At the request of law enforcement officials, a judge ordered a man, who reportedly corresponded with the shooter about a second attack, to surrender his guns.

Police have identified the shooter in Monday’s deadly attack on a Madison, Wisconsin, private Christian school as a 15-year-old female student as they investigate the latest school shooting to devastate an American community.

According to multiple news outlets, a judge issued a restraining order Tuesday to a Carlsbad, Calif., man who revealed to FBI agents that he told 15-year-old Natalie “Samantha” Rupnow he was planning to target a government building.
