KATIE KATRO: And wrecking crews are back out here again this afternoon. You can see this demolition crew here. They are loading up bricks from the home into this truck, and if I pan you all the way to the top of the home, you can see just how much damage was done from that explosion.

- I heard this incredible boom.

KATIE KATRO: Today, the ATF and Fire Marshal's Office confirms it's looking at videos like this one posted online, which shows the explosion on the 6300 block of Algard Street in Wissinoming yesterday afternoon. Video also shows a good Samaritan rushing to rescue the 61-year-old man trapped inside.

SUSAN SHAWCROSS: People were screaming he's in there, he's in there. Flames were falling. Tiles were falling down. The roof was caving in, but he still ran up there, and that's what he said, he-- we thanked him a million times.

KATIE KATRO: The good Samaritan tells Action News he was there at the right place at the right time. Neighbors say the 61-year-old man, Steve, lived alone.

SUSAN SHAWCROSS: He's a great guy. He has a heart of gold.

During their evacuation of the rubble yesterday, they discovered a bullet hole in the home's gas meter according to law enforcement sources.
