Guillermo Alejandro Pallomari González (born October 1, 1949),[1] nicknamed Reagan,[2][3] is a Chilean accountant who worked for the Cali Cartel and participated in a scandal involving financial fraud during the 1994 Colombian presidential election that bestowed Ernesto Samper (now former president) as winner of the respective elections.

In 1973, during the military dictatorship of Chile (1973–1990), Pallomari moved with scarce economic resources, to Colombia.

He married Gladys Patricia Cárdona, and along with her, founded a technological company called Universal Link.

[4] In 1990, he began working for the Rodriguez-Orejuela brothers, as chief accountant to manage their illicit drug trade.

After collaborating with information concerning Ernesto Samper's electoral fraud[5] (in which he received more than USD $6 million to finance his campaign expenses; equivalent to $10.5 million in 2020)[6] and Cali's illicit operations, he moved to the United States to testify and is under the Witness Protection Program.
