and kids enrolled in summer camps, who returned to the center’s Loft youth space on Monday to find its floors and walls covered with gobs of cleaning supplies, honey and raspberry jam. The trashing over the weekend followed a fire extinguisher sprayed in the gym last Tuesday night and spray-paint tags on the school last Wednesday. Community center officials and valley residents point to kids as the potential culprits, possibly as young as eight to 10 years old. “It’s just been awful,” said Dave Cort, the community center’s executive director. “Everybody is so bummed out, particularly the kids.” Lt. Doug Pittman of the Marin County Sheriff’s Office said officers are following up on leads, though he offered no details of the investigation. Sheriff’s reports indicate that the school district plans to install security cameras; district officials could not be reached for comment. The district incurred damages to a window screen and a couple of doors. The reports state that sometime Monday night, the vandals broke into the gym, shattered the fire extinguisher’s glass panel and sprayed extinguisher all over the floor. The next night, vandals tagged the school’s library and other buildings with “faces or something a kid would do,” using a spray canister stolen from a nearby construction site. And over the weekend, the vandals poured cleanser, raspberry jam and honey “over every step,” the floors and walls of the Loft. Though Lt. Pittman did not think it was related to the vandalism, Mr. Cort said a volunteer working with the center’s food bank in May returned midday to the parking lot to find her car windows smashed, with her purse and coat taken. “It feels like the end of the valley’s innocence,” Mr. Cort said.
