As police become more and more desperate to find missing 13-year-old Jayme Closs, they are revealing more information to the public. On Oct. 17, Barron County, WI, Sheriff, Chris Fitzgerald, announced that his team is confident that Jayme was in the house when her parents were murdered.

“We believe Jayme was in the home at the time of the homicides and we believe she’s still in danger,” he said, three days after the horrific crimes, according to ABC Action News. While there has so far been no trace of Jayme found anywhere, he still think she hasn’t been killed. “[There’s a] 100 percent expectation that she’s alive,” at this point, said the sheriff.

An Amber Alert was issued for Jayme on Monday, Oct. 15, but while hundreds of good Samaritans have sent in tips, none have lead to Jayme’s whereabouts, a potential killer, or a motive for why someone would want to kill James Closs, 56, and Denise Closs, 46.

Right now, the best info authorities have is coming from the 911 tapes. Though no one ever spoke directly to the dispatcher during the attack, someone in the house dialed the number, and four minutes later police were at the home. Unfortunately it was too late. Now the FBI is looking at the tapes, which have places Jayme in the home at the time. They also know whose cell phone the call came from, though so far they haven’t revealed that information. No vehicles were at the home when the police got there, and police have been able to confirm that Jayme didn’t just flee into the woods.

Jayme Closs is 5 feet tall, weighs 100 pounds and has green eyes and blond or strawberry blond hair, the sheriff’s department said. Anyone with information can call the tip line at 1-855-744-3879. Our thoughts are with friends and family of the Closses at this horrible time.
