When responders went into the home, some reported symptoms that included feeling dizziness and burning eyes.
Unfortunately, the woman was pronounced dead.
At the time, the woman's mother and sister were in the home, but they had no symptoms.
Officials cleared the home and hazmat crews were sent in. They took meters of the home four times, but were unable to find anything.
The one officer's symptoms didn't go away, so they were taken to a hospital for treatment.
Originally, there were reports of a possible natural gas leak, but no gas lines are in the neighborhood.
A medical examiner will determine how the woman died.
