(ABC 6 News) – The Minnesota State Fire Marshal is assisting the Rochester Fire Department’s investigation into a deadly house fire in the northwest part of the city Monday night.

According to RFD, the fire happened at a home on the 2200 block of 49th Street NW, with callers telling dispatchers they heard an explosion.

Virginia Allie was watching TV barely a block away when she heard the explosion.

“We were thinking maybe somebody drove into our house it shook it so bad,” Allie said. “Then we discovered when we came out the back door that this house was on fire.”

The victim, an adult woman, was found outside the home, but died inside a Mayo Clinic Ambulance on the scene. No other victims were found inside the house. Further information about the victim and her identity will be released by the Medical Examiner.

Fire crews began extinguishing the fire from outside before moving in. Operations were slowed over concerns about the integrity of the main floor, but crews moved in again once it was determined to be safe.

The house itself sustained fire damage throughout its structure.

The cause of the fire remains unknown while fire marshal’s investigate.

In the meantime, the neighborhood waits for answers.

“You know just hoping that it wasn’t something that would trickle down to the rest of us, I didn’t know what was going on,” Allie said. “Hopefully it was something that the family of the victim can you know find out as well.”
