The FBI is asking for America’s help in locating a 13-year-old girl that’s been missing since her parents were found dead on Monday. Jayme Closs was believed to be in her family’s home in Wisconsin when her parents were killed, and has not been seen since.

At around 1 a.m. on Monday, Wisconsin’s Barron County Sheriff’s Department received a 911 call from a cell phone believed to be inside the home of Jayme Closs. Few specific details have been released regarding the call, but there was no one interacting with the dispatcher on the line. Instead, the noises that could be heard in the background prompted the Sheriff’s Department to dispatch a car to investigate. When law enforcement arrived on the scene, they found James and Denise Closs shot to death inside the house, with no sign of Jayme anywhere.

Jayme Closs was first reported missing at 8 a.m. on Monday, but a nationwide Amber Alert wasn’t released until later in the afternoon as law enforcement gathered pertinent information about the girl. Since then, no leads have surfaced regarding her whereabouts, and federal law enforcement has joined with local authorities in asking the American public to keep an eye out for the missing child.

“We believe Jayme was in the home at the time of the homicides and we believe she’s still in danger,” Barron County Sheriff Chris Fitzgerald said Wednesday.

He added, however, that he has a “100 percent expectation that she’s alive.”

Jayme Closs is described as approximately 5 feet tall, weighing about 100 pounds, with green eyes and strawberry blond hair. She was last seen in Barron, Wisconsin on Monday, but could potentially be anywhere in the nation by now. Authorities have stated that they don’t believe the girl ran away, nor is she considered a suspect in the homicide investigation. Further details have been scarce at times, which Sheriff Fitzgerald has indicated is by design.

“Our number one goal is to bring Jayme home, and no amount of information will be given out unless we feel it’s appropriate to help,” he told the press.
