Toni Hartzong

Convinced Bob was lying and convinced they had the DNA evidence to prove it, the Cole case squad came to an inescapable conclusion.

Detective, who do you think killed Tony Hartzong?

Her husband, Robert Hartzong.

In September 2006, Bob's quiet new life with Susie got a jolt.

Bob was arrested for the murder of his wife, Toni, six years earlier.

Then he was held without bail for 20 months as preparations for his trial dragged on.

Yes, sir, I sure will.

In May 2008, Bob was released, but he was far from free.

he was sent home and kept under house arrest, wearing an ankle bracelet.

The whole concept of killing somebody, of harming somebody else, is just beyond me.

Is it even conceivable in your mind that Bob could be guilty of the murder for which he's accused?

Finally, in September 2008.

You ready?

I'm ready.

Nearly eight years to the day after Tony's murder.

This is the most difficult day.

Bob is headed to court.

Tony's cousins arrive at the Palm Beach County Courthouse, hoping for some resolution.

Prosecutor Barbara Burns will try to convince the jury that Bob is the murderer.

Is Bob Hartsong a cold-blooded killer?
