"We don't believe that the offender is among the victims right now," Burne said. "It is not a murder-suicide."
Burne added that the department is "not actively looking" for suspects in the area, and that they are not asking residents to shelter in place.
"There is no ongoing threat due to the time frame that has gone by; more than 18 hours from the time we were contacted," Burne said.
According to officials, the incident is believed to have occurred between 9 p.m. Saturday and 5 a.m. Sunday morning, and the investigation remains active.
"The investigation is still in its early stages," Burne said, adding that police were not expected to hold further updates Monday "due to the sensitivity of the case and to maintain the integrity of the investigation."
Romeoville, in Will County, is located approximately 30 miles southwest of Chicago.
