Thousands of people lost power during a major outage Sunday at Spring Creek Towers, and a woman was found dead at the complex during the outage, although it's unclear if the death was related.

Power has since been restored to the complex's 40 buildings that house 15,000 residents, many of whom are seniors. The outage began around 5 a.m.

Three people were injured during the outage, and officials reported one death, although it wasn't immediately clear if the outage was the cause.

Elizabeth Ramos, 57, was identified as the deceased person. Her family says she was attached to a portable respirator that apparently stopped working when the power went out.

They say Ramos suffered from a lung disease and depended on her machine. Her daughter says her mother had voiced her concerns about the constant power outages. 

Spring Creek Towers experienced a previous power outage almost a year ago and in the past four months they have lost power four times.

"She was on News 12 Brooklyn before speaking about this and she is an advocate for people with disabilities so she tries to fight for all these things," said Elizabeth's daughter, Ashely Ramos. 

News 12 Brooklyn interviewed Elizabeth Ramos a year ago about not having air conditioning in her apartment for two summers. She said she was nervous the power she depended on in her building would go out.

Elizabeth's family hopes that the situation will force the building to take quick action in resolving their power problems even though the fire department claims that Elizabeth may have died from other causes. The fire department says they will be conducting an investigation into the matter. 

Over 150 firefighters responded to the outage, rescuing five people who were stuck in elevators and going door-to-door to check on residents.

Three people suffered minor injuries, while two others refused medical attention.

Spring Creek runs on its own power supply. Officials say they plan to install permanent backup generators and new equipment for the power plant this September.
