Taste of Blood 1980

In "Sabor a Sangre" (literally, "Flavor of Blood"), Antonio Aguilar plays Mauricio Rosales, whom along his good friend Chelelo (Eleazar García) are traveling towards another friend's ranch. During their trip, they find the dead bodies of a group of men, so they take them to the next town hoping to find some answers. At the town, they are informed that the dead men were a posse sent by police chief Rómulo (José Gálvez) to kill "El Tigre", a mysterious serial killer who has been hunting down the townspeople, viciously killing even women and children.
