He withdrew a huge amount of money, in a manner that is only used by CIs and agents. From the article:

> A Mountie familiar with the techniques used by the force in undercover operations, but not with the details of the investigation into the shooting, says Wortman could not have collected his own money from Brink’s as a private citizen.

and

> “When you come into my branch and you want a ton of cash, then I say, you gotta give us a couple of days. We put in our Brink’s order, I order the money through Brink’s, then when the money arrives, you come back into the branch, I bring you into a back room and I count the money out for you,” the banking expert said. “Sending someone to Brink’s to get the money? I’ve never heard of that before. The reason is, if I’m the banker, and you’ve deposited your savings in my bank branch, I’m responsible for making sure the money goes to the right person. If you want this money, I’m going to verify your identity and document that. I can’t do that if I’m transferring the money to Brink’s.”

It's solid evidence that this guy is connected to the RCMP in some manner.

That kind of transfers could be also used by the Hells Angels, which is a front for the Drug cartel. It's also very likely that he withdraw his own money, using his cartel connections to get it in cash from Brink.

A government service (FBI eqivalent) using such a loose cannon as informant is likely, but paying him that much unlikely. And the rampage looks very personal, unlike other cases in the US.
