Cheyann Klus

A beautiful young woman goes missing, and two weeks later, her phone is used to call 911 from the middle of a forest preserve – but the caller hangs up without speaking to the operator.


Cheyann Klus has been missing from Downers Grover, Illinois since November 29, 2017. She wasn’t reported missing until December 1, but her last phone activity was November 29. Her last contact came from a desperate slew of text messages and phone calls to her best friend Chad, begging him to come pick her up from her friend/lover Brian Biddle’s house. By the time Chad saw the messages, it was too late. No one ever heard from Cheyann again.

The call made from Cheyann’s cell phone was traced to the Mallard Lake Forest Preserve, about a 20 minute drive from Cheyann’s home and the home of Brian Biddle.

Most people in Cheyann’s life believe, or did believe, that Brian Biddle had something to do with her disappearance. However, authorities say that Biddle has been cooperative and instrumental in their investigation into her disappearance. If the investigators do believe Biddle is involved in the disappearance, they don’t have enough evidence to make an arrest. Biddle is currently in Cook County Jail for charges unrelated to Cheyann’s disappearance.

There are a few theories created by those who have been following this case from the beginning. First, did Cheyann leave on her own free will because she was depressed? Cheyann’s mother and dog passed away not long before her disappearance. According to her best friend Chad, she wasn’t the same happy-go-lucky girl after the loss of her mother. This theory implies that Cheyann disappeared to commit suicide, but it leaves a lot of holes. Why would Cheyann have called Chad to come get her if she was planning on running away? Also, why would a 911 call be made two weeks after the last time she was seen if she was going to disappear on purpose?

The second theory implies that Cheyann was taken away by force, and centers around who made that call from the Mallard Lake Forest Preserve. Did Cheyann make that call, but her captor ended the call before she could speak? Or, did the captor call from that location to throw off police and the search teams on her real location? After that 911 call, a large search party was organized to try to find Cheyann (or sadly, her body) inside the preserve. Bloodhounds were brought out to trace Cheyann’s scent to no avail.

The third major theory circles around who she ended up getting a ride from the night she tried to get a hold of Chad. She made the calls to Chad from Biddle’s house, but Biddle claims he woke up and she was not there anymore. He claims to have slept for 18 hours straight. This made a lot of people suspicious online, but unfortunately, it may be true if he was coming down from a strong drug like heroin or meth. If Cheyann wanted to desperately get out there, and couldn’t wake up Brian, she may have accepted a ride from someone else she knew that was at the party. Cheyann surrounded herself with drugs and drug abusers, and was arrested with a person who has multiple drug charges just over a month before she went missing.

This arrest and her friend group should not deter anyone from urgently looking for Cheyann. Those close to her do not believe that she disappeared on her own free will. They know that she would have contacted some of her friends or family if she could. She was not a flight risk at the time of her disappearance.

The investigation seems to have gone stagnant. With no new leads, the public has mostly given up hope of finding her alive. Her family still believes she may be out there and hasn’t stopped the efforts to bring her home. They are still actively working with police investigators and their own private investigator.
