Unanswered Questions Linger in Aftermath of Nashville School Shooting

More than two weeks after the Nashville Christian school shooting, investigators have not yet identified a clear motive in the attacker’s journal writings, and authorities have not provided any details publicly to back up their early suggestion that the shooter may have felt resentment toward the school. One of Tennessee’s top law enforcement officials said in a recent meeting that the writings of the 28-year-old shooter, Audrey Hale, appear to be ramblings and indicative of a mental health struggle. A federal law enforcement source verified to NBC News that no direct motive has been established in the investigation and suggested that the driving force of the attack was similar to previous school shootings in which the assailant was drawn to other mass killers.
