The teen who allegedly shot several fellow students at Wilmer-Hutchins High School in Dallas on Tuesday has turned himself in to police.

The suspect, 17-year-old Tracy Haynes, turned himself in at about 9:30 p.m. with the assistance of Urban Specialist, a community group dedicated to violence prevention and gang intervention. A family member reportedly reached out to the group on behalf of the suspect.

Haynes is currently being held at the Dallas County jail with a bond of $600,000. He is charged with “aggravated assault mass shooting.”

The shooting occurred just after 1 p.m. in a classroom at Wilmer-Hutchins High School, as previously reported by The Dallas Express. At least four people were injured, three of whom were shot, according to Dallas Fire-Rescue. All four were hospitalized.

Three of the injured are between the ages of 15 and 18, but information on the fourth person is unavailable. None of the injuries was reported to be life-threatening.

Classes at the campus have been canceled for the remainder of the week, but Dallas Independent School District Superintendent Stephanie Elizalde says mental health clinicians will be available to help students or faculty.

“Quite frankly, this is just becoming way too familiar, and it should not be familiar,” said Elizalde, per CBS News.

Last year, a shooting at the same campus injured one student. In the April 12, 2024, incident, the shooter was able to bring a gun into the school despite the use of metal detectors, and a later investigation revealed that bag-check policies had not been followed.

However, in the most recent shooting incident, DISD police officials say that all security procedures were followed.

The gun did not come through “during regular intake time, so it was not a failure of our staff, of our protocols, or of the machinery that we have,” said DISD Assistant Chief of Police Christina Smith, per CBS News.

Police have not released any details about the suspect’s motive or the events that led to the shooting, and they are still investigating how the shooter was able to bring a gun on campus.
