A teenage girl in Wisconsin has been missing since Monday after police found her parents dead inside their home, authorities said.

Jayme Closs, 13, could not be located after the Barron County Sheriff's Office received a 911 call around 1 a.m. CT (2 a.m. ET) from an address in the town of Barron, about 45 miles northwest of Eau Claire.

Sheriff Chris Fitzgerald said yelling could be heard on the call, including a cry for help, but gave little other information.

When deputies arrived, they found the bodies of James Closs, 56, and wife Denise, 46, whom Sheriff Fitzgerald identified as Jayme's parents.

Fitzgerald indicated that the Closses had been shot, saying, "This was a gunshot crime scene," but he said no weapons were found nearby.

Jayme wasn't home when law enforcement arrived, and "we are considering her missing and endangered," Fitzgerald told NBC affiliate WEAU of Eau Claire.

Ed Downing Sr., who is married to Jayme's grandmother's sister, said the family is in "disbelief" over the deaths and the teen's disappearance.

“It was just unbelievable, unbelievable. How can this be happening to us? To a small community like that, you know. It’s unreal," he told NBC News in a phone interview.

Downing said he "kept in real close contact" with Jayme's mother, Denise, and described the family as "happy-go-lucky."

“They got along exceptionally good and the daughter Jayme, she’s such a bright, intelligent … always got a big smile on her face like her mother," he said. "They always seemed like everything was going great for them, and I was always happy about that.”

“We’re just praying to God they find Jayme okay,” he said, adding that “there’s no way” she ran away from home.

The Miami Police Department in Florida tweeted that Jayme may have been spotted in the city — more than 1,600 miles away — on Monday afternoon.

"If it was her, she was in a black Ford Explorer with a possible WI plate of I60WER," the department said. "If you have any information please call 911 immediately."

Meanwhile, authorities in Wisconsin said they were still searching the area near her home as well as Riverview Middle School in Barron, which she attends. Her friends were also interviewed.

She is described as 5 feet tall and 100 pounds, with green eyes and blonde or strawberry hair.

The FBI is assisting in the case, Fitzgerald said.
