Two 38 revolvers. He killed almost twice as many people as Jared Loughner did with a 33 round glock 9mm magazine. Imagine that.
Illegal ownership as well, he was 24 and you have to be 25 to own a firearm in Brazil.
So prohibited possessor by their ridiculous firearm laws, using a weapon that was legal under their ridiculous caliber laws and still killed 10.
Gun control only favors criminals.
