The suspected Nazi-sympathizing gunman, Julio César Jasso, who planned the Teotihuacán massacre for two months, had a picture in his hotel room showing the scene of the attack depicted in his room. The gunman, who killed a Canadian tourist and injured 13 others, had asked about staying in a hotel room between April 8 and 20, and had to pay 50% of the total to reserve the vacancy. He booked the room under the name “Julio Cesar Ramirez” and sent proof of his bank transfer. The hotel room had a 4x4 room with a picture depicting the scene from the Pyramid of the Moon. The Mexican President has ordered Mexico's security cabinet to investigate the incident.
