Conservative political commentator Steven Crowder posted photographs of three pages which he alleged are part of a manifesto written by the now-deceased Audrey Hale, who killed six people inside the Covenant School with a firearm in Nashville, Tennessee, back in March. An officer killed Hale as she continued opening fire on the second floor of the building.

"The MNPD is in communication with the Metropolitan Department of Law as an investigation, begun this morning, continues into the dissemination of three photographs of writings during an on-line discussion about Covenant School. The photographs are not MNPD crime scene images," the statement reads.

Authorities confirmed they discovered a manifesto written by Hale in which she had allegedly planned the attack for several weeks. Following the shooting, authorities obtained the manifesto, which is under an ongoing investigation by the FBI's Behavioral Analysis Unit (BAU). -Daily Caller

And while the MNPD wouldn't confirm the authenticity of the writings, Fox Nashville did.
