DALLAS — The student who shot four students when he opened fire at a Dallas high school this week was in and out of the building in less than two minutes and is believed to have been targeting a specific student, the school district police chief said Thursday.
The 17-year-old suspect was able to enter Wilmer-Hutchins High School, which has metal detectors at its entrance, at 1:01 p.m. Tuesday when another student opened a locked side door, Dallas Independent School District Police Chief Albert Martinez said.
The suspect was taken into custody several hours after the shooting. He was remained in jail on Thursday on a charge of aggravated assault mass shooting.
Martinez said it’s believed there was “a dispute taking place,’’ but police do not know what led to the shooting.
Martinez said they are looking into “how deep’’ the culpability is of the student who opened the door.
Four male students were shot and were taken to hospitals, according to officials. Martinez said all of them are expected to make a full recovery.
