Toni Hartzong

And there are more forensic questions that investigators never answered.

That unknown fingerprint on the deadbolt lock and bloody footprints in the house that the original detective on the case could not identify.

Well, to the best of your knowledge, have we ever matched the footprints walking through the home?

No.

And then there is Ronald Gagnon, a schizophrenic homeless man seen near the Hartsong house around the time of the murder.

He left Florida soon afterwards.

Investigators tracked Gagnon down in California, where local police interviewed him.

Have your voices ever told you they killed somebody?

Mm-hmm.

Gagnon mutters incoherently in this police video, talking vaguely about hearing voices and dreaming about murder.

You think he might have killed somebody?

California police claim that off-camera, Gagnon talked of details that police say might be related to Tony Hartzong's murder.

Details they reported to Palm Beach County Detective David Bradford.

Mr. Gagnon talked about a blonde woman, correct?

That's correct.

Mrs. Hartzong was blonde, wasn't she?

That's correct.

Mr. Gagnon talked about the blonde woman being stabbed, didn't he?

Yes, he did.

I don't have any other questions, Judge.
