Chilling new details have emerged of the night a Wisconsin couple was gunned down and their teenage daughter abducted.

It is nearly two months since James, 56, and Denise Closs, 46, of Barron, Wisconsin were shot dead and 13-year-old Jayme taken from their home.

Now Barron County Sheriff Chris Fitzgerald has shared troubling new information with DailyMailTV about the crime that took place on October 15 and has stunned the small town.

He has revealed the bizarrely ordered crime scene in which nothing was out of place despite the violence of the attack.

He has described the speed and lethal accuracy with which the killer executed his victims then vanished without trace. He has told of the one key piece of evidence for which investigators are searching.

And he has admitted that they may have already interviewed Jayme's captor and her parents' killer.

Police revealed the killer was in the Closs home for only four minutes during which they stepped five feet into the house, shot James and Denise and took Jayme

Barron County Sheriff Chris Fitzgerald (pictured) told DailyMailTV nothing was out of place at the crime scene, which is 'part of the confusing part of this case'

Fitzgerald said: 'The house wasn't disturbed at all from what we were able to tell. That's part of the confusing part of this case.

'It doesn't appear that anything was taken, it doesn't appear that Jayme packed up any clothing.'

Law enforcement has not ruled out that Jayme unwittingly played a part in the crime. But searches of her social media, cell phone and computer have offered no evidence of a boyfriend or anyone she met anyone online who might have targeted her or her parents.

According to Fitzgerald the killer was in the Closs home for only four minutes during which they stepped just five feet into the open plan house, shot James and Denise and took Jayme.

Both Denise and James died 'instantly' of their wounds, he said.

And, despite an inaudible 911 call made from her mother's cell at 12.54am, when police arrived at 12.58am he revealed that there was no sign that Jayme resisted her abductor. There was nothing taken and nothing disturbed.

In fact there was no forensic evidence of any intruder at all.

The sheriff said: 'That's the frustrating part of it. We've had four different lab teams look at the scene before we released it. We were very strategic. When we discovered it was a major crime we sealed it off immediately.

'But if I'm in your house for minutes and I only step five feet inside your home I'm probably not going to leave a big footprint.'

All that the shooter left behind was the bullet casings from the rounds fired. Fitzgerald would not say how many or what caliber of gun was used

All that the shooter left behind was the bullet casings from the rounds fired. Fitzgerald would not say how many or what caliber of gun was used.

He said: 'Only the killer is going to know that and that's information we have to hold close to the case so that when we catch this person we can convict them. We are looking for that gun. We are looking for a firearm.'

When Jayme first went missing more than 200 law enforcement officers were tasked with tracking her down and finding the Closs' killer.

But despite the combined efforts of the FBI, State Police and Sheriff's Department and a $50,000 reward for information leading to an arrest or Jayme's discovery, investigators still have nothing more concrete than hope to suggest she's still alive.

It is a desperate hope shared by her family.

Speaking to DailyMailTV, Jayme's aunts Jennifer Smith, 47, and Suzy Allard, 50, were adamant that Jayme will be found and revealed their belief that she is being held locally.

Jennifer said: 'I feel that she is alive and she is close by. I just feel it. I do truly believe somebody out there knows something.

'I think someone in Barron is keeping a secret, yes, I do.'

But for the most part the family can't be certain of anything. In the weeks since the horrific events they have been forced to question everything.

Jennifer admitted: 'We've had to be open to things not being what they seemed. We just don't know.

'We don't know if someone got the wrong house, was it a case of mistaken identity, was someone mad at James or mad at Denise or were they after Jayme?'

According to the family Denise and Jayme were 'inseparable' but they describe a certain disconnect between James and the rest of the family.

He often arrived at events in a separate car as he often left early while Denise would be the last to leave.

There had been a family birthday party the Sunday before the shooting. Jennifer recalled Denise brought bags of candy for the children and seemed her usual social self.

Jayme was 'on the quiet side.' But then she often was. James did not come, as he had to work.

The last image Suzy has of her sister Denise is of her turning and giving a 'huge wave' as she got into her car to take Jayme home.

Both sisters spoke with her later that evening and she was making plans to go Christmas shopping and visit a newly opened toy store.

They describe James as into sports, a man who loved the Packers and grilled steak every Sunday.

As a couple James and Denise kept to themselves, mostly staying at home with few visitors.

But there is nothing that the family can think of in either of their lives or histories that might help make sense of what happened.

Jennifer said: 'They had both been married before but there was no bad blood there.'

Both she and Suzy dismissed the suggestion, circulating locally, that Denise was having an affair and that a scorned lover carried out the attack after she called it off.

'No,' Jennifer said, 'I'd have known. We spoke all the time. She came over two or three times a week.'

Nor can the sisters think of anything that links the Closs family to this corner of Wisconsin's rampant methamphetamine problem.

Suzy said: 'There's just nothing. But you think and think. It never stops. We're not sleeping much, Jayme's on your mind all the time. It doesn't make any sense.

'We just have to focus on getting Jayme home and after we do we'll have to help her, that's the next step.'

Only when she's back, they said, would the family be able to mourn the loss of Denise and James.

Suzy explained: 'We need that closure.'

Today the investigation has been scaled back to around 30 officers. Experts are piecing together surveillance footage from more than 80 cameras covering the area surrounding the Closs family home.

But Fitzgerald admitted that they are 'not excited' by what they have seen so far.

'The cameras aren't trained on the road,' he said, 'And they didn't stop at a gas station to get a soda or anything like that.'

The red Dodge Charger or Challenger cops had pointed to as a vehicle of interest has now been excluded from inquiries and none of the 2,300 tips followed up and closed out have led anywhere.

Investigators in Jayme's disappearance have begun re-interviewing people and working back through interviews already conducted in a bid to find any inconsistencies

'People have started comparing this to Jacob Wetterling,' the sheriff admitted.

It's an uncomfortable comparison. Eleven-year-old Wetterling was abducted from his home in St Joseph, Minnesota, in 1989 when he, his brother and a friend were cycling home from renting a video.

His disappearance remained unsolved for 28 years until his killer - arrested on child pornography charges - cut a deal, confessed and led police to the boy's body.

It turned out police had interviewed the killer two months after Wetterling's disappearance and let him go.

With this in mind investigators in Jayme's disappearance have begun re-interviewing people and working back through interviews already conducted in a bid to find any inconsistencies.

Meanwhile the FBI has provided not one but four psychological profiles of the possible killer depending on who the target was: Denise, James or Jayme.

But the truth is that without knowing who the target was investigators don't really know what crime they are trying to solve.

Fitzgerald admitted: 'It is very frustrating. It's lots of ups and lots of downs and the downs hurt because you think ''We're going to get her. We're going to find her. We're going to solve this case.'' And then it doesn't happen, or that tip isn't true.

'It really stings. But you just have to keep believing and keep that hope alive that we'll bring Jayme home.'

Anyone with information on her whereabouts or anyone that has contact with Jayme is asked to contact the tip line 1-855-744-387.
