CHANNAHON, Ill. (AP) - Three children and a woman were found shot to death Thursday morning in a sport utility vehicle parked on a road just off an Illinois highway, authorities said.
A man who also had been shot was taken from the SUV to a nearby hospital with non-life threatening injuries, Channahon Mayor Joe Cook said.
Authorities did not release their identities.
No one was in custody, but Cook said it appeared to have involved domestic violence.
Channahon police found the SUV on a service road near Interstate 55, north of the Des Plaines River, about 40 miles southwest of Chicago.
A woman who lives nearby said she heard several loud cracking sounds shortly before 10 p.m. Wednesday and again about five minutes later.
"I was in bed and I thought it was in my backyard it was so loud," Debra Walick said.
She said she got up to investigate after the second set of shots, but returned to bed. Thursday morning she saw police in the area.
"I am still a little shaken," Walick said. "I wish I had reacted differently. I don't think I could have prevented what happened. But perhaps they would have been found earlier."
