When Devin Patrick Kelley opened fire on the congregation at the First Baptist Church in Sutherland Springs, Texas, it turned into one of the deadliest mass shootings in American history.
The gunman killed 26 people and left 20 more with serious injuries in the gun rampage just after 11.20am on November 5, 2017.
It became the deadliest shooting in a US place of worship and the fifth deadliest mass shooting to have ever happened in America.
Wearing a black face mask with a white skull, tactical gear and a ballistic vest, Kelley burst into the church and scream "everybody dies, motherf******".
He shot methodically and indiscriminately at the congregation as he marched up the centre aisle of the church, firing off 700 rounds in just 11 minutes.
Kelley paused only to reload his rifle before carrying on his murderous rampage.
Julie Workman was sitting among the congregation with her sons when Kelley opened fire.
What happened next was every parent's worst nightmare.
Julie explained: "The gunman started walking up to people individually and, at point blank, shooting people.
“He walked straight up to the centre aisle to the side where myself and my sons were at and stood there for a few seconds.
"I thought, 'I can reach out and grab his leg and jerk him back and catch him off guard'.
"I looked at my oldest son straight in the eyes and I saw the barrel of the gun go down and shoot him point blank in the back."
Thankfully, the bullet didn't kill Kris but he was left with devastating injuries.
He said: "They basically told me that my spinal cord had been nearly completely severed.
"They didn’t really ever tell me in specific terms that I’d never walk again, but they alluded to it.
"For me, a lot of it was realising what I do have. I still have my wife, I still have my baby and I still have my mom.
"The important thing is my close family are still alive."
Kris was the last person Kelley shot and Julie the last person he took aim at before former firearms instructor Stephen Willeford bravely risked his own life to stop the killing spree.
After taking cover behind a truck, he shot Kelley twice in his leg and body.
Shocked, Kelley dropped his rifle but fired back with a handgun before jumping into his car and fleeing.
Determined to stop the shooter at all costs, Willeford stopped Johnnie Langendorff in his truck and the two men embarked on a high speed chase after Kelley, giving police their location.
During the chase, Kelley made an emotional call to his wife and parents, telling them "I just shot up the Sutherland Springs church" and repeatedly saying he was sorry.
Bleeding heavily and seriously hurt, Kelley lost control of his car and smashed into a road sign.
When Willeford and Langendorff arrived he was motionless and police confirmed he died in the car from gunshot wounds, including a self-inflicted shot to his head.
Kelley, who had served in the US Air Force, had been banned from buying or owning guns or ammunition after being convicted of assaulting his wife and toddler step son.
But he had managed to buy a semi-automatic rifle lying about his criminal past and because his military convictions hadn't been entered into the national database.
Following the massacre US President Donald Trump insisted "mental health problems" not guns had been to blame.
In a press conference he said: "Based on preliminary reports, this was a very deranged individual with a lot of problems over a very long period of time.
"We have a lot of mental health problems in our country, as do other countries, but this isn't a guns situation ... we could go into it but it's a little bit soon to go into it.
"Fortunately somebody else had a gun that was shooting in the opposite direction, otherwise it wouldn’t have been as bad as it was, it would have been much worse."
However, 10 days after he shooting, Senator John Cornyn introduced a Bill that has now become law and introduces strict penalties for government agencies who don't report convictions.
