Diego Fernando Ramírez

Diego Fernando Ramírez Hernández (place and date of birth unknown) is a former Colombian cattle rancher, murderer and suspected serial killer. The authorities, who've investigated the mysterious disappearances of people in the town of Buga, believe that Ramírez has carried out several killings following the same pattern and modus operandi.

In December 2006, Ramírez proposed a business deal to Gonzalo Díaz Gómez, a renowned rancher from the city of Cali, selling him 60 pigs at the cost of $10,000,000 pesos. Díaz Gómez accepted the deal and offered an advance payment of $5,000,000 pesos, but Ramírez never gave him his property. Due to this, he summoned the rancher to return the money since, according to him, the business wasn't prospering due to a series of inconveniences. On January 5, 2007, they met at a path known as La Palomera, very close to the Cauca River. On that day, Díaz Gómez, who was carrying large sums of money with him, disappeared.

The bodies of both men were later found by authorities on the Ramírez estate, buried in a mass grave more than a meter deep.

Faced with these crimes and other similar disappearances in Buga at the time of the murders, the CTI, a specialized body of the Office of the Attorney General of Colombia, investigated the cases of 6 other persons who were directly related to Ramírez, since they all had had contact with the murderer. Of these, two hotel businessmen (Luis Ángel Rodríguez and Ana Lucía Calderón) were seen talking with him. The conclusion drawn by the authorities is that in most cases, large sums of money were involved.
