Laurino in the release. "While Acting Chief Spruill may now be leaving, we are fortunate to have an extremely talented command staff that she leaves behind. I never considered looking outside of our office to find her replacement."

“I selected Acting Capt.

He was hired to help create a Cyber Crimes Unit, and he has shared his expertise in the Adult Trials Section, Narcotics Task Force, Crime Scene/Technical Services Unit, Cyber Crimes/FACTS Unit and Special Prosecutions Unit.
