Welcome to WAHI!


The Wisconsin Association of Homicide Investigators was founded in 1996 in response to requests for specialized training in the area of death investigation. The object of forming the association was to further the education of it's members, and all law enforcement. Since that time the Annual Training Conference of the Wisconsin Association of Homicide Investigators has drawn attendees from across the United States.
