A Canadian Hispanic uses a handgun he brought with him on a flight from Canada to shoot Canadians while they collect their luggage in an American airport.
Sounds like the solution to a game of Clue.
The report says the guy was born in NJ, though NJ isn’t much more permissive than Canada with regard to firearms.
Did the flight originate in Canada or maybe Alaska?
He could probably check a handgun into his luggage in Alaska, but I doubt it’s possible in Canada.
