The principal operational Vidocq Committees which specifically assist Law Enforcement entities are the Training Committee, The Case Management Committee and the Case Assistance Committee.  All of these Committees are headed by experienced former Law Enforcement members.


The Training Committee is headed by Ed Gaughan, a former senior Detective in the Philadelphia Police Department, provides pro bono assistance in the form of cold case homicide seminars by forensic and investigative experts to law enforcement agencies, regional cold case associations and prosecutors’ offices.  During these seminars, investigators can also request the experts to review their entire case file, including evidence available for forensic laboratory analysis. The Vidocq Society will provide advice or recommendations for further investigation in order to attempt closure for these cases. Presentations and counsel have been provided to groups in many regions of the United States.

Case Management

The Case Management Committee, which is headed by Bill Gill and Carol Sweeney, is the principal point of contact for law enforcement agencies seeking the Society’s assistance.  It arranges for law enforcement personnel to present their cases at the Society’s meetings in Philadelphia, and coordinates post-presentation follow up.

Case Assistance

The Case Assistance Committee works directly with law enforcement and prosecutorial agencies. It is headed jointly by Ben Redmond, retired Regional Director U.S. Treasury Department, IRS Inspection Service, Mid-Atlantic Region; and Jack Maxwell, retired Chief of Detectives, Philadelphia Police Department.

All requests from law enforcement agency representatives for “on site” specialized investigative assistance in their jurisdictions must be made through this Committee.  Approval for this assistance must be made jointly by Vidocq Counsel and the respective Prosecutor in that jurisdiction.
