Police from a small town in Wisconsin say a teenager who was reported missing on Monday could be in danger.
Jayme Closs, 13, from Barron, Wisconsin has not been seen since the afternoon of Sunday, October 14.
On Monday, police found both her parents dead in their home after responding to a 911 call.
Investigators from the Barron County Sheriff's Department revealed James Closs, 56, and Denise Closs, 46, were killed by gunshot wounds.
A "Violent Crime Scene"
Sheriff Chris Fitzgerald described the home as a "violent crime scene," and said he believes Jayme "was in the house when this took place," but is not considered a suspect.
Instead, investigators say Closs is missing and "endangered," but have not revealed if she is considered a kidnapping suspect.
Police say a 911 call from the Closs home brought them to the crime scene Monday morning, but that no one spoke to the dispatcher during the call.
The area surrounding the home has since been searched using drones and thermal cameras, as investigators interview Closs' close friends and family.
An Amber Alert was also issued for Closs on Monday, but with no information on any persons or vehicles of interest.
The FBI and the National Center for Missing & Exploited Children are also assisting the local sheriff's department.
"At the end of the day, I want a 13-year-old here safe and sound."
In a press conference, Fitzgerald described the missing teen as sweet and shy, and said she liked sports. He also revealed Closs is not considered a runaway.
"At the end of the day, I want a 13-year-old here safe and sound - that's our goal," he told local news station WQOW.
Fitzgerald has also addressed the surprising lack of information about Closs' disappearance, and the deaths of her parents.
"That's the confusing part about this case is we don't have any leads at this time on what really took place at that house," he told People.
"There's no immediate danger that we know of, but we have a lot of unknowns in this case and that's the frustrating part."
There was one possible sighting of Closs Monday night, when she may have been seen at a Miami gas station.
Miami police have shared information from the sighting on Twitter, but the Barron County Sheriff's Department has not confirmed that the teenager seen was Closs.
The distance from Barron to Miami is reportedly 1,700 miles, or "a day's drive (nonstop)."
Closs is described as a 13-year-old girl, 5'10" tall, weighing 100 pounds, with green eyes and blond or strawberry blond hair.
