Four family members were killed in an apparent murder-suicide Tuesday in unincorporated DuPage County, according to multiple law enforcement sources.
The bodies were found at a house on Oldfield Drive, just yards from a home where three members of a Darien family were shot to death three years ago.
DuPage sheriff's officials declined to comment on the nature of the deaths because of an ongoing investigation but confirmed four bodies were found about 3:30 p.m. Tuesday. Sheriff's spokeswoman Dawn Domrose described the situation as an "isolated incident" and said the public is not in danger.
Officers were responding to a report of a disturbance when they made the discovery, Domrose said.
The house is just north of the Darien border and one street away from the home where Lori and Jeffrey Kramer and their 20-year-old son, Michael, were fatally shot in February 2010 by Jacob Nodarse, who has since been convicted of the murders.
Co-defendant Johnny Borizov, who was accused of masterminding the Kramer slayings, was convicted last month after Nodarse testified against him.
State's Attorney Bob Berlin declined to comment on Tuesday's deaths. He said the sheriff's office was leading the investigation.
"Obviously, we'll cooperate with the sheriff and give whatever assistance they need as far as any search warrants or other help," he said late Tuesday.
The tragedy hit close to home for neighbors in the otherwise quiet residential community, where surviving members of the Kramer family still reside.
"It's just sad stuff like this would even happen," said Lauren Ramski, 21, who lives in a nearby subdivision and gathered with about 15 other neighbors at the scene.
Neighbors said police knocked on doors about 3:30 p.m. and told them to go into their basements and lock their doors. They did not report hearing commotion or gunshots and said officers returned about 15 minutes later and told them it was safe to come out.
Janet Viane, who lives next door the Kramers, described the area as a "phenomenal neighborhood" with a "wonderful support network" that would pull together.
"This had nothing to do with Darien," she said.
Viane said it was a difficult time to face another tragedy.
"We finally get peace for this wonderful family (the Kramers), and now this poor family has been decimated," she said.
The identities of the shooter and victims were not immediately released.
