Five men found bound with note apparently from drug cartel alluding to ‘mistakes caused by lack of discipline’

Five men who purportedly carried out the attack on four Americans last week have been found dumped on a street in the city of Matamoros, with an apology note claiming to be from the fearsome cartel that controls much of Tamaulipas state.

The five men were discovered with their hands tied, shirts pulled over their heads and bare chests to the pavement. Nearby, a note in black marker read: “We’ve decided to hand over those involved and directly responsible in the events who acted at all times under their own free will.”
