Hey, it's Nancy, before we begin today, I just wanted to let you know that you can listen

On New Year's Day in 2009, a triple murder at a restaurant sparked outrage in Calgary.

A high-ranking gang member and his associate were the targets, but caught in the middle was an

innocent victim, Kenny Sua. He was at the restaurant having a meal when gunfire erupted.

He was shot and killed as he ran for safety. A lot of unrelated people in the restaurant,

panicking and fleeing, and again, here's a situation where somebody just trying to be safe,

running out of the restaurant again gets shot and another innocent person is killed.

I'm Nancy Hicks, a senior crime reporter for Global News. Today, on Crime Beat,

I share the story of how one death became the tipping point in a decades-long gang war.

One that led police to great lengths to try and end the violence,

including making what some call a deal with the devil. This is part two of The Crossfire.

The triple homicide at the Bolsa restaurant brought the death toll up to two dozen

over the first seven years of war between the FOB and FK gangs. And despite the increased spotlight,

the violence wasn't slowing down. Here's Senior Crown Prosecutor Brian Holtby.

It became really a series of tit-for-tat killings. The FOB would seek revenge for a killing by the FK,

the FK would seek revenge for a killing by the FOB, and eventually by between, say,

2000 and 2009, there were 25 killings that we attribute to either the FOB or the FK.

Homicide Detective Mike Shoot has extensive experience dealing with gang members and gang

investigations. He said that over and over investigators tried to intervene to stop the violence.

We had knowledge and information at times that people were insignificant threat and were being

targeted. The rival group had a bead on somebody and were actively planning to murder them.
