Toni Hartzong

Do you know how long he stayed that day at the job site?

About 3 o'clock, 3.30.

Do you think they were lying or mistaken?

Remember, police say the murder happened around 1 p.m.

in Jupiter, 43 miles north of Del Rey.

Bob's lawyer, Barry Maxwell, says it's a stretch to believe Bob could have pulled it off.

Witnesses place him in Del Rey at various times in the morning and the afternoon.

So bottom line, in order for him to have left the construction site, headed back home, which is a good 45 minute drive away, commit the murder, clean himself up, drive another 45 minutes back to that Delray Beach construction site, Superman couldn't have done that.

He would have had to flown like Superman.

And as for Bob's blood under Tony's fingernail, Maxwell cross-examines the blood expert.

And from your analysis, ma'am, can you tell this jury how long

This sample of Mr. Hartsong's blood DNA was existing underneath the left nail of Mrs. Hartsong.

We're talking a husband and wife married for 27 years.

We don't know when that blood was placed under that fingernail.

We don't know if it was the morning of, a couple mornings before.

You know, let's talk about this blood.

Maxwell tells jurors there could be all kinds of explanations.

How do we know Mr. Hartsong didn't cut himself shaving a couple days before?

Oh, Mrs. Hartsong, oh, honey, you got some blood.

Let me wipe that.
