General Mario Montoya was commander of the area police force during the operation. The report cites an informant who claimed that plans for the attack were signed by General Montoya and paramilitary leader Fabio Jaramillo, who was a subordinate of Diego Fernando Murillo Bejarano, also known as Don Berna. Don Berna became known for taking over the drug trade around Medellín after drug kingpin Pablo Escobar was killed.[1]
