A Minnesota couple's prank idea for a viral YouTube video went terribly wrong. Monalisa Perez, 20, and Pedro Ruiz, 22, were hoping to boost their YouTube following by having Perez fire a 50 caliber handgun at Ruiz while he used a book in an attempt to stop the bullet. Ruiz was later pronounced dead. The couple even said they tested the stunt already. Perez was charged with reckless discharge of a firearm. The couple already had one child together and Perez is currently seven months pregnant with their second.
