Texas death penalty scheme was originally found constitutional by the Supreme Court in Jurek v. Texas, 428 U.S. 262, 270-72, 96 S. Ct. 2950, 2956, 49 L. Ed. 2d 929 (1976), and has not been changed substantially since then. Further, capital punishment does not violate the United States or Texas Constitutions. Lawton v. State, 913 S.W.2d 542 (Tex.Cr.App. 1995), cert. denied, 519 U.S. 826, 117 S. Ct. 88, 136 L. Ed. 2d 44 (1996). The Texas death penalty statute provides proportionality and does not violate the Fifth, Sixth, Eighth or Fourteenth Amendments. Graham v. Collins, 950 F.2d 1009 (5th Cir. 1992), cert. granted, 504 U.S. 972, 112 S. Ct. 2937, 119 L. Ed. 2d 563, (1992), aff'd, 506 U.S. 461, 113 S. Ct. 892, 122 L. Ed. 2d 260 (1993), reh'g denied, 507 U.S. 968, 113 S. Ct. 1406, 122 L. Ed. 2d 778 (1993). Also, the death penalty statute is facially constitutional. Lane v. State, 822 S.W.2d 35 (Tex.Cr.App. 1991), cert. denied, 504 U.S. 920, 112 S. Ct. 1968, 118 L. Ed. 2d 568 (1992). Moreover, the Texas capital murder-sentencing scheme, which provides a mandatory life sentence for capital murder, is not cruel and unusual punishment. Cantu v. State, 939 S.W.2d 627 (Tex.Cr.App. 1997), cert. denied, 522 U.S. 994, 118 S. Ct. 557, 139 L. Ed. 2d 399 (1997).
