The family of an Oklahoma teen missing since October pleaded with the public Thursday for information on her whereabouts.

Faith Lindsey, 17, of Pauls Valley was last heard from Oct. 29. She was reported missing Nov. 4.

The Oklahoma State Bureau of Investigation offered a $5,000 reward on Nov. 27 for any information leading to her discovery. Her family has pleaded for information leading to her safe return.

“We miss her terribly,” Lindsey’s grandmother, Mary Tucker, told Oklahoma City ABC-affiliate, KOCO. “Call the OSBI. They will check out any leads.”

Her boyfriend, with whom she reportedly lived, expressed his concern after he was unable to contact her.

“He texted me Monday night saying that he can't find her; she's missing, freaking out,” her sister, Justice Lindsey, told reporters. “She's always contacted me. She knows my number by heart.”

Justice Lindsey said she received strange texts from her sister’s phone.

“She was misspelling a lot of things that night, and Faith, she has very good punctuation and spelling and that just wasn't her,” she continued. “She kept trying to call me a lot, but hung up as soon as I answered, which is kind of suspicious.”

“"I have a gut feeling something did happen to her. I really hope that she's safe.”

Investigators searching for Lindsey have expanded the territory from Pauls Valley to nearby Seminole, Garvin and Pontotoc counties.

“Everything's on the table, but at this point in time we are actively looking for Faith in hopes that she is safe and sound,” OSBI spokeswoman Brook Arbeitman told reporters.
