The mother who was critically injured in a fatal fire last week In Elizabeth, that also took the lives of her two young daughters and two others, has passed away from her injuries, according to Elizabeth spokeswoman Kelly Martins.

Martins says Merlyn Vasquez, 36, died Thursday. She was taken to a hospital on Oct. 5 following the fire that broke out in a commercial building on the 800 block of Elizabeth Avenue.

Two of Vasquez’s daughters, identified as Daniela Marquez, 8, and her sister, Paola, 10, died in the second-floor furniture store after a fire erupted below. Their friend, Elizabeth Correas, 11, also died. Another woman, Candida Martinez-Del Reyes, was also found dead.

Elizabeth Mayor Christian Bollwage says the victims were inside the store shopping when it is believed that a fire sparked inside a soda machine. The mayor says that employees tried to put it out with a fire extinguisher. When that didn't work, they called the fire department.

The victims tried to flee but were impeded by a metal cage that blocked their escape through a back door, officials said. Bollwage says that at one point there may have been a fire escape at the back of the building, but it was unclear when it was removed.
