The disappearance of 31-year-old Shianne Turner has entered its fourth week with no new leads, but a heartbreaking revelation from her fiancé has added a layer of unease to an already perplexing case. Ethan Caldwell, who proposed to Shianne last summer and had been planning their wedding for the fall, told investigators and close friends that his fiancée expressed growing anxiety about reconnecting with a former coworker roughly two weeks before she vanished.

According to Caldwell, Shianne mentioned the encounter during a quiet dinner at their home in Owasso, Oklahoma, on January 20, 2026. “She said she was nervous about seeing this person again,” he recalled in a recent interview with local media. “She didn’t give a lot of details—just that it was someone she worked with years ago and that they had reached out unexpectedly. She kept brushing it off, saying it was probably nothing, but I could tell it was bothering her.”

Shianne never named the former coworker or explained the nature of their past relationship. Caldwell said she changed the subject quickly and seemed reluctant to elaborate further. He now wonders whether that meeting—or the anticipation of it—played any role in the events leading to her disappearance on the night of February 3.

Shianne was last heard from during a brief, cryptic phone call to her older sister Lauren around 10:40 p.m. that evening. In the call, which lasted less than 90 seconds, Shianne spoke in a hushed, tense voice: “I’m okay, but I need to get out of here. Don’t tell anyone I called.” The line then went dead. Multiple attempts to call back went straight to voicemail. Her phone has remained off or out of service ever since.

Two days later, on February 5, Shianne’s black 2019 Honda Civic was discovered abandoned along a desolate stretch of Highway 75 near the Oklahoma-Kansas border. The vehicle was unlocked, keys in the ignition, driver’s window partially down. Her purse, cellphone, and other personal items were still inside. There were no signs of a struggle—no blood, no broken glass, no skid marks. The car’s GPS history revealed several unexplained detours on rural back roads in the hours before it was left behind, routes that did not align with her usual travel patterns.

Tulsa County Sheriff’s deputies, in coordination with the Oklahoma State Bureau of Investigation (OSBI), have classified the case as a missing person investigation with suspicious circumstances. While they have not publicly ruled out foul play, abduction, or voluntary disappearance, the circumstances—particularly the abandoned vehicle and the final phone call—have raised serious concerns among investigators and the public alike.

Shianne Turner was described by everyone who knew her as dependable, warm, and deeply devoted to her family, her fiancé, and her work. She had been employed as a veterinary technician at a small animal clinic in Broken Arrow for nearly seven years. Coworkers remember her as the person who always stayed late to comfort anxious pets and their owners, who kept homemade treats in her locker for the clinic’s dogs, and who dreamed of one day opening her own rescue shelter. She and Ethan Caldwell had recently put a down payment on a modest home in Owasso and were excitedly planning a small outdoor wedding for October 2026.

“She was the happiest I’d ever seen her,” Caldwell said. “We were talking about kids, about adopting more dogs, about building a life. None of this makes sense.”

Friends and coworkers have also recalled that in the week leading up to her disappearance, Shianne received several hang-up calls at the clinic. She had dismissed them as wrong numbers, but one colleague noted that she seemed unusually distracted afterward. Whether those calls are connected to the former coworker she mentioned to her fiancé remains unknown.

Despite exhaustive searches involving K-9 units, drones, horseback teams, and hundreds of volunteers, no trace of Shianne has been found beyond her abandoned vehicle. Authorities have combed nearby fields, creeks, wooded areas, and abandoned structures along the routes shown in her car’s GPS data. Divers have searched local waterways. Billboards with her photo have been erected along major highways in Oklahoma and southern Kansas. A $25,000 reward is being offered through Crime Stoppers for information leading to her safe return or the arrest and conviction of anyone responsible if foul play is confirmed.

The Facebook page “Find Shianne Turner,” created by her sister Lauren, now has more than 42,000 followers. Daily updates include photos of Shianne smiling at family gatherings, playing with her rescue dogs, and celebrating milestones with Ethan. The page has become a hub for tips, prayer chains, and emotional support from strangers who have been moved by the case. A GoFundMe to support the reward fund and search efforts has raised over $92,000.

Lauren Turner has emerged as the public voice of the family. In recent interviews, she has pleaded for anyone with information—even something that seems minor—to come forward. “She wouldn’t just disappear,” Lauren said. “She loved her life. She loved Ethan, her dogs, her job, her family. If she’s out there, she needs us to find her. If someone knows something, please don’t stay silent.”

Ethan Caldwell has remained largely out of the media spotlight but released a short statement through the family: “Shianne is my entire world. Every day without her feels impossible. We just want her home safe. Please, if you know anything, help us bring her back.”

Shianne is described as 5’6″, approximately 135 pounds, with long dark brown hair and hazel eyes. She was last seen wearing a gray hoodie, black leggings, and white sneakers. She has a small paw-print tattoo on her left wrist and a faint scar above her right eyebrow.

As the search enters its fourth week, investigators continue to follow every lead. They are particularly interested in speaking with the former coworker Shianne mentioned to her fiancé, as well as anyone who may have seen her vehicle or had contact with her in the days leading up to February 3.

The Tulsa County Sheriff’s Office has urged anyone with information to contact them at (918) 596-6600 or Crime Stoppers at 1-800-722-TIPS (8477). Anonymous tips are welcome.

For now, the last words Shianne spoke to her sister—“I need to get out of here”—continue to echo in the minds of everyone searching for answers. Somewhere, investigators hope, someone holds the key to bringing her home.
