Police were investigating a reported shooting Tuesday afternoon at Wilmer-Hutchins High School in Dallas, a department spokeswoman confirmed to The Dallas Morning News. Officers were dispatched about 1 p.m. to the school in the 5500 block of Langdon Road. A police call log showed 19 units at the scene.

The chief of police for the Dallas Independent School District says 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.
