Mary Montana is a character in the game killer7. She is the daughter of Pedro Montana. Curtis Blackburn killed her and her brother Paul, and then brought her head with him to taunt and kill Pedro. He alludes to Pedro's family before chucking Mary's head at Pedro's feet. This scene was slightly censored in the Japanese PS2 release, in which you did not get to see Mary's head - even in the normal game, Mary's head is only briefly shown.
