In Haiti, a former leader of the country’s death squads, Louis-Jodel Chamblain, surrendered to justice officials yesterday. Chamblain was sentenced in absentia to life in prison in 2000 for killing supporters of President Jean Bertrand Aristide. He was also a leader of the paramilitary group FRAPH, the Front for the Advancement of Progress of the Haitian People, that is believed to have killed 3,000 civilians during the 1990s. Chamblain fled to the Dominican Republican in 1994 but returned in February to help lead the U.S.-backed ouster of Aristide, Haiti’s first democratically elected president.
