Mario and Fernando Almada are brothers that ended up in the same movie, with Mario as Sheriff Bob (BOB!) and Fernando as the equally epically titled Roy. They had another brother named Horacio who stayed home, far away from this movie that’s pretty much a cop movie that turns into a Mexican giallo. No puedo creerlo!

Speaking of family, this was directed by the father and grandson team of Pedro Galindo and Pedro Galindo III. The elder Pedro was an actor, producer and musician. His song “Malaguena Salerosa” is on the soundtracks for Kill Bill and Once Upon a Time In Mexico. Meanwhile, Pedro III made the crowd pleasing Vacaciones del Terror 2 and Trampa Infernal.

Anyways, there’s a killer loose cane with a sword in it and a giant dog that helps him murder, paying back that mutt who used to talk to Berkowitz.

This has one of the best kills I’ve ever seen in an exploitation movie, where a dead man is thrown through a glass window and on to the stage of a strip club, where his lifeless form collides with a fully nude dancer.

A movie that skirts the edge between slasher and giallo, which is a thin one when you think about it hard enough. This is dark and scummy, which is pretty much exactly what you’d hope it would be.

There’s also a sequel, Massacre In Rio Grande, that I’ve been trying to hunt down. If you can find it, let me know. I’ll be your mejor amigo!
