It’s been over two years now since the horrific mass shooting at the Covenant School in Nashville that killed six people, including three 9-years old students at the private Christian school as well as three staff members.

A summary of the police investigation, released two years after the attack, found that the shooter had spent years planning the violence and covering up mental health problems.

Just over two years after three children and three staff members were killed at the Covenant School, the Metro Nashville Police Department closed the investigation believing the shooter's primary motive to be notoriety.
