With a little help from Delta Force, according to Mark Bowden in Killing Pablo.
It was that eavesdropping gear....some Army intel group with King Airs.
PEPES brought down all of Pablo's cover and forced him to act foolish in constantly calling his son and with less and less help from his folks.
Delta did not kill Pablo. Colonel Martinez's soldados did....they wounded and then executed him and rigfhtly so.
American Spec Ops guys alongside the Colombian Elite Battalions (bush hats and tiger striped outfit and fairly uncorruptable) are who killed Gonzalo Gacha SW of Cartagena after 2-meter intercepts and tailing his 15 year old son....who they also killed.
I was in Colombia on a Brasilian passport and was stopped and interrogated by US military along with the aforementioend Elites back in 1989 on the Hwy between Baranquilla and La Cienega.....
there has been "quiet cooperation" a long time
lol.....18F mighta been there...lol
