Five people were found dead with gunshot wounds in a house in the north Chicago suburb of Mundelein overnight Sunday into Monday.
At 11:45 p.m. Sunday, Mundelein police were called for a wellbeing check at a house in the 200 block of Wellington Avenue.
Inside, officers found three men and two women dead. All five had suffered what are believe to be gunshot wounds, police said.
The five adults were either family members or in a domestic relationship, police said.
Two handguns were found at the scene.
Mundelein police were investigating Monday morning along with the Lake County Major Crimes Task Force. Police said the incident appears to be isolated and there is no threat to the public.
CBS News Chicago was on the scene as investigators brought out three bodies on stretchers around 7 a.m. Each was covered in a black sheet.
The bodies were taken placed in a black van.
Some time afterward, investigators were seen trying to get inside a Volkswagen with Illinois plates. The vehicle was sitting in a funeral home parking lot that butts up to the red house.
The car was wrapped up in crime scene tape, as it had been all morning long. The car's relevance o the death investigation was unclear.
The names of the dead had not been released as of 9 a.m.
Neighbors said a retired couple who used to run a veterinary clinic lived in the house. They said the family was quiet.
A neighbor who did not want to be named fears one of the victims might be the female homeowner.
"She'd say hello to people. She was friendly," the neighbor said. "I have a cat who comes out and runs around as I'm gardening, and she'd always talk to me about my cat. She knew cats. She loved cats."
Police have not released any motives or said who may have pulled the trigger and killed the people in the house.
Anyone with information on the incident is asked to call Mundelein police at 847-968-4600.
