Nashville School Shooter Purchased 7 Guns Legally Before Attack.

The Nashville school shooter legally purchased seven firearms from five stores before the attack, killing six people, including three children. The shooter had planned the attack and had maps of the school. The parents were unaware of the shooter's access to so many guns, and the weapons were hidden from them. The assailant had been receiving treatment for an emotional disorder, which hadn't been reported to authorities. The police are investigating other possible targets, including a mall and family members.
