The DeKalb County fire marshal declared six units in the townhome complex unsafe to live in. The declaration was made due to structural damage and fuel vapor.

Channel 2's Audrey Washington said she found pieces of the plane about 500-feet away from the crash scene.

Channel 2's Aaron Diamant was one of the first reporters at the scene as emergency crews gathered and responded to the crash site.

Weather was not good at time of crash

Severe Weather Team 2 Meteorologist Brian Monahan said visibility at the time of the crash was around 3 miles. The ceiling (cloud base) was just 400 feet.

Officials have not determined what caused the plane to go down.

The National Transportation Safety Board is investigating the cause of the crash.

Witnesses describe the crash

There were many people in the area who saw and heard the plane go down.

David Youngpeter lives near the crash scene and said he felt the crash.

"I actually felt the reverberation from the impact at which point I came outside," Youngpeter said. "The first thing is it didn't look like a plane because there's nothing left. It must have been a very small plane."

Neighbor Stephan Kohou said he will never forget this day.

"I would never imagine something like that happening and it's really sad," Kohou said.

Neighbor Jared Hauck said he raced out his home when he heard the crash.

"I was very surprised, because I actually walked out my front door and there's a piece of a plane sitting in front of the door," Hauck said. "It really could have just as easily been me. I mean, it must have broken apart in the trees directly in front of my townhouse."
