HUNTLEY – The man who died following a domestic shooting in Huntley fell victim to a gunshot wound in the back, the Kane County Coroner’s office said Wednesday.
Meanwhile, his brother – believed to be the shooter – remained in critical condition Thursday, still yet to interview with police about the Memorial Day incident.
The coroner’s determination – which differed from police’s original report that Robert Grundei, 48, died of shoulder and head wounds – doesn’t change the working theory of Monday evening’s events, Huntley Deputy Chief Michael Klunk said.
Mark Grundei, 50, Robert’s brother, still is believed to be the man who pulled the trigger at least five times, killing his brother and injuring their mother before turning the gun on himself.
Police have documents indicating that the gun – a .38 special revolver – belonged to Mark Grundei, Klunk said.
Charges are yet to be filed in the matter, although Huntley authorities have been in contact with the McHenry County State’s Attorney’s Office, Klunk said.
“It’s still under investigation,” Klunk said Thursday. “We want to put all of our theories together and make sure we have a good solid plan.”
Mark Grundei remained in critical condition at Advocate Sherman Hospital in Elgin on Thursday, according to hospital spokeswoman Tonya Lucchetti-Hudson.
Klunk said Mark Grundei was still in the intensive care unit as of Wednesday. Authorities have been short on definitive statements thus far, in part because they haven’t been able to talk with him.
Mark and Robert’s mother, Alyce Grundei, 81, was released from Sherman Hospital on Monday night after she was grazed in the head with a bullet during the incident.
Police have said they believe Alyce Grundei was trying to break up the two men, who were arguing over living arrangements.
Robert Grundei was up from his permanent address in Coral Springs, Florida, to mourn a third brother, Brian, who drowned weeks earlier in Lake County. Mark Grundei had been living with their mother, but police have said the two were arguing about Robert’s plans to live with Alyce, forcing Mark out.
