MABSCOTT, W.Va. (WCHS) — Investigators may be a step closer to solving a decades old case in Raleigh County involving a missing mother and her daughter.

The Federal Bureau of Investigation in Pittsburgh confirmed it conducted "law enforcement activity" at a home on Kyle Road in Mabscott on Tuesday in connection to the investigation into the 2000 disappearance of Susan Carter and daughter, Natasha "Alex" Carter.

Troopers said they were able to identify and recover additional forensic evidence related to the investigation.

Age-progressed photos of Natasha "Alex" Carter were previously provided by the National Center for Missing and Exploited Children in 2021, when the FBI announced it was offering a $10,000 reward for information in the case. (National Center for Missing and Exploited Children)

"We, along with our law enforcement partners, are working diligently to bring answers to Alex Carter’s family," FBI spokesperson Catherin Coennen said.

Natasha, 10, and Susan, 40, were last seen in the Beckley area on or about Aug. 8, 2000, according to investigators. At the time of their disappearance, Susan and Natasha’s father were having a custody dispute and the girl had moved in with her mother and her mother’s new husband. Not long after she moved in, the pair vanished.
