Iowa school shootings: Family says US teen who killed fellow sixth-grader was ‘tired of bullying’

17-year-old Dylan Butler fatally shot a fellow sixth-grade student and injured five others before taking his own life. Reports suggest that Butler had planned to harm more individuals, but the shooting occurred before the start of the school day, limiting the number of potential victims. Described by his family as "the kindest person ever," Butler had been grappling with relentless bullying. Despite his quiet demeanor, the family claims that school officials failed to address the issue, pushing Butler to a desperate and tragic act.
