Professional Accomplishments



Private Investigator / Sheriff’s Detective Lt.

1976 – 201979: I was a patrolman for Chikaming Twp & New Buffalo City Police Department.

1970 – 2004: I was a Berrien County Sheriff’s Department deputy then Detective Lt.

2015 – 2020:  I’ve been a private investigator working under Lange I.C.S.S


January, 2020: Received my Michigan Private Investigation License. (#3701207823) and launched Michigan Private Investigations and Process Service.


Between my private investigations and criminal investigations as a Berrien County Sheriff’s Detective I’ve worked hundreds of cases including homicides, robberies, burglaries, child abuse cases and much more.  My criminal conviction rate was more than 99%.


I was considered (by my peers and supervisors) to be an expert in interrogations and interviews.  More than 70% of the cases I handled resulted in confessions from the defendant.

Twenty-Eight-Year Police Veteran

As a brand-new patrolman, not quite twenty years old, I identified that proper forensic photography was not being done at any level of investigations.  I used my own equipment and taught myself forensic photography, which expanded my photographic and computer skills that led to opening my own portrait studio.

I accomplished my goal to become Detective Sergeant ever at the Sheriff’s Department by gaining the promotion at age 28.  In addition to investigating crimes, I worked with another person in the records division to develop a first-of-its-kind system in our jurisdiction that used the mainframe computer to identify and compare stolen property with property sold at pawn shops, and shared that information with neighboring agencies to make crime solving more efficient.

I was promoted to lieutenant and made commander of the Berrien County Narcotics Unit at age 39, supervising 11 detectives and 1 administrative assistant, and was also responsible for computer implementation, development, and support to make investigations and coordination with other agencies more productive.   During this time, I was also working as second in command of a tri-county drug enforcement unit involving local, county, state, and federal investigators and cases.

By 1998, I’d earned a new title: “Technology Coordinator”.  This position was established because the Sheriff’s Department was in the middle of a challenging refit of computer software for the overall management of the criminal justice system.  I worked with the County Information Systems Department to get the project on track and make the computer system more user friendly as well as provide training and support to the end-users. In addition to installing hardware and software, I wrote the system documentation and kept it current with ever changing software, which eventually stabilized and is still in use today.

My responsibilities included creating and implementing the first web site for the Sheriff’s Department.  It was recognized as one of the first in the state and complemented by many other departments that followed our lead.

Two years after this project started, I was also put in charge of the Sheriff’s Department Records Bureau and the 911 Center.  This assignment required evaluating the constant evolution of new software to make the officers’ jobs easier and the public safer.
