Arizona v. Youngblood

Chief Justice Rehnquist delivered the opinion of the Court.

Respondent Larry Youngblood was convicted by a Pima County, Arizona, jury of child molestation, sexual assault, and kidnaping. The Arizona Court of Appeals reversed his conviction on the ground that the State had failed to preserve semen samples from the victim’s body and clothing. 153 Ariz. 50, 734 P. 2d 592 (1986). We granted certiorari to consider the extent to which the Due Process Clause of the Fourteenth Amendment requires the State to preserve evidentiary material that might be useful to a criminal defendant.

On October 29, 1983, David L., a 10-year-old boy, attended a church service with his mother. After he left the service at about 9:30 p.m., the boy went to a carnival behind the church, where he was abducted by a middle-aged man of medium height and weight. The assailant drove the boy to a secluded area near a ravine and molested him. He then took the boy to an unidentified, sparsely furnished house where he sodomized the boy four times.. Afterwards, the assailant tied the boy up while he went outside to start his car. Once the assailant started the car, albeit with some difficulty, he returned to the house and again sodomized the boy. The assailant then sent the boy to the bathroom to wash up before he returned him to the carnival. He threatened to kill the boy if he told anyone about the attack. The entire ordeal lasted about YA hours.
