Through Supreme Court of the United States, Mental disorder and Trial

Background

During the early hours of November 20, 1987, David Riggins went to the Nevada apartment of Paul Wade, who was later found stabbed to death with wounds to the head, chest, and back. Approximately two days later, Riggins was arrested for the capital murder and robbery of Wade. After his arrest he complained of hearing voices and sleeplessness, telling the jail psychiatrist that he had taken Mellaril in the past. The psychiatrist prescribed him increasing doses of Mellaril at Riggins' request, until Riggins was taking 800 milligrams a day, considered a very high dose of that medication. Riggins was also prescribed Dilantin, which further inhibited his capabilities to appear in trial. Despite remarks doubting this dosage, it was assumed that the judgment was medically sound and accurate to Riggins' condition, as described by his psychiatrist, Dr. R. Edward Quass.

Riggins was evaluated and found competent to stand trial, with one of the three evaluating psychiatrists dissenting. Riggins stated he planned to present an insanity defense and requested that the Mellaril be discontinued until after the trial so that the jury would see his mental state first hand rather than be given a false impression induced by the medication, which would deny him due process. Riggins did not intend to be made unfit for trial. The court heard testimony from three psychiatrists with differing opinions and then gave a one-page decision denying Riggins' request. Justice O'Connor is quoted saying that she believed Riggins had to be required to continue the medication for the safety of both himself and the court.

At trial, Riggins presented an insanity defense and testified on his own behalf. He indicated that, on the night of Wade's death, he used cocaine before going to Wade's apartment. Riggins admitted fighting with Wade, but claimed that Wade was trying to kill him and that voices in his head said that killing Wade would be justifiable homicide. A jury found Riggins guilty of murder with use of a deadly weapon and robbery with use of a deadly weapon. After a penalty hearing, the same jury sentenced him to death.

Throughout the trial, Riggins had insisted upon participation in the trial without the medication he was administered, but the courts told him he had to take the medication in order to appear. Riggins argued that this was infringing upon his due process and that he was not in the proper mental state to appear while he was under the effects of the medication.

Appeals

Riggins appealed to the Nevada Supreme Court on the grounds that forced administration of Mellaril denied him the ability to assist in his own defense and gave a false impression of his attitude, appearance, and demeanor at trial. Riggins claimed that the forced medication was not justified, as the State had not demonstrated a need to administer Mellaril nor did it explore less restrictive alternatives to giving him 800 milligrams of the drug each day. Riggins also claimed that the court's forcing of his medication was an instance of prejudice, which the courts determined was not the case. However, the Nevada Supreme Court affirmed Riggins' convictions and death sentence. Riggins then petitioned the U.S. Supreme Court.
