Three weeks ago, I reported the details of the massacre in the Guru bar in Envigado, a suburb to the south of Medellin. Two gunmen had stood before the crowded venue and opened fire, killing eight patrons and leaving 13 wounded (original reports spoke of 26 injured). According to survivors, both assassins had a gun in each hand, firing them simultaneously as if in a Hollywood film. Police later confirmed that the perpetrators had used high caliber “police killer” ammunition, which can traverse bulletproof jackets. The latest news is that the killers themselves were murdered in the gritty La Sebastiana neighborhood of Envigado, only two days after the Guru shooting.
