Patricio Rogelio Santos Fontanet

Personal life and aftermath Fontanet and his partner Estefanía Miguel had a son named Homero, born in October 2012. Fontanet's father José Santos died while he was in prison in November 2017, with a court granting him a brief supervised release to attend the funeral and accompany his mother.

In November 2010, Fontanet and other Callejeros members founded the Argentine rock band Don Osvaldo. After his definitive release in May 2018, Fontanet became active again, though sporadically, in Argentine music. He appeared in 2021 and 2022 in neighborhood clubs and in a concert near the Obelisco de Buenos Aires. Fontanet's performances have received generally positive reactions, with the exception of civic associations related to some families of Cromañón victims who have filed petitions to declare Fontanet persona non grata in several localities in Argentina.
