How we do it

Experienced UMPD officers and DPSS security officers assigned to the Criminal Investigation Unit receive additional specialized training. New detectives and investigators attend detective school, interview and interrogation school, crime scene processing and other related training to assist and prepare them for their assignment. Detectives and investigators regularly attend countywide detective and DPSS crime trend meetings. This ensures that our officers stay current, responsive and prepared.
