Wisconsin school shooter was in contact with California man plotting his own attack, court documents say

The shooter who killed a student and teacher at a religious school in Wisconsin brought two guns to the school and was in contact with a man in California whom authorities say was planning to attack a government building, according to authorities and court documents that became public Wednesday.

Police were still investigating why the 15-year-old student at Abundant Life Christian School in Madison shot and killed a fellow student and teacher on Monday before shooting herself, Madison Police Chief Shon Barnes told the Associated Press Wednesday. Two other students who were shot remained in critical condition on Wednesday.

A Southern 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.
