A 17-year-old boy has been charged with aggravated assault mass shooting after he allegedly opened fire on classmates at a Dallas high school.
Five students were treated at area hospitals for non-life-threatening injuries; three of them were wounded by gunfire, authorities said.
ABC News reports that surveillance cameras showed a student letting the suspect, Tracy Haynes, into Wilmer-Hutchins High School Tuesday afternoon through an unsecured door.
Haynes walked the hallway "until he spotted multiple male students" and then allegedly shot at them "indiscriminately," hitting five people, according to an arrest warrant affidavit.
Haynes then allegedly "approached one student who was not able to run" and "appeared to take a point-blank shot," the affidavit said.
Five students were taken to hospitals. Four were directly affected by the shooting; the fifth was treated for anxiety-related symptoms, CBS News reports. Dallas Fire-Rescue says three of the four victims were shot and their injuries are non-life-threatening. Three of the victims are between the age of 15 and 18 and one victim's age is unknown.
Classes at the high school have been canceled the rest of the week, and mental health professionals will be made available, Superintendent Stephanie Elizalde said.
