Potential evidence and interviews you have not heard.
That's what 48 Hours Mystery promises in Saturday's program, "A Time to Kill."
It explores the disappearance of Michele Harris, and the suspicion surrounding her husband, Cal, in Tioga County.
Reporter Erin Moriarty tells us what 48 Hours will reveal.
"He comes across as personable and cooperative. To me, it seems like there's just something missing."
Cal Harris denied he had anything to do with Michele's disappearance, instead he told investigators to take a closer look at Michele herself.
"Is there any different sense of him that you think this 48 Hours mystery brings about what he's been going through in this process?"
"Oh, absolutely I think so. We speak to both of his defense attorneys who do a very good job of telling his side of the case. We have an equal number of people who explain the prosecution and evidence against him. But this is really, right down the middle."
"Then, a major break in the case. A forensic clue that would lead police to a possible crime scene."
"We had blood spatter in the house."
"For people who have been watching this case very closely, can you give us an idea of why, when they watch this, why they are going to learn something new or what they might learn something new about?"
"We talked to people who have not spoken previously and that's in this hour. We also spoke with people who brought up what could be considered evidence that did not come in the trial."
"Because of some of the coverage in the local newspaper there was some confusion about the verdict. I think this hour when you take a look at the entire case, we talk to a number of the jurors afterward and how they reached their decision. I think it will clear up a lot of confusion about the case."
As this case goes forward, if there is a new trial, something 48 hours will continue to follow?"
"We will definitely follow this case. You know, there is no way of knowing how its going to turn out. It's an important case for a number of reasons. Legally, because prosecutors look at this type of case to see whether they will in fact take another case where there is no body and very little evidence.
"But also there is this woman who is still missing, more than 6 years later, Michele Harris."
"She was loved by a number of people. She had 4 wonderful children and I think if anything else one of the reasons why we will follow up is because Michele Harris is still gone."
Moriarty says bringing national attention to the case could help, if someone, somewhere has information about what happened to Michele Harris.
Cal Harris is out on bail until a decision is made about a new murder trial.
The Tioga County District Attorney is appealing a judges decision to throw out the guilty verdict.
48 Hours Mystery, A Time to Kill, airs Saturday night at 10:00 pm here on WBNG-TV.
