In October 2003, Berenson married Aníbal Apari Sánchez, 40, whom she had met in 1997 when they were both incarcerated at Yanamayo prison. Apari Sánchez was convicted of being a member of the MRTA. When he was released in 2003 on conditional liberty (parole) in Lima, his travel was restricted, and he was accordingly not present at the wedding in Cajamarca and had to be represented by his father. Later he was allowed conjugal visits. Apari Sánchez is now a practicing attorney in Lima and directs a non-governmental organization (NGO) that assists individuals formerly imprisoned on charges of assisting or being members of the MRTA in their rehabilitation into society. He is also co-founder of a political party, Patria Libre, that participated in the 2011 national elections.
