Dean Schiller had just left a Colorado supermarket after shopping last year when he heard gunshots and saw three people lying face down. The independent, part-time journalist, began livestreaming on his YouTube channel, before officers arrived, and later refused dozens of police orders to move away.
He would later learn that a friend who worked at the store was one of the 10 people killed inside the King Soopers store in the college town of Boulder. The suspect, Ahmad Al Aliwi Alissa, 23, is accused of killing customers, workers and a police officer who rushed into the store to try to stop the March 22, 2021, attack.
