The Addison Police Department is investigating a murder-suicide at a home in the village.

Responding to a 911 call, police found a man, a woman and two boys dead when they arrived at the home about 6:30 a.m. Wednesday morning, officers said.

At a Wednesday afternoon press conference at Addison Village Hall, Addison Police Chief Tim Hayden said police responded to the home after 911 dispatchers received a phone call for help from someone in the house.

“The caller made some sort of statement to the effect that she needed help,” Hayden said.

Officers had to force their way into the house, which Hayden said was secured. One victim was found on the first floor, and three victims were found on the second floor.

“Most likely, they are the family that lived at the residence,” Hayden said.

Hayden said the motive is not known and that murder-suicide could be one of the possible areas where the investigation leads.

“The neighbors don’t have to be concerned because, like I said, the house was secured,” Hayden said. “In my opinion, it’s not a random act of violence.”

Investigators have found shotgun shells on the property. Hayden said that the location of the shells indicated that they were shot at some of the victims.

Addison Elementary School District 4 Superintendent John Langton told reporters that although a positive identification has yet to be made of the bodies, children who live within the house would have attended either Fullerton Elementary School or Indian Tails Junior High School.

Hayden said police will not release the identities of the dead because that is the role of the DuPage County Coroner.

Police remained on the scene Wednesday afternoon. Officers said no motive has been established and the case is still under investigation.

“Preliminary investigations indicate this incident is isolated to this address, therefore area residents should not be alarmed further acts of violence will occur as a result of this incident,” the Addison Police Department said in a news release.

The street was blocked off and police tape surrounded several homes on the block Wednesday afternoon. Neighbors gathered outside to recall memories of the family they characterized as nice and normal people.

John Kruse, a resident of 11 years, lives three houses away from the scene of the murder-suicide.

“They seemed like a typical, normal family,” Kruse said. “Everybody seemed happy.”

Eight-year resident James Vega echoed similar sentiments.

“I would see the kids outside playing,” he said. “I didn’t notice anything out of the ordinary.”
