El Silbón

El Silbón or The Whistler as he called when his name is translated is a violent Spirit from Venezuelan & Colombian legends. In most tellings of his story, he is stated to have been a simple farmer before becoming the infamous spirit he is now, after having killed his father.

Venezuelan version
Once upon a time, a young man was working in his father's farm in Venezuela, received a notice about his wife who has been called a whore by her own father (or his father) and killed by him which put him in great rage over him and killed his father-in-law (or father), the farmer's grandfather decided to exact punishment on his grandson by commanding some other farmers to brutally torture his grandson in a long painful revenge, first whipping his grandson's back and put salt to increase the pain and finally, to kill his grandson his put in a loose two monstrous black dogs who bite his ankles, while he scream and pain and fled to the jungle nearby, where his body is never to be found.

Some people said that afterward, his spirit becomes a damned soul, hell-bent into killing mostly drunks or adulterers he found in his way, as well as attacking and scaring any person who heassr his terrifying whistle.

Colombian version
The Colombian version has the same sort of backstory as the Venezuelan one, except it has drunkards being the main victims of El Silbón (mainly as a way of deterring one from the craving of alcohol). El Silbón stalks the Llano region in Colombia on rainy nights during May and June, and is often encountered by drunkards going home from the bars. The Whistler is more sympathetic than his other counterparts, as he is more of a harbinger of death than the actual cause, and he likes to attack wrongdoers (drunkards) rather than maliciously attack humanity.

Alternate version
In this alternative version, El Silbón was merely a spoiled young farmboy who demanded his father make him some venison for dinner. Upon finding out his father had never cooked any meat, El Silbón got infuriated, and killed his father brutally before ripping out his father's entrails, and then cooking them up. He gruesomely took his father's cooked entrails to his mother, and they ate them. But his mother found out the entrails were from her own husband, she got sick and infuriated, and cursed her son to forever have misfortune, which he so rightly deserved after this heinous and disturbing act. He fled into the wilderness and has returned as a malevolent spirit, presumably after dying of exposure.
