Monday, Audrey Hale shot and killed six people, including three children, at The Covenant School in Nashville, Tennessee. Police have published images of the three firearms she carried.

Hale, 28, fired multiple bullets inside the private Christian institution, including at police officers, before authorities shot and killed her, Metro Nashville police said Monday night, preventing further bloodshed.

The police released photographs of the three firearms they recovered at the crime site.

According to the photographs, two firearms are assault rifles, and one is a pistol.

On the guns were stickers and writing, including "Hellfire" and "Aiden" – an online alias used by Hale.

Hale fatally shot Evelyn Dieckhaus, Hallie Scruggs, and William Kinney, all nine years old, custodian Mike Hill, substitute teacher Cynthia Peak, and school principal Katherine Koonce, both sixty-one years old.

Police say the former student prepared a comprehensive manifesto outlining his plans to assault the Religious school.

Police are investigating if Hale's transgender identity had a factor in the shooting or was related to the motive.
