Perry March

You take your time in it, you don't make any mistakes, you go carefully, you figure through the promises, you do what you need to do.

But despite the incriminating evidence, Perry March's attorney keeps insisting no one knows what happened to Janet March.

That she left the house alive the night she disappeared.

And they have an eyewitness.

She told me that she'd be back soon.

The defense introduces this television interview from 2001 with Perry March's son, Sammy.

She came in, gave me my goodnight kiss, and then I got out of bed and went to the window to wave to her when she was driving away in the car.

The last person to take the stand is Perry March himself.

Perry March.

The man who for 10 years has proclaimed his innocence.

I don't believe my wife is dead.

I didn't do anything wrong.

I have no idea what happened that night.

Suddenly, now, has nothing to say.

I choose not to testify.

After one week of testimony, the jury begins deliberating.

It took 10 years to get to trial.

but it takes just over 10 hours to reach a verdict.

Guilty on all three counts.

The irony is that prosecutors may not have had enough to convict Perry March when they first charged him with murder.
