The suspects in the shootings at a Uvalde, Texas, elementary school and a Buffalo, New York, supermarket were both just 18 when authorities say they bought the weapons used in the attacks.

Video released from body cameras captures the chaos deputies encountered when they arrived at the scene of a mass shooting outside a Southern California bar in 2018.

In addition, Barrett's accidental shooting of Helus was justified and not criminal, the report found. The report includes edited video from security footage and officer vest-worn cameras. Long is seen waiting in a back office of the bar and watching on video monitors as Helus, Barrett and Espinoza arrive. According to the report, Long fired 61 rounds over about 20 minutes before killing himself. The district attorney's investigation is the first official report to be released on the shooting.
