Clara Aravena, sister of Juan Aravena, an inmate who died during a fire at San Miguel prison, holds up pictures of her brother in front of the Legal Health Service centre in Santiago on December 9, 2010. A fire killed at least 83 inmates in the prison early Wednesday in what officials said was the worst ever disaster on record in Chile's overcrowded and &quot;inhumane&quot; prison system.
