Shortly after midnight, one year ago today, shots rang out. This year, at the same time, it was songs of praise and throbbing gospel music – all done to mark the first anniversary of the multiple shootings at the Youth With A Mission campus in Arvada, and, later that morning, at New Life Church in Colorado Springs.

“This is Tiffany's first birthday in heaven, and Phil's first birthday in heaven,” said Peter Warren director of YWAM, a youth missionary organization, to a crowd of nearly 150 who jammed into the fellowship hall on the campus for a midnight service.

The Arvada police were there. Last year they were first to come upon the horrific scene, where Matthew Murray, a disaffected former wannabe missionary, had opened fire on his former fellow students, killing Tiffany Johnson and Phil Crouse. He wounded Dan Griebenow and Charlie Blanch. Earlier on this Monday night, 14 police officers had jogged the three-plus miles to the YWAM building in the snow and cold – identical weather to last year – as a sign of solidarity with YWAM. In this past year, they have become like family.

“I got to know Phil and Tiffany in a completely different way,” said Arvada Police Chief Don Wick, one of those who spoke. Tiffany wanted to change the world, Wick said, “now we have to change the world for them. We don't want to see this happen again.”

As for Phil, he was a woodworker, just like Wick, who told the crowd, “When I work in my shop, I think about Phil and what he's doing.”

Murray's parents, Ron and Loretta, were there. The crowd embraced them. Before the service started, one of the young men their son had wounded, Charlie Blanch, now 23, came over to clasp the Murray's hands and draw them into a small circle of prayer for just the three of them. Later, a large crowd formed around the Murrays to pray for them and their loss of their son, who killed himself at the end of his killing spree.

Tiffany's mother, stepdad and sister were there. And among the sea of young people, many friends of the victims. When the video clips of “Tiff” and Phil began, many wept.

Then people stood to remember them.

Phil, the house builder who used to live in Alaska, hung out with native kids and swung a mean hammer.

“He had a special relationship with that tool,” one of his friends said, to laughter.

Tiffany had a huge heart, and wanted to change the world . Her favorite saying -- big on meaning if not grammar -- was , “I'm going to change the world by loving on people.”

Her saying was memorialized, earlier that afternoon at yet another anniversary observance, when the Arvada police unveiled a commemorative plaque to honor the victims.

In tears, Rachel Warren, a close friend of Tiffany's, told the crowd that the moment at the unveiling of the plaque held special meaning.

“It brought so much joy – it's funny saying that, because I'm crying,” Warren said. Seeing the impact on the police and the crowd – all the people Tiffany had touched -- she said she wanted to tell Tiffany -- “I wish you could see the fruit of your life... it shows a reflection of God.”

Tiffany said she wanted to go into the hard places to show her love, Warren added.

“And she did.”
