This book is Dave’s first endeavor into writing a full-length book. The book spans from 1970 to the present.  This book deals with his career with the Chicago Police Department and the effects of crime on victims and their loved ones, as well as the impact on detectives and prosecutors. There are numerous true stories including many Homicide Investigations. Even though these cases involved a lot of sadness, a bit of light-hearted moments are intertwined with the stories in the book.  Dave hopes the book contains pleasurable reading but also wishes to carry messages with his writings.


The author spent over thirty-five years as a Chicago Police Officer.  A great bulk of the time spent working in the most violent sections of Chicago both in Patrol Units and as a detective.  The author, as a police detective, investigated thousands of cases relating to Homicide and Gang cases as well as Violent Sexual Assault cases.  Although this is the author’s biography to an extent, it is also a tribute to the many men and women who served in the Chicago Police Department.
