The gunman who opened fire atop Mexico's ancient Pyramid of the Moon appeared to have been influenced by other violent shootings and showed signs of psychological problems, the country's president said on Tuesday. Julio César Jasso Ramírez, 27, carried a handgun, dozens of cartridges, a knife, and literature referencing acts of violence. He planned and executed the attack alone and fatally shot himself after a standoff with police.

A Canadian woman lost her life and 13 others were injured at the popular tourist site near Mexico City.
