However, no reason for the shooting has been identified yet and the police said they are working to understand what led to the tragic incident. Later, in an interview with NBC, Drake said investigators believed the shooting stemmed from "some resentment" the suspect harboured "for having to go to that school" as a younger person.

The Covenant School mostly comprises elementary school-age children. The tragedy is the latest in the string of mass shootings that have sadly become common in the country.

Drake, the police chief, referred to the assailant by female pronouns and said the suspect identified as transgender.

The Tennessean newspaper reported that a police spokesperson said the suspect used he/him pronouns. Hale used male pronouns on a LinkedIn page.
