Patio 29, Santiago de Chile

Patio 29 is a common grave site in Santiago General Cemetery in Chile, where political prisoners, especially those who "disappeared" during the 1973 Chilean coup d'état, were buried anonymously. The mass grave, the largest of Augusto Pinochet's military government, was used for unannounced and unmarked burials in the 1970s until an anonymous tip alerted the public to its usage. With the return of democracy to Chile in 1990, an exhumation effort through 2006 recovered 126 bodies in 105 graves and identified three-quarters of the victims. A 2005 DNA test later reported widespread identification errors and a new identification database began in 2007. Exhumation authorities report that the site has been fully exhumed, a claim contested by which families of the victims. ()
