“Lone wolves” collaborating and frequently comparing notes.

“Youth arrested on terrorism charges had cell number for Couture-Rouleau,” by Paul Cherry, Montreal Gazette, September 10, 2015:

The teenager from western Montreal currently on trial for allegedly preparing to leave Canada to take part in terrorist activity abroad communicated with Martin Couture-Rouleau dozens of times before the latter killed a Canadian soldier in St-Jean-sur-Richelieu last year.

The now 16-year-old teenager eventually admitted he had frequent exchanges with Couture-Rouleau during a nearly three-hour interrogation with a member of the Integrated National Security Enforcement Team (INSET) and an investigator with the Sûreté du Québec on Oct. 20. He was questioned, at a youth detention centre in Laval, just hours after Couture-Rouleau used his car to run over two Canadian soldiers in St-Jean-sur-Richelieu including Warrant Officer Patrice Vincent, 53, who died in what the police quickly realized was a terrorist attack.

As the SQ investigated Vincent’s death they learned that Couture-Rouleau had a cellular phone. They then learned that the youth, who had been arrested on Oct. 17 in connection with an armed robbery at a convenience store in western Montreal, had the number for that same cellphone written down on a slip of paper found in a pair of his pants. The national security team was at the time investigating whether the youth held up the convenience store with a knife, to buy a plane ticket, possibly to fly to Syria and join ISIL
