This method of execution is one of the goriest. The victim's throat is slashed, often with a knife but really any sharp object would do, and then their tongue is pulled out through the open wound. During La Violencia, a Colombian period of history fraught with killing, this was the most common form of execution. It is used mainly to intimidate others who encounter the body after the fact.
The Colombian necktie is sometimes erroneously credited to drug kingpin Pablo Escobar, but this infamous method of assassination was documented as early as 1950. It was later found that Cosa Nostra used it 100 years before, in Italy. It was intended as a method of psychological warfare, meant to scare and intimidate.
