Joseph Watkins was convicted of felony murder and other crimes in the 2000 shooting death of Isaac Dawkins. A central dispute at trial was whether cell-phone evidence placing Watkins outside the area at 7:15 p.m. left enough time for him to reach the crime scene before a 911 call at 7:19. During deliberations, a juror independently drove the route and concluded Watkins could have made it; the jury convicted the next morning. Years later, Watkins raised juror misconduct, Brady, and Napue claims in a second state habeas petition. The habeas court granted relief on multiple grounds. The Supreme Court of Georgia affirmed relief on the juror-misconduct claim, holding that the test caused actual prejudice because it supplied extra-record evidence on a central, disputed issue and affected at least the juror who performed it. The timing of the test and verdict supported that conclusion; the court did not need to find that the juror shared the result with others. Because this ground alone warranted habeas relief, the Court did not reach the remaining claims.
