Instructor: Lou Tessmann, -  Wicklander-Zulawski, is a retired Deputy Chief for the Waukegan (Illinois) Police Department after 23 years of service in a wide variety of experiences including patrol, investigations, training and ultimately Deputy Chief of Police.
Lou is a 26-year veteran of the U.S. Marines, retiring as a CWO-4.  In addition to his service in Vietnam he was activated for Desert Storm and Desert Shield and has received numerous military awards including the Naval Commendation Medal.   Lou began his career as a police officer with the City of Waukegan, Illinois assigned to the patrol division.  He was later assigned to the detective bureau for nine years and as a juvenile officer for one year.  Lou also served as the Commander of the elite Lake County Major Crime Task Force.  The task force works on major criminal investigations relating to homicides, kidnappings, and police-involved shootings.  During his career, he has conducted thousands of interviews and interrogations.  Most noteworthy, Lou has obtained over 80 homicide confessions during his career with only three instances where he was unable to obtain a confession from the homicide suspect.
Lou delivered Wicklander-Zulawski & Associates, inc. (WZ) seminars since 1997 to police and private security organizations throughout the country, as well as internationally in locations such as Tokyo, Japan.  He has been a guest speaker on programs such as the Discovery Channel, Real Detective and America’s Most Wanted.  Lou’s work was recently featured in a Dateline NBC story about convicted child molester Arthur Ream and the unsolved 22-year old murder case of a 13-year old girl in Eastpointe, Michigan.  Lou and Wicklander-Zulawski interviewers assisted local law enforcement with the non-confrontational interrogation of the suspect.  Their joint efforts resulted in a first-degree murder conviction, a mandatory life sentence without the possibility of parole, and the subsequent recovery of the victim's body.
In addition to his TV appearances, Lou was the guest speaker for the 350 members at the Major Case Squad of Greater St. Louis in 2009 and more recently, at the Missouri State Police Annual Homicide Symposium in 2010 and ILEETA Conference in 2011.
Lou graduated from Northeastern Illinois University with a B.A. degree in English and Physical Education and is a member of numerous professional and training organizations including the International Law Enforcement Educators and Trainers Association (ILEETA), International Homicide Investigators Association, and International Narcotics Officers Association.
