Authorities say a person killed when a fast-moving fire roared through an Essex County home this week has been identified as a woman who lived in a basement apartment.

Essex County prosecutors said 47-year-old Geovanna Mora-Gamboa was the only person in the Irvington home when the fire broke out Sunday night. She was unconscious when emergency crews found her in her apartment. She was pronounced dead at a hospital a short time later.

A cause of death for Mora-Gamboa has not been disclosed. The cause of the fire remains under investigation.
