The longest sentence for any member of the American military linked to a torture-related death of a detainee in Iraq or Afghanistan has been five months, a human rights group reported Wednesday. In only 12 of 34 cases has anyone been punished for the confirmed or suspected killings, said the group, Human Rights First, which is based in New York and Washington. Beyond those cases, in almost half of 98 known detainee deaths since 2002, the cause was never announced or was reported as undetermined. In dozens of cases documented here, grossly inadequate reporting, investigation and follow-through have left no one at all responsible for homicides and other unexplained deaths," it said in the report, based on military court records, news reports and other sources. The Pentagon says it conscientiously investigates such deaths. When asked Wednesday for a status report on investigations and prosecutions in individual cases of abuse, the Pentagon said it could not offer a comprehensive compilation because the information was too scattered. Army lawyers at the Pentagon do not "have access to the information because other Army commands have the documents," Maj. Wayne Marotto, a spokesman, said.
