Elderly woman in critical condition

After Wednesday night's blaze in Sherman, more details are becoming available.

The fire started around 7:00 p.m. at the Hilltop Village Apartments across from Midway Mall. An elderly woman who was hurt is in critical condition at Parkland Hospital in Dallas. Firefighters suspect the fire started in her apartment but aren't saying exactly how it happened.

Firefighters also credit the bravery of bystanders for pulling people to safety.

Sherman Fire Chief Jeff Jones said an oxygen tank could have played a role in the fire. They are waiting to speak to the elderly woman, who's expected to remain in the hospital indefinitely.
