Even as journalists and judicial investigators spent years trying to crack the La Penca mystery, Torbiörnsson kept silent about his knowledge of the bomber's Sandinista connection. However, tormented by the idea that he had been used as an unwitting accomplice to a terrorist attack and disillusioned with the Sandinistas, Torbiörnsson finally broke his silence. He traveled to Managua in January 2009 and submitted a declaration to Nicaraguan police in which he pointed to Montero, to former Sandinista Minister of Interior Comandante Tomás Borge, and to former chief of Nicaraguan state security Lenín Cerna as the masterminds of the bombing.
