DOTHAN, Ala. — Kharon Davis spent a decade in jail awaiting trial. On Friday, a jury in this southern Alabama town deliberated less than three hours before finding him guilty in the fatal shooting of Peter Dwayne Reaves.

Mr. Davis’s case had attracted national attention because of the extreme length of his incarceration while he was still presumed innocent. His trial was delayed multiple times because of misplaced evidence, conflicts of interest and his own dissatisfaction with successive teams of lawyers.

Mr. Davis, 33, is black, but the jury was all white, in a county with a long history of striking blacks from juries. Jury selection took place on Monday and Tuesday, and Mr. Davis’s lawyers complained to the judge about the racial makeup of the jury, unsuccessfully arguing that a new pool be assembled.

Mr. Davis was one of three men charged in Mr. Reaves’s death. One of the others, Lorenzo Stacey, was acquitted. The third, Kevin Bernard McCloud, took a plea bargain in which he agreed to plead guilty and testify against Mr. Davis, a childhood friend, if prosecutors did not seek the death penalty. He is serving a 99-year sentence.
