Wisconsin school shooter received messages from man accused of plotting his own attack

The shooter who killed a student and teacher at a school in Madison brought two guns to the school and was in contact with a man in California who authorities say was planning to attack a government building. According to authorities and court documents, a California judge issued a restraining order Tuesday under California’s gun red flag law against a 20-year-old Carlsbad man. The order requires the man to turn his guns and ammunition into police within 48 hours unless an officer asks for them sooner because he poses an immediate danger to himself and others. According to the order, the man told FBI agents that he had been messaging Natalie Rupnow, the Wisconsin shooter, about attacking a government building with a gun and explosives. The order doesn’t say what building he had targeted or when he planned to launch his attack. It also doesn’t detail his interactions with Rupnow except to state that the man was plotting a mass shooting with her.
