It was over 150 years ago that the two brothers came to live in the city of Guanajuato. They came from Europe , so it was said, and their surname was Karlkaman.

The Karlkaman brothers would soon be known as "the Carcamans," or in Spanish, "Los Carcamanes," as people mispronounced the name. Their life went on peacefully and pleasantly, that is, until one terrible day.

At dawn on the morning of June 2, 1803 , the news spread around the town in an instant that neighbors had found the "Carcamanes" brothers dead in their home.

The story goes that when the neighbors entered the house through the door left open, they saw a tragic, bone-chilling scene. A double homicide. The motive: burglary.

At least that was the first hypothesis as to the entirely unexpected deaths. The truth, however, was another story altogether.

A young woman who lived nearby, promiscuous as she was beautiful, was also found murdered, a terrible stab wound in her heart, that same June morning. That less-than-chaste young maiden was the lover of both brothers. The first, possessed by rage, waited one evening for the second to arrive home. And as it happens in these cases, neither kinship nor a life spent together in friendship could prevent the terrible tragedy about to occur.

In an explosion of violence, the "Carcamanes" brothers locked in a fight to the death, where Nicolás lost. Arturo, though badly hurt, dragged himself along the wall with bloodied hands, and made his way to the house of his unfaithful lover, to murder her in her bed. When he returned home, he took his own life with the same dagger.

After the investigations and routine procedures of the corresponding authorities, the body of Nicolás was buried at the Church of San Francisco , and Arturo at the Cemetery of San Sebastián.

According to legend, between the Church of San José and the house where the brothers lived, three specters haunt the night, bewailing their deaths and their punishment.
