Intro
I’m a retired police lieutenant and licensed Illinois private detective with more than 35 years of combined law-enforcement and private-sector experience. I provide confidential, defense-oriented investigations for criminal defense attorneys, legal professionals, businesses, and private clients. My job is to find the facts, wherever they fall, and to report them clearly enough to stand up in court.
