Mia had all the details on Thursday regarding the tragic school shooting in Perry, Iowa. As students at Perry High School were returning from their winter break Thursday morning, Dylan Butler, 17, opened fire, killing one sixth-grader and injuring five others (via NYT):

A gunman killed a sixth-grade student and injured five other people at a high school in Perry, Iowa, early Thursday morning just as students were arriving back to school after their winter break. 

Four of the injured were students, and one was an administrator, Mitch Mortvedt, assistant director of the Iowa Division of Criminal Investigation, said at a news conference on Thursday. One of the injured victims was in critical condition. 

The administrator was identified by Easton Valley Community School District as Dan Marburger, the principal at Perry High School, where the shooting took place. Officials did not release the names of any other victims. 

The gunman, identified as Dylan Butler, a 17-year-old student at the high school, died from a self-inflicted gunshot wound, Mr. Mortvedt said. Law enforcement officials believe he acted alone and said the motive for the attack was not yet known.

Mia noted that Butler’s social media accounts were scrubbed, but before they were deep-sixed, he was known for using “genderfluid” hashtags. Before committing suicide, Butler also set bombs in the school.
