In BC Supreme Court, five members of the United Nations gang and their associates have pleaded guilty to conspiracy to murder the Bacon brothers and other members of their rival "Red Scorpions" gang.
Jonathan Bacon was gunned down outside a Kelowna hotel in 2011.
Jamie Bacon is waiting to go to trial on the Surrey Six mass murder case.
The guilty pleas come four years after the first charges were initially laid, all connected to the ongoing gang and drug war that gripped Metro Vancouver in 2008 and 2009.
Today's guilty pleas are the culmination of police investigations into activity at the height of the 2008-2009 gang war in the Lower Mainland.
Police starting looking into the rapidly expanding criminal activites of the U-N Gang back in 2008.
Gang violence began to change, and escalate that year.
No longer did the gangsters take care of business, quietly and in the middle of the night.
This chapter of Metro Vancouver's gang saga introduced broad daylight shootings that dominated the news and outraged police, politicans and average citizens.
The investigation eventually resulted in charges against eight U-N Gang members, accused of plotting to murder the Bacons and their associates.
Police say the guilty pleas are a "big deal" and mark a significant milestone in the Metro Vancouver gang saga.
Sgt. Lindsey Houghton with the Combined Forces Special Enforcement Unit says the street battles of 2008 and 2009 played out in broad daylight and put members of the general public at risk.
"And that was, you know, evidenced when you saw all the chiefs of the major police agencies and departments from around the Lower Mainland, standing shoulder to shoulder and declaring that we were in the midst of a gang war."
He says that was an unprecedented admission from police.
