The missing 13-year-old Wisconsin girl whose parents were found dead inside their home may have been spotted at a Miami gas station, police have revealed.

A person reported that a girl resembling Jayme Closs was seen at a Sunflex gas station on Monday with two Middle Eastern men who appeared to be in their thirties.

The men were described as being about 5ft 7in and 5ft 9in and weighing around 200 to 250 pounds. They both had beards. Authorities said they were well-dressed.

They were spotted driving a black Ford Explorer with the Wisconsin license plate tag of I60WER between 2 to 3pm.

Jayme's parents Denise Closs, 46, (left) and James Closs, 56, (right) were both found dead inside their Barron home on Monday around 1am

Police said the details came from a witness account and that authorities have not yet confirmed the reported sighting.

'We are actively researching that tip. Every tip continues to be followed up on,' Barron County Sheriff Chris Fitzgerald said during a press conference on Tuesday.

Barron to Miami is approximately 1,752 miles away and around a 25-hour drive.

Jayme was first reported missing after officers were summoned to her home in Barron just before 1am on Monday.

Fitzgerald revealed on Tuesday that someone called 911 from a cell phone while at the home, but no one was communicating to the dispatcher.

'Some kind of disturbance could be heard, and that's why law enforcement came to the house,' he added.

It was there that responding deputies discovered Jayme's dead parents, Denise Closs, 46, and 56-year-old James Closs.

Fitzgerald said gunshots had been fired at the home, but would not yet confirm whether the couple had been shot.

Barron County Sheriff Chris Fitzgerald said Jayme was not considered a suspect in her parents' deaths and that he believed she was in danger

Jayme had last been seen at a family gathering on Sunday afternoon.

Robert Naiberg, Jayme's grandfather, said she had been 'quiet as always' at his grandson's birthday party.

Naiberg said Jayme was a 'thoughtful person' and had brought a 'little gift for everybody' to the party.

Jayme's father was working at the time of the party, he added.

Fitzgerald said Jayme is not considered a suspect in her parents' deaths and that he believes she is in danger.

He also declined to elaborate as to why investigators believe Jayme is not a runaway, saying that disclosing more information would compromise their investigation.

'At the end of the day, I want a 13-year-old here safe and sound,' he said during a press conference on Monday.

'That's our goal. That's our only goal right now.'

An Amber Alert for Jayme was issued on Monday, although it did not include any information about a suspect or vehicle.

The Barron County Sheriff's Office has also enlisted the help of the National Center for Missing Exploited Children and the FBI.

Authorities have also used drones and infared equipment to search the family home, but have discovered no helpful clues, according to WPLG.

Teams remained at the resident on Tuesday and are continuing to process the crime scene.

Investigators have also been interviewing Jayme's school friends and checking social media, but so far have not developed any leads.

Fitzgerald has received more than 200 tips, but pleaded with the public for more information that could lead police to Jayme.

'Often, someone in the community will have knowledge of a crime and may not realize it,' he said. 'Individuals who commit acts of violence may display changes in their behavior and individuals around that person may observe those changes.'

Jayme is described as 5ft and 100 pounds, with green eyes and blond or strawberry-blond hair.

According to the teen's Facebook age, she is a dancer, as well as a cross-country and track athlete.

Anyone with information on her whereabouts or anyone that has contact with Jayme is asked to contact the Barron County Sheriff’s Department at 715-537-3106.
