It caught a glimpse of an SUV pulling into the subdivision shortly before the fire.

It was a little blurry.

It was a few seconds long, but it sure looked like Keith Griffith's car.

Certainly not an unknown intruder.

The dog and Keith were very close, but a burglar couldn't have come in.

A family member could have.

As for the why question, how could Keith, a man who by all accounts loved his wife, actually do it?

Well, the prosecutor turned to two age-old motives.

Almost every case involving a husband and a wife, it's lust and greed.

One or the other.

And this one had both.

The lust part of the equation, he said, was Deanna.

She took the stand and told the jury that not only was Keith house hunting for them, he was also making plans to bring her down to Paducah for a concert and introduce her to his family.
