From the New York Post:
Police have not yet released information related to the motive, but said the school — not specific victims — was targeted.
Swope told The Post that Hale had “looked at” two other schools, both public, before deciding “the security was too great to do what she wanted to do.”
“So she chose a private Christian school, for, probably the reason is that the security is a whole lot less,” he went on. . . .Stephanie Pagones, “Nashville shooter Audrey Hale’s manifesto to be released after FBI review: official,” New York Post, March 29, 2023.
