Walther was deployed behind the house to check for smoke. While waiting there for his partner to come with a ladder, something clicked when he saw the screened-in back porch.
"I realized this guy was going to be on the first floor," said Walther, 37, a five-year veteran of the Fire Department.
He broke down a door and was confronted with thick smoke and zero visibility.
He crawled into the kitchen on his stomach.
"I realized I was shining the light of my flashlight through the spokes of a wheelchair," Walther recalled.

Walther pulled the 90-year-old victim out of the building.
At that point, the elderly man went into respiratory arrest. He was whisked to a hospital
