ALLSTON, Mass. (WHDH) -- Two people were forced to jump from a 3rd story window in an Allston home to escape a raging fire.

“She couldn't wait for the ladder to arrive at the window. She jumped trying to jump on to the ladder. She missed, fell to the roof you see behind me and bounced off of there and landed on top of a lieutenant from ladder 14,” said Deputy Chief Stephen Dunbar of the Boston Fire Department.

The woman, and the firefighter she fell on, were both rushed to the hospital.

Boston fire officials said there were nine people inside the home at the time of the five-alarm blaze.

All escaped, but three of those residents were taken to the hospital for smoke inhalation.

Most neighbors on Quint Avenue were asleep when the fire broke out around 6 a.m. Saturday.

“First, I didn’t know what was going on, and I looked out my window when I got upstairs and the whole place was on fire at that point,” said Evan Tuohey, who lives next door.

In addition to the woman who jumped from the third story, a man also jumped from the second floor. He too, was rushed to the hospital. Firefighters were positioning a ladder when the residents leaped.

“Thick blinding smoke, they couldn’t even see the back of the building, but they threw a ladder up to the third floor window,” said Deputy Chief Dunbar.

All the residents are renters and are now being helped out by the Red Cross.

According to the Boston Fire Department, the woman who jumped from the third floor remains hospitalized with serious injuries.

The lieutenant she landed on suffered a back injury and was treated and released, but will remain off-duty for the time being.

The cause of the fire is still under investigation.
