Firefighters found Judy Reifel unconscious in her low-rise garden apartment on Rennie Place around 8 a.m. Friday, Oct. 13, the prosecutor said.
She was taken to Hackensack University Medical Center in critical condition and was pronounced dead there a short time later, he confirmed.
"A preliminary investigation has determined that the fire was accidentally set and does not appear to be suspicious," Musella said.
Responders said an oven fire was to blame.
Arrangements had yet to be announced on Saturday, Oct. 14.
