(NewsNation) — Authorities in Cambridge, Maryland, announced a man has been charged with kidnapping in the case of a missing woman who has not been seen in more than a week.

Tiyavauna Britt was reported missing to the police Feb. 13 and still has not been located. She is considered “critically missing,” according to court documents.

Kenneth Stefan Bradley, 41, was charged with kidnapping. Bradley is Britt’s ex-boyfriend, and the couple had a history of domestic violence, according to Britt’s mother.

Britt’s mother and other family members reported her missing after being unable to get in touch with the 31-year-old between Jan. 31 and Feb. 13.

Her car was found in the parking lot of a Dollar Tree with her phone and wallet inside. A note was also found inside that included the phrase “no phones, no kids, just us.” It’s not clear who wrote the letter.

Authorities say Britt was last seen Feb. 7. One acquaintance said he received a phone call from Britt around 7:30 p.m. and heard a male voice who he believed started to assault Britt before the call ended.

According to court documents, police used cellphone data to track Britt’s car to Great Marsh Park, where video footage showed a man and a woman exiting a dark-colored Chevrolet Suburban. The woman’s hands appeared to be bound.

Male and female voices were heard along with loud thuds. Those who knew them identified the voices as Britt and Bradley, according to police. Later, the man was seen on the video dragging what appeared to be a small woman into the back of his vehicle and leaving.

Bradley is currently on probation for a previous assault conviction involving Britt and is being held without bond. He is expected to appear for a preliminary hearing March 12.

Anyone with information on Britt’s whereabouts should contact the Maryland State Police.
