The original police report said that Janet Dow's car veered off this road and ended up right here in this ditch.

The impact sent concrete blocks, which had been placed in the back of the vehicle for better traction, flying forward, knocking out both mother and son.

According to Dick Dow, Stephen had placed a carburetor in a bucket of gasoline in the back seat.

Police believed the gasoline ignited, causing the fatal fire.

The engine's been running for about 12 minutes now.

We're just about ready to do this parking test.

To recreate the accident and fire, Bohan and his team found a 1982 Saab, just like the Dows,

and rolled it into this ditch.

We had a similar bucket of gasoline in the back.

We sparked it about 25, was it 25 times?

Nothing happened.

There was no ignition.

The gasoline did not ignite.

There is nothing inside that car that could have set the gasoline off.

There he goes with the flare.

We only got it to ignite when a rag was thrust inside the vehicle and the window was left open for air to feed the fire.

Is it your belief then that the gasoline was ignited by a person?

It was ignited from the outside.

You're convinced of that?

Yes.
