WBRZ - Baton Rouge

Prosecutors are asking a federal judge to reconsider his refusal to postpone a sentencing hearing for Jeffrey Lehrmann.

Lehrmann is a former New Orleans police detective who pleaded guilty to helping cover up a deadly police shooting after Hurricane Katrina.

Justice Department lawyers want the judge to postpone Lehrmann's sentencing until after a trial for other current or former officers charged in the same case.

The Justice Department says it can't fully evaluate Lehrmann's cooperation or recommend a more lenient punishment if he is sentenced next month.
