FEMA officials have agreed to check whether sex offenders who evacuated after Hurricane Katrina have registered for federal aid.
The Federal Emergency Management Agency says it would then notify communities across the country that might have sexual offenders living within them.
A Texas prosecutor, Bexar County District Attorney Susan Reed, received the assurance from Vice Admiral Thad Allen, the Coast Guard commander in charge of FEMA's response to Hurricane Katrina.
FEMA has been criticized for allegedly blocking law enforcement efforts in identifying sex offenders and parolees who have fled hurricane ravaged areas.
A spokesman with FEMA in Washington says those reports are incorrect.
New Orleans had more than 1,300 registered sex offenders. The parishes around New Orleans had another 400, and at least 3,500 were registered in Mississippi.
