The McHenry County Coroner's Office exists to provide the people of McHenry County with a thorough investigation in the event of a death. This investigation may include, but is not limited to, autopsy, toxicology tests, metabolic studies, x-rays, entomological studies, and personal as well as psychiatric history. These procedures are done to insure that the facts surrounding the death are brought forward, and if an Inquest is held, the jury will have as many facts as possible to arrive at a manner of death.

It is the goal of the McHenry County Coroner's Office to not only thoroughly investigate deaths that occur in McHenry County, but also to prevent as many deaths as possible. This is accomplished through education. Several presentations are given each year at local high school health classes and pre-prom programs to alert the students to the dangers of drug and alcohol abuse. We also give programs to various service groups and the general public to inform them of the duties and workings of our office. The Coroner's Office also co-sponsors training programs for paramedics, police officers and other emergency workers to enhance current job knowledge and skills.
