James Roy Knox, Appellant v. the State of Texas, Appellee

Summary

The Texas Court of Criminal Appeals affirmed the capital murder conviction, rejecting the appellant's five asserted errors: the alleged speedy‑trial violation, the admission of prior drug‑use evidence, the sufficiency of the evidence, the adequacy of corroboration for accomplice testimony, and the admission of extraneous offenses at the penalty phase. The court applied the Barker v. Wingo four‑factor test, found no constitutional violation, and held the trial court did not abuse its discretion.
