Mundelein Murder-Suicide Leaves 5 Dead, Including 4 Family Members: Police

MUNDELEIN, IL — Five adults found shot to death inside a Mundelein home early Monday were killed in an apparent murder-suicide, authorities said in an update Monday afternoon.

A preliminary investigation indicates all five people were shot at close range with a handgun, according to the Mundelein Police Department. Four of the deceased were family members, while the fifth is believed to have been involved in a domestic relationship with the suspected shooter, police said.

Authorities have not identified the suspected shooter or released the names of those who died. Police were called to the home in the 200 block of Wellington Avenue, near Prairie Avenue, at about 11:45 p.m. Sunday after a concerned family member requested a well-being check because they had been unable to contact one of the victims.

Responding officers entered the home and discovered five deceased adults. Two of the victims lived at the Wellington Avenue residence, according to police.

The Lake County Coroner's Office is conducting autopsies and working to confirm the identities of those who died.

Police reiterated Monday that the incident appears to be isolated and there is no threat to the public.

"The Mundelein Police Department extends its condolences to the victims' loved ones and recognizes the impact this tragedy has had on our community," police said in a statement.
