A Huntley man who shot and killed his brother last month in a fight over living arrangements, turned the gun on himself afterward, authorities said Thursday.
Mark Grundei, 50, died Wednesday of severe head injuries at Hospice Care Center in Woodstock, Huntley Police Deputy Chief Mike Klunk said.
An autopsy Thursday revealed Grundei died from a single, penetrating gunshot wound to the head. The preliminary determination is that it was a suicide, according to the McHenry County coroner's office.
Robert Grundei, 48, died following the May 26 fight after being shot in the back by Mark Grundei at the family's Sun City home on the 11000 block of Morning Glory Lane, Klunk said.
Mark Grundei was in critical condition in the intensive care unit at Advocate Sherman Hospital in Elgin before being moved to hospice care, Klunk said.
The brothers' mother, Alyce Grundei, suffered a head wound from a grazing bullet while trying to break up the fight, Klunk said. She had been treated and released from the hospital.
Police said the brothers were fighting over who was going to live in their mother's Sun City house, even though the property had been sold to a new owner.
Mark and his mother were living in the house when Robert, formerly of Coral Springs, Florida, decided to move into the house.
Robert had been staying at the house to help with its sale and with funeral arrangements after the death of the youngest brother, Brian, 45, who drowned in Lake County earlier in May, police said.
Alyce called police to the home shortly after 5 p.m. May 26, authorities said. She met officers at the door and was bleeding from the head and had an eye injury. She told police her sons were inside the home and had been shot.
