A team searching the basement of a Mississippi courthouse for evidence about the lynching of Black teenager Emmett Till has found the unserved warrant charging a white woman in his 1955 kidnapping, and relatives of the victim who initiated the hunt want authorities to finally arrest her nearly 70 years later.

A warrant for the arrest of Carolyn Bryant Donham — identified as “Mrs. Roy Bryant” on the document — was discovered last week inside a file folder that had been placed in a box, Leflore County Circuit Clerk Elmus Stockstill told The Associated Press on Wednesday.

Documents are kept inside boxes by decade, he said, but there was nothing else to indicate where the warrant, dated Aug. 29, 1955, might have been.
