Rosemary Comanse, a 47-year-old Hispanic woman, was found dead in an upstairs bedroom of a Hammond home in the 1100 block of West 177th Place on May 15, 2011. An autopsy determined she died from a single gunshot wound to the back of her head fired at close range.

Rosemary had been separated from her husband, 48-year-old James Comanse, for about a year. James was visiting the home that day; witnesses reported he went upstairs and, roughly five minutes later, a loud boom was heard. It is alleged he then struck another family member in the head with the gun before the weapon was taken from him. Lake County prosecutors charged James with murder and battery in connection with Rosemary’s death.

Rosemary left behind four children and five grandchildren. Does anyone have information about the case, the family, or what happened that day?
