A 31-year-old woman from a quiet suburb outside Tulsa, Oklahoma, has been missing for nearly three weeks, and authorities say her last known phone call contained unsettling clues that have only deepened the mystery surrounding her disappearance.

Shianne Turner was last heard from on the evening of February 3, 2026, when she placed a brief, puzzling call to her older sister, Lauren. According to Lauren Turner, who has become one of the most vocal advocates in the search effort, the conversation lasted less than 90 seconds and left her deeply unsettled.

“She sounded scared, but she was trying to keep her voice low,” Lauren told reporters outside the Tulsa County Sheriff’s Office last week. “She said, ‘I’m okay, but I need to get out of here. Don’t tell anyone I called.’ Then the line went dead. I tried calling back immediately—straight to voicemail. That was the last time anyone heard her voice.”

Shianne’s black 2019 Honda Civic was discovered abandoned two days later on a rural stretch of Highway 75 near the Oklahoma-Kansas state line. The vehicle was unlocked, keys still in the ignition, driver’s-side window partially rolled down. Her purse, phone, and personal belongings were inside, but there were no signs of a struggle—no blood, no broken glass, no tire marks indicating a sudden stop. The only anomaly: the car’s GPS showed it had made several unexplained detours through remote county roads in the hours before it was abandoned.

Tulsa County Sheriff’s deputies, working alongside the Oklahoma State Bureau of Investigation (OSBI), have classified Shianne’s case as a missing person investigation with “suspicious circumstances.” Authorities have not ruled out foul play, abduction, or voluntary disappearance, though friends and family insist the latter is impossible.

Shianne Turner was described by those who know her as dependable, soft-spoken, and deeply family-oriented. She worked as a veterinary technician at a small animal clinic in Broken Arrow and had recently become engaged to her longtime boyfriend, Ethan Caldwell. The couple had been planning a small fall wedding and had just put a down payment on a house in Owasso. Friends say she was excited about the future and had no known history of mental health crises, substance abuse, or domestic issues.

“She was the last person anyone would expect to just vanish,” said her best friend, Kayla Monroe, who helped organize a large candlelight vigil in Tulsa last weekend. “She texted me the day before she disappeared about wedding flowers. She was happy. Really happy.”

Despite extensive searches involving K-9 units, drones, ground teams, and volunteers, no trace of Shianne has been found beyond her vehicle. Authorities have combed nearby fields, creeks, and abandoned structures, but the vast rural terrain has made the effort daunting.

On February 24, 2026, the Tulsa County Sheriff’s Office released an updated appeal for information, asking anyone who may have seen Shianne or her vehicle in the days surrounding February 3 to come forward. A $25,000 reward has been offered through Crime Stoppers for information leading to her safe return or the arrest and conviction of anyone responsible if foul play is confirmed.

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 tattoo of a paw print on her left wrist and a faint scar above her right eyebrow.

Her family has created a dedicated Facebook page, “Find Shianne Turner,” which now has more than 38,000 followers. The page features daily updates, photos of Shianne smiling at family gatherings and with her beloved rescue dogs, and pleas for tips. Hundreds of people have shared the page, turning the case into a regional and even national conversation about missing women and the urgent need for faster action in such cases.

Lauren Turner, Shianne’s sister, has become the public face of the search. She has appeared on local news stations and podcasts, urging anyone with information—even something that seems insignificant—to contact authorities. “She wouldn’t just disappear,” Lauren said in a recent interview. “She loved her life. She loved her fiancé, her dogs, her job. If she’s out there, she needs us to find her. If someone knows something, please don’t stay silent.”

Ethan Caldwell, Shianne’s fiancé, has remained largely out of the public eye but released a brief statement through the family’s spokesperson: “Shianne is the light of my life. Every day without her feels impossible. We just want her home.”

As the search enters its fourth week, investigators say they are following multiple leads but remain concerned about the passage of time. The longer someone is missing, the more difficult recovery becomes—whether the person is found safe or the case shifts to a homicide investigation.

The community has rallied in support. Volunteers have organized search parties, distributed flyers, and held prayer vigils. Local businesses have donated food, water, and supplies for search efforts. A GoFundMe page created by the family to cover reward money and search expenses has raised more than $87,000.

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