Police report that 13-year-old Keyanna Sylvester, an Alabama teen who was reported missing last week and then located in Mississippi on Sunday, has died in the hospital.

Sylvester reportedly ran away from her home in Mobile on March 21, and was seen two days later in Moss Point.

Soon after, police say the girl was located at a motel in D’Iberville and taken to a local hospital.

D’Iberville Police Capt. Jason King said that Sylvester was found unresponsive.

Sylvester had no identification on her when she was found and was first listed as Jane Doe. She was positively identified on Sunday.

Police say the circumstances around Sylvester’s death are unclear.

Officials are currently awaiting on a report from the medical examiner to determine if there was any foul play involved.
