(CBS) DARIEN, Ill. - Four people were found shot to death Tuesday at a suburban Chicago home in what appears to be a triple murder-suicide, according to CBS Chicago.
The station reports, a preliminary investigation indicated that a man shot his wife and two daughters at the home and then shot himself.
According to the Chicago Sun-Times, the bodies of David Andrus, 50, his wife, Jeana, 48, and their daughters Jessica, 22, and Jennifer, 16, were found inside the DuPage County home by police officers after they received a disturbance call on Tuesday.
A county sheriff's spokesperson reportedly said that area residents do not need to be concerned with their safety as it appears to be an isolated incident.
On Tuesday night, police reportedly walked door to door in the neighborhood to find clues that might reveal what happened. The investigation is ongoing.
A neighbor told the Sun-Times that a relative was in the house at the time of the shooting.
CBS Chicago reports that in 2010 a similar incident took place just a block away when a mother, a father and their son were shot to death.
