In
Ernesto Samper's government he was appointed director of the police anti-kidnapping squad GAULA. In 1996 González once again allied with drug trafficker
Victor Patiño-Fomeque to secure the release of Juan Carlos Gaviria, brother of former Colombian President César Gaviria. Gonzalez is believed to have orchestrated the kidnapping to further destabilise the Samper government, which was affected by
Proceso 8000. González at the same time got credit for apparently commanding the police squad that killed drug lord
José Santacruz Londoño, in an alleged alliance with paramilitary chief
Carlos Castaño Gil, which turned out to be a set-up as Castaño would kill Santacruz at the instigation of the Norte del Valle Cartel. His forced resignation, imposed by the government, was apparently due to his closeness to the underworld, although according to
Andrés López in his book
El Cartel de los sapos, this relationship had been well known since his involvement with the police. González later worked with drug traffickers
Luis Hernando Gómez Rasguño and
Wilber Varela Jabón in security and as a liaison with the police, who were corrupted by drug traffickers.
Rasguño accuses him of having assassinated conservative leader
Álvaro Gómez Hurtado. At the same time, in
Jorge 40's book, he mentions that in May 1997
Salvatore Mancuso and eight other men were imprisoned one night and interrogated by a prosecutor, who, through the efforts of paramilitary leader González, arrived with an order from the police commander to let them go. == Assassination ==
