For days after Jayme mysteriously vanished - and her parents were found dead in their family home in northern Wisconsin - the sheriff had remained tight-lipped on how James and Denise Closs died, saying an autopsy needed to be conducted.
He said no gun was found at the scene and that evidence from both the house and from the 911 call indicate Jayme Closs was in the family's home when her parents were killed.
So far, he added, "we have received no tips of a credible sighting" of the girl.
Barron Area School District Superintendent Diane Tremblay described Jayme as "a sweet, quiet girl who is a loyal friend and loves to dance".
Local authorities have said investigators do not believe she ran away and they don't consider her a suspect.

"I just want to bring Jayme home, that's what I want".
The tragedy unfolded about 1 a.m. Monday with a cryptic 911 call to police.
Jayme's grandfather, Robert Naiberg, told The Associated Press on Tuesday that nothing seemed amiss at a Sunday gathering, which was to celebrate the birthday of a grandson who is cousins with Jayme. The deaths of James and Denise Closs, who had suffered gunshot wounds, were ruled homicides on Wednesday, Fitzgerald said.
"If it does not come from this podium, it is not credible information", Sherriff Fitzgerald said.
The sheriff has said that investigators could hear yelling in the background during the 911 call, but that nobody conversed with dispatchers.
He didn't say how the couple died, but the Federal Bureau of Investigation office in Milwaukee said the teen was likely abducted from her home early Monday morning by an unknown person with a gun. He implored the public to share any suspicions, including any behavioral changes in people they know, no matter how small.
As hundreds of tips continue to pour in, authorities are attempting to piece together the hours leading up to the grisly discovery.

Investigators don't have any leads or suspects, but they have enlisted the help of the National Center for Missing and Exploited Children and the Federal Bureau of Investigation, which has agents who specialize in missing children cases, the sheriff said.
She is described as 5 feet tall, about 100 pounds, with green eyes and blonde-strawberry hair. The sheriff has said authorities know whose cell phone made that call, but they have not released that information.
The national center said Monday afternoon that an Amber Alert had been issued in an effort to spread the word about Jayme's disappearance. Anyone with information is asked to call the tip line at 1-855-744-3879.
