Several Huntley police cars at the scene at 11469 Morning Glory Lane in Monday Huntley. Three people were injured after a shooting occurred, according to the Huntley police chief John Perkins. Huntley police responded to a call around 5:30 p.m. At least two people were shot with a handgun, one in the head, one in the chest.

HUNTLEY – Police in Huntley are still trying to piece together events that led to the shooting death of 48-year-old Robert Grundei, but they believe the deadly Memorial Day fight began over living arrangements.

Grundei was in Huntley from Coral Springs, Florida, to mourn the loss of his youngest brother, Brian, who drowned earlier this month in Lake County, authorities said.

Robert Grundei and his older brother, 50-year-old Mark, on Monday began arguing over living arrangements. Mark Grundei lived with their 81-year-old mother, Alyce, at 11469 Morning Glory Lane in Sun City. The house recently had sold, and Robert Grundei was going to live with Alyce, and Mark was going to leave, authorities said.

“From what it sounds like there was some sort of argument about that,” Huntley Deputy Police Chief Michael Klunk said.

Police said at least five shots were fired. Robert Grundei was shot in the shoulder and head and later died from his injuries.

Mark Grundei sustained a gunshot wound to the head that was believed to be self-inflicted. He remains in critical condition at Advocate Sherman Hospital.

An autopsy for Robert Grundei is scheduled for Wednesday morning in Kane County.

Just after 5 p.m. Monday, Alyce Grundei called police saying that she had been shot, and that shots were still being fired. She suffered a graze wound from a bullet and was treated and released at the hospital.

Alyce met officers outside her home and was holding the .38 caliber revolver when police arrived. She told them her two sons were inside and had been shot.

Mark Grundei is believed to be the shooter, though no charges have been filed and authorities said the investigation is ongoing. He purchased the weapon in 2005 and had a valid firearm owners identification card, Klunk said.

The only other police contact at the 11469 Morning Glory Lane home was on May 16, when Lake County asked Huntley officers to deliver news that Brian Grundei had died, Klunk said.

Neighbors on Tuesday said the cul-de-sac street of Sun City Huntley is typically quiet and were shocked by Monday’s violence.

A woman who didn’t want to be identified but lives across the street from the Grundeis said she didn’t notice any disturbance Monday night until she heard the sirens and the police rang her doorbell.

“It’s especially bad for Alyce because she lost her husband a few years ago. I understand she lost another son not too long ago,” said the neighbor, who only knows the family casually.

“It’s a terrible tragedy.”

This is the second violent death in recent years in Sun City, a neighborhood marketed to retired seniors. Robert Signorile is serving a 40-year prison sentence for the 2012 murder of his girlfriend, Michelle Mathieu.
