A witness took a picture of Officer Kristi Johnson holding a baby and running out of the burning building.
Arlington police confirm that she and Officer Billy Cruz were working an unrelated disturbance call when they saw the smoke and ran into the building.
The fire started just before 5 p.m., and the officers started going door to door, alerting residents to get out. However, the officers didn't have any breathing equipment, so both suffered smoke inhalation and had to be taken to Medical Center of Arlington.
Four apartments are a total loss. They're all in the same building, which didn't have sprinklers, and it's unclear if the smoke detectors were working.
A dozen people are now homeless and firefighters are trying to figure out the cause of the fire.
Investigators say the strong winds fanned the flames making the fire spread quickly, and it was upgraded to three alarms.
