Police discovered a suicide note, guns and bullets belonging to Audrey Hale, the person who perpetrated the mass shooting at a Nashville (Tennessee) elementary school, during a search at her home, authorities said.
The record also revealed that Hale turned 28 on March 24, three days before the attack on the private Christian school.
The Metropolitan Nashville Police Department released a list of 47 objects or groups of objects that belonged to Hale, including a newspaper, two cartridge shotguns, cell phones and laptops.
