The student died at the school, and the officer was taken into surgery, authorities said. The officer – who KPD identified as Adam Wilson, a 20-year veteran – had surgery Tuesday morning and was expected to recover. No one else was injured.

It wasn't yet clear why the student brought a gun to school or why he fired at officers. An investigation by TBI is ongoing.

The shooting comes as more classrooms are reopening to students after months of remote learning during the coronavirus pandemic, which cut down the number of mass killings in the U.S. The nation has seen series of mass shootings in recent weeks, including eight people killed at three Atlanta-area massage businesses on March 16 and 10 people killed at Colorado supermarket on March 22.
