Three days after being officially named the city’s top cop, New Orleans Police Superintendent Michael Harrison on Friday announced several appointments to the upper ranks of the Police Department.

The positions are largely out of the public eye and focus on areas including recruitment and implementing the consent decree.

Rannie Mushatt, a 31-year veteran of the department, will become deputy chief in charge of the Investigations and Support Bureau. He is now commander of the Criminal Investigations Division.

In his new position, he will oversee several offices, including the Criminal Investigations Division, which investigates homicides and sex crime; the Specialized Investigations Division, which has gang investigations among its duties; and the Crime Lab and Evidence Division.

Richard Williams will take the helm of the Education, Training and Recruitment Division, which entails managing the Police Academy. Williams, who has been with the NOPD for 23 years, is now a lieutenant in the Public Integrity Bureau, which investigates complaints against officers.

His new assignment returns him to a position he held from 2007 to 2011.

John Thomas, who is in charge of the Crime Lab and Evidence Division, will become the commander of the Compliance Division.

In that role, the 23-year veteran — a former commander of the 3rd District, which covers Gentilly — will be tasked with making sure that departmental policies, such as use of body cameras and performance standards, that are part of the consent decree are implemented and met.

Doug Eckert, a district investigative unit commander in the 2nd District, which patrols the Uptown area, will take charge of the Crime Lab and Evidence Division. Eckert has been with the department for 17 years.

“As superintendent, my top priority is to improve the relationship between our officers and our community and to make our streets safer,” Harrison said in a written statement. “After assessing the needs of the department, I am confident that the new leadership in place can work together to effectively take on the challenges ahead.”

The changes take effect Sunday and mark the second time Harrison has made changes to the department’s leadership since he replaced former Superintendent Ronal Serpas on an interim basis two months ago.

Days after being named interim superintendent, Harrison named former 6th District Cmdr. Bob Bardy as deputy superintendent in charge of the Field Operations Bureau, the department’s No. 2 position.

Bardy, a 40-year NOPD veteran, replaced Daryl Albert, who was shifted to deputy superintendent of the Investigation and Support Bureau.

Lt. Ronnie Stevens was named Bardy’s replacement as commander of the 6th District, which includes Central City, the Garden District and Irish Channel, while Lt. Lawrence Dupree replaced Harrison as commander of the 7th District, which is made up of New Orleans East.
