A 24-year-old Oklahoma man has been arrested on a first-degree murder warrant in the suspected death of his 17-year-old girlfriend, authorities said Friday.

Tanner Washington of Stratford was arrested Thursday night in the suspected death of Faith Lindsey, who has not been seen since Oct. 29, said Oklahoma State Bureau of Investigation spokeswoman Brooke Arbeitman.

Washington is being held in the Oklahoma County jail on the murder warrant from Pontotoc County. Court records didn't list an attorney who could speak on his behalf.

Arbeitman said she could not comment on why the OSBI believes Lindsey is dead because the investigation is ongoing.

Arbeitman said Lindsey was reported missing by her sister to police in Paul's Valley, where Lindsey lived.

The OSBI is offering a $5,000 reward for information leading to Lindsey or her remains.
