The former student who shot and killed three nine-year-olds and three adults at The Covenant School in Nashville in 2023 meticulously researched and planned her violent act for years, says a summary of the Metropolitan Nashville Police Department’s investigation.

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.

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.
