More arrests are possible for a horrific attack at Sinaloa Middle School in Novato. Two girls were beaten during lunchtime last Friday and parents want answers. They packed the library last night after some of their own children were taken into custody. Police say several students were involved. They explained officials got word of an attack and staffed extra administrators and private security guards, but didn’t notify police or request officers. The district now plans to have teachers keep classrooms open at lunch for kids to feel safe.
