MUNDELEIN, Illinois, October 20, 2026 â Five people found shot dead inside a suburban Chicago home have been identified as a retired veterinarian couple, their son, grandson and the son’s longtime partner. Authorities are investigating the deaths as an apparent murder-suicide that has shaken the normally quiet village of Mundelein.
The Lake County Coroner’s Office identified the deceased as James Schmidt, 80; Rebecca Schmidt, 77; Bryan Schmidt, 51; Maclaine Schmidt, 22; and Nicole Heiser, 37. Four were members of the same family, spanning three generations.
Autopsy findings indicate Bryan Schmidt died from an apparently self-inflicted gunshot wound. Investigators have not announced a motive or explained what led to the deadly violence.
Five Mundelein Murder-Suicide Victims Identified
James and Rebecca Schmidt were retired veterinarians who lived at the Wellington Avenue home. Their son Bryan had recently lived in Antioch, Illinois, with his longtime partner, Nicole Heiser.
Maclaine Schmidt, Bryan’s 22-year-old son, lived in Lake Bluff.
The elderly couple had longstanding ties to the local veterinary community through Northern Illinois Cat Clinic in Libertyville. Bryan was also involved in the family business, which reportedly closed earlier in 2026.
Neighbors described James and Rebecca as friendly, quiet residents. Rebecca was remembered for greeting people and speaking with neighbors during walks.
Autopsy Findings Reveal New Details About Five Deaths
The Lake County Coroner’s Office conducted autopsies Monday, October 19.
James and Rebecca Schmidt died from multiple gunshot wounds, while Maclaine Schmidt and Nicole Heiser each died from gunshot wounds to the head.
Bryan Schmidt also suffered a fatal gunshot wound to the head, which the coroner described as apparently self-inflicted.
Two handguns were recovered from the property. Authorities have not released detailed ballistic findings or established the precise sequence of the shootings.
California Daughter Requested Welfare Check
Police discovered the bodies late Sunday, October 18, after a relative reported being unable to contact a family member.
Local television reports identified the concerned relative as Kimberly, the elderly couple’s daughter, who lives in California.
At approximately 11:45 p.m., Mundelein officers responded to the residence in the 200 block of Wellington Avenue.
They entered through an unlocked door and found three men and two women dead in different rooms.
Investigators have not confirmed exactly when the shootings occurred.
Neighbors Recall Possible Gunshots Before Bears Game
