Federal prosecutors are seeking leniency for a former police lieutenant who will be sentenced Wednesday for his role in a plot to cover up deadly police shootings on a New Orleans bridge after Hurricane Katrina.

Michael Lohman faces a maximum of five years in prison when a judge sentences him for pleading guilty last year to conspiring to obstruct justice. Prosecutors have urged the judge to impose a five-year sentence but suspend three years so Lohman is released after serving two.

Lohman is one of five former officers who pleaded guilty to participating in a plot to make it appear police were justified in shooting six people, killing two, on the Danziger Bridge less than a week after the 2005 storm struck New Orleans and plunged it into chaos.
