One man was shot to death and his mother and brother were wounded when an argument erupted as the family gathered for a funeral in far northwest suburban Huntley, police said.



The shooting happened around 5 p.m Monday in the 11400 block of Morning Glory Lane as the family was mourning the death of a third brother, Brian Grundei, who drowned in a Deerfield retention pond on May 16, Deputy Police Chief Mike Klunk said.



Robert Grundei, 48, had come to town from Coral Springs, Fla., for his brother's funeral, according to Klunk. Grundei and his older brother got into a dispute sometime Monday afternoon, though it was not clear what the argument was about, Klunk said.



The men's mother, age 81, called 911 at 5:09 p.m. to report that she had been shot. When officers arrived at the home, she was holding a gun and told police her sons were shot inside, Klunk said. Officers took the gun and found Grundei and his 50-year-old brother in the home.



Grundei was shot in the head and shoulder, and died from his wounds. His older brother suffered a "contact wound" to the head, and their mother was bleeding from a graze wound to the head and had an eye injury, police said.



Klunk said it appeared the older brother's wound was self-inflicted but police had not definitively determined whether he shot his brother and mother.



The older brother was being treated at Advocate Sherman Hospital in Elgin for "severe" gunshot wounds Monday night, while the men's mother was expected to be treated and released from the same hospital, police said.



"We haven't talked to him yet," Klunk said. "We're doing gunshot residue tests on them as part of our investigation."



Klunk said that his department's only prior contact with the family was to notify them of Brian Grundei's death earlier this month.
