Hope would be diminished again when the forensic testing led nowhere.

Still, Joseph Ambrose and Wayne Greaser remained at the top of Frank's suspect list.

In May 1999, Frank decided to question people who knew Ambrose and Greaser around the time of the murder and had been named in prior police reports.

The thought was the passage of time might make someone more forthcoming.

And the investigators took several steps to try to help that along.

In fact, there was no designated HESI task force, nor was it getting hot.

It was just one of the measures taken by Frank and his team as they tried to see if anyone would give new information.

Investigator Jay Peterson.

They also tried to make the setting a bit uncomfortable for those being interviewed.

But despite all those efforts, nothing usable was learned.

So Frank decided it was time to interview Joseph Ambrose himself.

In September 1999, Frank traveled to Orange Park, Florida, where Ambrose was living.

Working with local law enforcement, Frank went to Ambrose's home where he answered the door.

And willingly went to be questioned at the Florida Department of Law Enforcement.

Ambrose said on the day of the murder, he got off work around 5.30, went home, and then went to a club until closing time.

Unlike his previous interview, where his now-deceased friend Wayne Greaser was his alibi, he did not mention being with Greaser.

Frank also asked many questions about Ambrose's job at a slaughterhouse.

Since Mary Kay was stabbed to death, Ambrose was asked about his access to knives.

Ambrose was adamant he had nothing to do with Mary Kay's murder, even when Frank implied they found someone's DNA at the scene.

Despite Ambrose's cooperation, Frank found several things suspicious, like Ambrose's explanation for giving different versions of where he was at the time of the murder.
