Woman dies walking up to 19th floor Co-Op City apartment during outage

A 73-year-old woman died while walking up the stairs to her 19th-floor apartment during a power outage, the NYPD said, adding that an empty oxygen tank was found next to her.

Ada Longmore was found dead Friday afternoon between the 18th and 19th floors of her apartment building in the Co-op City section of the Bronx, authorities said. Police said there were no signs of foul play.

The building, and its elevators, lost power Friday morning because of a transformer fire. Electricity was restored Friday night.

Longmore's daughter, Andrea Longmore, told the Daily News that her mother suffered from a lung sickness for the past year.

"She was a very happy soul, always finding joy in the simple things of life," Andrea Longmore said. "She was a family-oriented person. She was very resilient and strong and able to keep her family together."
