If you search Jayme Closs' name on Facebook, you'll find a series of groups devoted to her case.

The 13-year-old Barron teenager has her own subreddit. Online discussion threads center around her disappearance and the murders of her parents, James and Denise Closs.

Questions have swirled for over a month as authorities investigate a case that's upended northwestern Wisconsin. James, 56, and Denise, 46, were found shot to death in their home in October, with Jayme nowhere to be found. She's been missing ever since.

As with other high-profile cases, people across the country are coming together online to speculate and discuss what may have happened to the Closs family.

"Nobody can make sense of it," said Courtney Gill, who helps run a Facebook group on Jayme's case. "There’s so many different avenues to go down, and I guess that’s why it’s gotten so big."

Gill, a Texas resident, is behind a group called Sleuth Society. Gill has always followed true crime, she said, and the group was born out of discussions between her and others over different cases. When one case — like Jayme's — receives significant attention, they create a separate group where people can exchange theories.

Gill views the group as a "safe space" for people to share their thoughts without being judged or censored. She believes it's important to keep an open eye and an open mind, though she noted that information is treated as speculation unless it comes from law enforcement.

Moderators don't necessarily encourage the Closs' family or friends to join, Gill said. And group members must follow some rules, the most crucial being to respect each other.

"It’s not my place or my position to tell someone they’re wrong," she said.

One of the more prominent theories among people online is that Jayme has a boyfriend who was involved in killing her parents. Others believe drugs were a factor. Another theory has it that Jayme is responsible for her parents' murders. Barron County Sheriff Chris Fitzgerald has said evidence doesn't support any of those possibilities.

Another recurring point of discussion is whether sex trafficking was involved. Authorities aren't yet sure one way or the other.

Social media: The good and the bad

In general, social media can have a huge impact on police investigations, said Dave Carlson, a lieutenant with the Adams County Sheriff's Department and president of the board of the Wisconsin Association of Homicide Investigators.

He said social media's reach results in police receiving countless tips from across the country, which can be overwhelming. But that's far better than getting no information at all.

Yet, Carlson said, there are some people who submit tips to interject themselves into the case for the wrong reasons. Police are also subject to more criticism on social media from those who think they've solved a case, he said.

"A lot of them will come to conclusions and (they're) pretty obvious conclusions and we certainly have probably looked at everything like that," he said.

Fitzgerald said social media can complicate investigations, noting that authorities must look into every tip they receive. Though he appreciates efforts to aid the search for Jayme, he said some tips are too broad and don't further the case. He encouraged people to be as specific as possible.

“A tip that says she’s by a river really doesn’t help us," he said.

Still, Carlson emphasized that police don't want to discourage anyone with important information from reaching out.

"We’ll deal with the stuff that’s not true, but we really, really need to know the stuff that’s true," he said.

Crystal Corbin, from South Carolina, helps moderate a Facebook group that she describes as "victim friendly."

People are prone to discuss a case like this no matter what, she said, so the group can serve as a private outlet with broad reach. And she and her fellow moderators to their best to tamp down unsubstantiated rumors.

Jayme's case has been quieter than others, Corbin said, but administrators have submitted two tips from the group to law enforcement. They don't pretend their discussions are a substitute for police work, though.

"We definitely are not out to solve a case," Corbin said. "We’re not private investigators. We don’t encourage people to do that."
