NEW ORLEANS (AP) — A federal judge has been asked to postpone the sentencing of a former Louisiana wildlife official who pleaded guilty to taking payoffs from a landfill company owner’s businesses for his work in trying to keep rival landfills closed.

Former Wildlife and Fisheries Commissioner Henry Mouton is scheduled to be sentenced Jan. 25. On Tuesday, prosecutors and Mouton’s attorney asked for the hearing to be delayed six to nine months while he cooperates with investigators. U.S. District Judge Martin Feldman didn’t immediately rule.

An indictment accused Mouton of hiding his financial motives when he lobbied congressional members to keep the Old Gentilly Landfill in eastern New Orleans closed.

The landfill owner whose companies allegedly paid Mouton more than $463,000 hasn’t been named, but the indictment says Mouton touted River Birch Landfill.
