In December 1996, the MRTA seized the Japanese Ambassador's residence in Lima and demanded that MRTA prisoners be released in exchange for the release of their hostages. MRTA leader Nestor Cerpa, Nancy Gilvonio's husband, led the takeover of the Embassy. Berenson was third on a list of MRTA prisoners whose release was sought by the hostage-takers. After 126 days, the standoff ended in a raid by Peruvian special forces in which all hostage-takers were killed. Two military personnel, commander EP Juan Valer Sandoval and captain EP Raúl Jiménez Chávez, and one of the seventy-two hostages, Carlos Giusti, were also killed.
