Fire officials say crews were first called to the home in the 200 block of North Elm around 5:30 a.m. It took 2 to 3 hours to get the fire under control.
Investigators would later confirm four people died in the fire, including a couple, their granddaughter and her boyfriend. Their names won’t be released until at least Friday.
Fire investigators say 3 cats and a dog also died in the fire.
Although the cause of the fire doesn’t appear to be suspicious at this point in the investigation, a K-9 unit will be brought to the area Thursday evening to help determine a cause.
The preliminary investigation revealed there were no working smoke detectors in the home, and an elderly man who lived at the home was a heavy smoker.
An official cause of the fire is yet to be determined.
Winter weather conditions were also a factor during the response. Some water lines froze, along with fire hydrants.
