MARCH 26 10:08AM  |  A woman and her four-year-old daughter were critically injured and two dogs died in a two-alarm fire in a Long Beach apartment early Thursday morning, authorities said.

Long Beach Police Department (LBPD) units in the FOX helicopter were patrolling the vicinity at about 12:05AM when they noticed heavy amounts of smoke coming from a structure in the 1000 block of Stanley Avenue.

Long Beach Fire Department (LBFD) Engine 10 personnel responded to the scene at 12:09AM, said LBFD spokesperson Jake Heflin.

Upon arrival, they found heavy, thick, black smoke coming out of a third story unit, and a second alarm was called.

As units made their way up to the third story, the engine captain saw residents of the complex trying to break a window that led to a bedroom in the involved apartment.

Firefighters forced entry into the apartment and made their way to the bedroom, where they saw a 47-year-old woman and her four-year-old daughter lying on a bed while unconscious and unresponsive.

While four residents live in the unit, only two — the woman and her daughter — were home at the time of the fire, Heflin said. The woman’s husband and her sister were not home at the time of the fire, Heflin said.

The woman and her daughter were transported to a local hospital in critical condition. The girl was later transported to a burn center in Torrance.

“They were in absolutely critical condition,” Heflin said. “This is just a tragedy.”

The four residents were displaced. The American Red Cross was called in but it is unknown if the family accepted their assistance with finding temporary lodging.

The fire was knocked down at about 12:20AM by about 50 firefighters, Heflin said.

Residents in nearby apartment units had to be evacuated while firefighters battled the blaze, but were able to return to their homes once it was determined safe.

The affected unit, where the fire remained contained, was considered a “total loss,” Heflin said.

The cause of the fire is under investigation. Heflin said the unit did have smoke detectors installed, but it is unknown if the alarms were activated.
