New Mexico Magazine has this item for May 19th. It took place in 1893.
Clandestine leader Vicente Silva kills his wife north of Las Vegas and hires five henchmen to dispose of her body. Dissatisfied with the paltry $10 payment each, they also rob and kill Silva. Two years pass until the Silva deaths are known. Silva ran a prosperous business by day and at night he was the leader of a feared outlaw gang.
The wages of sin were a little low I guess.
