Juan is serving a sentence of 23 years, having been arrested on September 18, 2014 and charged with incendiary attacks on police stations in 2014 claimed by the Conspiracy Cells of Fire and International Conspiracy of Revenge. On July 23, 2014 a CCF cell bombed "The Dominicans" station of the Santiago Metro, and on September 8, 2014 a shopping mall in Las Condes. In both instances, measures were taken to ensure the bombs would not hurt anyone, but in the former a bag containing the bomb was moved by a Metro employee, and in the latter the police ignored a warning call the CCF cell made before the bomb was set to go off. As a result, people were injured, and the Chilean state claimed they were meant to terrorize the population. They used an anti-terrorism law to obtain maximum sentencing on March 15, 2018 after Juan was found guilty: 15 years under the antiterrorist law for the attack on the sub-center and 8 years for the arms control law and less serious injuries for the attack on the Los Dominicos subway. Two others were initially charged alongside Juan, but, after over 3 years of detainment and criminal proceedings, were found not guilty on all counts.
