Inter-Facts Investigations dates back to 1960. The nucleus of our company was born out of Factual Services Bureau, one of the nations 1st Investigation companies serving the Insurance industry. We are experts at gathering information using old-school Private Detective know-how, as well as the latest investigative technology.


Inter-Facts principle William (Bill) Lamb, a licensed Private Detective, began his professional investigation career in the 1980’s in the Military Police, moving into Military Police Investigations within one year. Following service to his country, Mr. Lamb moved into a management position, while always having the thought of returning to investigation work. In 1995, he accepted a position working for Insurance Investigative Consultants, one of the nation's original investigation firms, providing support to the insurance industry. William Lamb continues to review every file before it reaches a client's hands.
He also personally handles criminal defense investigations for some of Illinois top law firms.
