BECKLEY, W.Va. (AP) — Remains believed to be that of a woman and her daughter who have not been seen in nearly 24 years were found at a southern West Virginia home on the same day that the girl’s alleged killer died while imprisoned, state police said.

Susan Carter and her daughter, Natasha “Alex” Carter, have not been seen since Aug. 8, 2000. Members of the state police and the FBI found what were believed to be their remains Monday at the home of suspect Larry Webb, West Virginia State Police Capt. Robert Maddy said in a statement.

Webb, who was in his 80s, suffered a medical episode on Monday at the Mount Olive Correctional Complex, where he was being held without bond after having been arrested earlier this month in connection with the girl’s death. Webb was pronounced dead at a hospital six hours before the remains were discovered, the statement said.
