• In the months and years that followed, government agencies as well as human rights organisations opened investigations into the massacre at El Aro. However, in 1999 the government investigators that were involved in this work were themselves all murdered. The highest profile human rights defender in Antioquia at that time, Jesus Maria Valle Jaramillo, publicly stated that the Army and paramilitaries had collaborated on the massacre and questioned why Governor Uribe had ignored the plea for help from residents in the period immediately preceding the attack. Uribe responded by accusing Mr Valle Jaramillo of being an "enemy of the armed forces". Then in February 1999, he too was assassinated.

• Some time afterwards Jose Ardila, the CONVIVIR representative who had attended the first meeting at the ranch with the Uribe brothers, had a falling out with Uribe. He was subsequently sentenced to a 60-year prison term but shortly afterwards was taken out of jail. He has never been seen since.

• Since going public with his testimony, Mr Villalba, who himself is in jail, has been the victim of three assassination attempts.
