A brave Texan helped chase down the shooter and save countless lives.

Via the Washington Post:

Johnnie Langendorff stumbled into the crossfire — a total accident.

Sunday morning was all routine until then. Langendorff — a lanky Texan with a fuzzy chin beard and the long horns of a bull’s skull tattooed across his neck — had breakfast. Then he was driving his truck on the dusty back streets to his girlfriend’s house nearby. When he approached the First Baptist Church of Sutherland Springs, he noticed something odd.

As he passed the churchgoers’ cars parked around the white wood front of the building, he saw that one vehicle’s engine was running. It was a pearl-colored SUV, a Ford Explorer, he said. The driver’s door was open. A man clad all in black was walking toward the vehicle with a pistol. He was trading shots with another man holding a rifle.
