The parents thought 28-year-old Audrey Hale “should not own weapons” and wrongly believed Hale had only owned one gun, which was sold, according to John Drake, the Nashville police chief. But the shooter had legally purchased seven guns at five local gun stores, Drake said, and on Monday morning used three of them to attack the school Hale once attended, killing three small children and three adults.
While the attacker left behind what Drake called a “manifesto,” he said investigators are still trying to determine what could have motivated the massacre at the Covenant School, an academy within a Presbyterian church that averages about 200 grade-school students.
