A gunman opened fire at a crowded outdoor mall Saturday, killing at least eight people – before being killed by a hero police officer.
The shooting happened at the Allen Premium Outlets in Allen, a small suburb north of Dallas – and saw at least seven others injured.
Dashcam footage shows the moment the gunman, dressed in full SWAT garb, pull up to the outdoor outlet before opening fire on unsuspecting civilians, using an AR-15 to mow down a crowd
