Original story published May 27:

A suburban family that had gathered to mourn the death of one brother now has a second brother to mourn and a third — who police say shot the second brother — in critical condition after a fight erupted in Huntley Monday. Their mother was also injured in the shooting.

Brian Grundei, the first brother to die, was found dead in a pond at a Deerfield subdivision earlier this month. He drowned, though police and the coroner have yet to determine if it was an accident or suicide.

His family gathered in Huntley over the long weekend to mourn him when the shooting happened, according to the Daily Herald. Police told the paper that Mark R. Grundei, 50, shot Robert Grundei, 47, in the head and shoulder around 5 p.m. Monday, killing him.

Police found Mark with a gunshot wound to the head, which appeared to be self-inflicted, according to an article in TribLocal. The Herald story says he's listed in critical condition.

The men’s mother, Alyce Grundei, 81, was grazed by a bullet while trying to break up the fight, according to a CBS Chicago article. She called police to report the shooting.

Alyce and Mark Grundei live together in the home where the shooting occurred, the Daily Herald reports.

Robert Grundei had traveled from Florida for the funeral.
