Campo Elías Delgado Morales (Chinácota, Norte de Santander, May 14, 1934 - Bogota, December 4, 1986) was a Colombian assassin, and a veteran of the Vietman war. On December 4, 1986 he became a lightning killer when he murdered 29 people (including his mother) and wounded 15 more in three places in Bogotá: a building to the north where he taught private English, the building where he lived, and the Pozzetto restaurant, which he visited regularly.
