Jeffrey Lehrmann, a government witness in the federal trial of five current or former officers, said he saw Sgt. Arthur "Archie" Kaufman retrieve a gun from his home several weeks after the deadly shootings on the Danziger Bridge. Kaufman later turned the gun in as evidence, claiming he found it under the bridge a day after the 2005 shootings that left two people dead and four others wounded.
Lehrmann said Kaufman instructed him to fill out paperwork that claimed the gun belonged to Lance Madison, whose mentally disabled brother, Ronald, was shot and killed on the bridge. Lance Madison was arrested on attempted murder charges and held for more than three weeks before a judge freed him.
Lehrmann said Kaufman, his supervisor, had grown concerned because the judge who freed Madison didn't believe Kaufman's testimony at the hearing.
"Therefore, we needed a gun," Lehrmann said.
Lehrmann said Sgts. Robert Gisevius and Kenneth Bowen joined him and Kaufman when they drove to Kaufman's house to retrieve a gun. Kaufman emerged from his garage carrying the gun in a brown paper bag, calling it a "ham sandwich," Lehrmann said.
Kaufman's attorney, Stephen London, suggested during cross-examination that Lehrmann was trying to shift blame to his client and has changed his story over time. Lehrmann accused London of "nitpicking," while London chided Lehrmann for smiling during his testimony.
"My client is on trial. Is that funny?" London asked.
"No, it's not funny at all," he responded.
On Sept. 4, 2005, Lehrmann drove himself to the Danziger Bridge after a truckload of officers responded to another officer's distress call and began shooting. He isn't accused of firing his gun that day.
Lehrmann said he handcuffed Ronald Madison on the west side of the bridge after he was shot, then felt badly about it when another officer told him he already was dead.
Lehrmann said the officers immediately afterward started to "get their stories straight."
"We had a lot of problems because it was a bad shoot," he said.
"What was the goal of the cover-up?" prosecutor Cindy Chung asked.
"Protect the officers from legal ramifications," he said.
Lehrmann said he helped Kaufman with an initial, 32-page report that was bounced back by Lt. Michael Lohman, who also has pleaded guilty to participating in a cover-up.
"Lt. Lohman became irate with Archie because he thought Archie's report was garbage," Lehrmann recalled.
Lehrmann said the false accounts of what officers did on the bridge continually changed as they honed their cover story.
"The lies changed whenever we needed to change them," he said.
Lehrmann said he made up the name "Lakeisha" for a phony witness to the shootings when Kaufman called out, "Hey, somebody give me a name!" He said they also fabricated a witness named "James Youngman" and reported he lived at a large, storm-damaged apartment complex where it would be hard to prove the witness didn't exist.
Weeks after the shooting, Lehrmann said he and Bowen returned to the bridge a day before crime scene technicians were to collect evidence. Lehrmann said he saw Bowen kick shell casings off the bridge where police shot several people.
Gisevius, Bowen, Officer Anthony Villavaso and former officer Robert Faulcon are on trial for charges stemming from the shootings. Kaufman is charged in the alleged cover-up.
Lehrmann, who already has been sentenced to three years in prison, is one of five former officers who pleaded guilty to participating in a cover-up. He is the fourth of those officers to testify at the trial, now entering its third week.
