(CNN) -- The Justice Department plans to announce its findings Thursday following an investigation into allegations against the New Orleans Police Department.
Members of the Justice Department's Civil Rights Division will be at a morning news conference about the investigation.
New Orleans Mayor Mitch Landrieu and police Superintendent Ronal Serpas are also expected to be there.
The investigation has already led to several convictions and indictments.
In November, three current and former New Orleans police officers were convicted of shooting and burning a man in the chaos following Hurricane Katrina, then later trying to cover up the crime.
Two other officers -- one current and one former -- were acquitted at the close of the 19-day trial.
Earlier that year, federal prosecutors announced the indictments of at least four New Orleans police officers accused of killing two men in the infamous Danziger Bridge incident.
The shootings occurred at the bridge on September 4, 2005, six days after Katrina slammed into the Gulf Coast.
An indictment alleges that two separate shootings at the bridge resulted in the deaths of a teenager and a 40-year-old disabled man.
Both cases are part of the Justice Department's Civil Rights Division's investigation in what it called "patterns or practices" of alleged misconduct within the New Orleans police department in the aftermath of Hurricane Katrina.
