Since then, Riley has made a series of personnel moves and promotions that have increased the role of some of the department's most well-liked officers.
Kotowski, who is the former head of the police officers' union, was promoted by Riley to Sergeant and will now head one of the three crime districts.
Sgt. Kathleen Stanford and Lt. John Rooney have been removed from their high-profile positions as departmental supervisors of the Criminal Investigations Department (CID).
Riley says he made the move after Stanford and Rooney requested to be reassigned.
Sgt. Richard W. Mederos, who formerly worked under Stanford and Rooney, was recently promoted to Sergeant and appointed the new supervisor of the CID.
Riley has focused his efforts since January on reshuffling the HUPD and setting out his crime prevention strategy.
In the months that follow, Riley's plans will be cemented and he can refocus on his primary task--stopping crime.
