Juan Corrales, (November 2, 1954-June 1991) also known as Lizard and Sure Shot was a sicario working for the Medellín cartel.
He, along with Poison, La Quica and Blackie were Escobar's top sicarios. Unlike Quica and Poison, Lizard had a shred of morality within him, and was reluctant to kill Jaime Carrera's wife and child.
Lizard and Poison were killed by a joint DEA-CNP raid in 1991.
