NEW ORLEANS - More than 10 years after Hurricane Katrina flooded the New Orleans courthouse's ground floor and destroyed evidence in thousands of criminal cases, evidence is still being stored there -- and a watchdog group says a less-vulnerable storage space is needed.

Court Watch NOLA says city officials should form a working group to find an alternative storage site.

The group says flooding destroyed evidence in thousands of cases in 2005. While court officials say they have a plan in place to move evidence if a storm threatens, the group says a permanent, less vulnerable site is a better alternative.
