A federal judge has refused to separate trials in the case against five current or former New Orleans police officers charged in a man's fatal shooting after Hurricane Katrina.

Former officer David Warren is charged with shooting 31-year-old Henry Glover before his body turned up in a burned car after the 2005 storm. Two officers are charged with burning the body, while two others are charged with participating in a cover up of the incident.

Warren's lawyers said their client should be tried separately because he didn't burn the body or participate in the alleged cover up, but U.S. District Judge Lance Africk rejected that argument Monday.

Africk said there is a "logical relationship" between the shooting, the body's burning and the alleged cover up.
