Iraqi Convicted in Aid Worker Killing May Have Escaped VOA News 15 July 2010 October 2004 File photo of some 200 demonstrators, many of them handicapped, protesting the kidnapping of Iraqi CARE director Margaret Hassan in Baghdad Photo: AP October 2004 File photo of some 200 demonstrators, many of them handicapped, protesting the kidnapping of Iraqi CARE director Margaret Hassan in Baghdad An Iraqi man convicted in the 2004 kidnapping and killing of a British aid worker may have escaped from prison. A lawyer for former Care International worker Margaret Hassan told the French news agency that Ali Lutfi Jassar al-Rawi did not appear at a Thursday appeal hearing. Hassan's lawyer says Iraqi officials have told him Jassar is missing from prison and his whereabouts are unknown. Last year, a Baghdad court sentenced Jassar to life in prison for his role in Hassan's death.  Iraqi officials had sentenced a second man, Mustafa Salman al-Jibouri, to life in the case but later reduced his sentence on appeal. Hassan had lived in Iraq for 30 years and served as the head of Care International in Baghdad.  After she was kidnapped, she appeared in several videos appealing for British forces to withdraw from Iraq. Investigators have not found her body.   Some information for this report was provided by AFP. .
