"Iowa School Shooter's Discord Activity and Community Support After Perry Shooting"
The Iowa school shooter, Dylan Butler, appeared to express nervousness and readiness for the attack in messages on the online platform Discord just before opening fire at Perry High School, killing a sixth grader and injuring several others. His social media accounts, including Discord, are under investigation, and it's been reported that he had previously been part of a chatroom discussing school shootings. The FBI had been alerted to this chatroom in November, but it's unclear if any action was taken. Butler, who was described as a victim of bullying, was found dead next to an undetonated explosive device, and no clear motive has been established for the shooting.
