WBRZ - Baton Rouge

A former New Orleans police detective has been charged with helping conceal a conspiracy by police to cover up a deadly police shooting of unarmed civilians after Hurricane Katrina.

Jeffrey Lehrmann is the second former member of the police department to be charged in a federal probe of shootings on the Danziger Bridge that killed two people and wounded four others.

Police are accused of fabricating witness statements, falsifying reports and planting a gun in an attempt to make it appear the shootings were justified.

Michael Lohman, a retired lieutentant, earlier pleaded guilty to conspiring to obstruct justice.
