NEW ORLEANS (AP) - A federal judge says allegations of prosecutorial misconduct have tainted a Justice Department inquiry into the source of leaked information about its probe of deadly police shootings on a New Orleans bridge after Hurricane Katrina.
U.S. District Judge Kurt Engelhardt on Monday ordered the Justice Department to conduct a new investigation of news reports that forecast a former police officer's guilty plea while the case was under seal.
Engelhardt initially called for an investigation in June. But he says a report submitted by Jan Mann, U.S. Attorney Jim Letten's former top lieutenant, is tainted and must be redone.
Letten demoted Mann earlier this month for posting anonymous comments on a newspaper website about a Louisiana landfill owner who is being investigated by federal agencies.
