The Nashville School Shooting suspect lawfully purchased seven guns from five local businesses and used three of them in Monday's assault that killed three children and three adults.

In a Nashville School Shooting update, Nashville authorities said the suspect made weapons purchases over the last several years while living with her parents.

Nashville School Shooting suspect Audrey Hale, 28, lived with her parents, who were opposed to her owning a gun. Metropolitan Nashville Police Chief John Drake told journalists on Tuesday that they thought the attacker had one firearm and sold it, per CBS News.

As the shooter left the house on Monday morning, Hale's parents questioned their child about the contents of the red bag but were disregarded, according to a report from CNN.

The Nashville School Shooting suspect, a former student of The Covenant School, was also being treated for an "emotional disorder," but never disclosed this to authorities.

Drake also noted no "red flag" statute in Tennessee would allow police to take away a person's guns. The chief noted that officials would have attempted to seize the guns if it had been known that the attacker was suicidal or meant to harm someone else.

Hale's manifesto with the Nashville School Shooting details was discovered by authorities, but the motivation remains unknown as of Tuesday afternoon, according to Drake.

Metropolitan Nashville Police Department spokesman Don Aaron stated on Tuesday that the assailant did not specifically target any people, but rather the school and the nearby Covenant Presbyterian Church, per Fortune.

Authorities think Hale held anger over being forced to attend the Covenant School that may have caused the Nashville School Shooting.
