"Riverdale" creator pleads for release of father, who is a political prisoner in Nicaragua: "We have no idea how this ends"

Roberto Aguirre-Sacasa, executive producer and series creator of the hit show "Riverdale," is pleading for the release of his father, Francisco, a 77-year-old political pundit and former Nicaraguan foreign minister. He has been sitting for more than 60 days in Nicaragua's notorious "Nuevo Chipote" prison, where critics of President Daniel Ortega's government are being subject to mistreatment and torture, activists and family members say. 

"The biggest fear is that I'm not gonna get a chance to see him again, and that one day, we're going to get a call that says he died in jail," Roberto told CBS News in an interview. 

Francisco is one of 37 people that include presidential candidates, journalists, students and others that have been detained in Nicaragua since late May, according to Human Rights Watch.
