Andrew Adams, KSL Newsradio For the many that called 911, the audio serves as a grim reminder of the Trolley Square tragedy and the life-or-death decisions they made that night.
Mackenzie Flanders: "It's still very vivid."
Mackenzie Flanders was speeding away in a car when she called 911.
Mackenzie Flanders' 911 call: "There was shots being fired towards us. We drove away because we didn't want to get hurt."
She tells the dispatcher about one of the toughest decisions she and her boyfriend, Rob Coleman, ever made. They chose to leave victim A.J. Walker behind, who had been shot in the head and pleading for help.
Mackenzie Flanders 911 call: "He came running towards our car, and he was covered in blood."
Rob Coleman: "We saw the boy coming down, and that's when my heart started to pound."
Mackenzie Flanders: "I can still remember the boy's face."
Rob Coleman: "He got a handprint or two on my car. It was pretty terrifying. We just saw blood coming off the back of his head."
Mackenzie Flanders: "We feel so horrible for leaving this boy."
They say they saw it as life or death for them. They chose life, but they'll always regret not stopping to help. It is something that they will never forget.
