Solid Knowledge of Criminal Justice

The art of investigation lies in gathering and evaluating information and evidence by which any alleged matter of fact is proved or disproved. The skilled investigator must be able to elicit useful information that is admissible in court. He must know how and when to ask the "right" questions.

My more than 30 years in law enforcement in Illinois and Wisconsin has taught me how to question victims, witnesses, complainants and suspects, and to utilize a variety of sources to obtain essential information. I have developed the skills and techniques to recognize, collect, evaluate, process, and preserve evidence.

After data has been collected, collated, and analyzed, it must be reported. Common sense and sound judgment enhanced by my past experiences have prepared me to assist you in your investigative needs. A career that resulted in over 15,000 felony arrests and the responsibility for more than 1,000 homicide investigations assures you of professional reports and expert courtroom testimony.
