After the assassination of Luis Carlos Galán, the administration of César Gaviria moved against Escobar and the drug cartels. Eventually, the government negotiated with Escobar and convinced him to surrender and cease all criminal activity in exchange for a reduced sentence and preferential treatment during his captivity. Declaring an end to a series of previous violent acts meant to pressure authorities and public opinion, Escobar surrendered to Colombian authorities in 1991. Before he gave himself up, the extradition of Colombian citizens to the United States had been prohibited by the newly approved Colombian Constitution of 1991. This act was controversial, as it was suspected that Escobar and other drug lords had influenced members of the Constituent Assembly in passing the law. Escobar was confined in what became his own luxurious private prison, La Catedral, which featured a football pitch, a giant dollhouse, a bar, a Jacuzzi, and a waterfall. Accounts of Escobar's continued criminal activities while in prison began to surface in the media, which prompted the government to attempt to move him to a more conventional jail on 22 July 1992. Escobar's influence allowed him to discover the plan in advance and make a successful escape, spending the remainder of his life evading the police.
