The defendant was convicted of first-degree murder. The case was appealed and the appellate court reversed. Of importance, the Tuttle cases made state law regarding the use and unreliability of hypnotically enhanced testimony at trial. State v. Stettina 868 P.2d 108 (Utah App. 1994) The defendant was convicted of kidnapping and forcible sexual abuse. This case importantly delineated the Utah rule that consecutive sentences may not be aggregated to exceed 30 years and the exceptions to it. State v. Vigil 842 P.2d 843 (Utah 1992) The defendant was charged with various counts of murder and attempted murder. This case ultimately redefined what is required under Utah law to convict a person for "attempted" murder. As the Supreme Court reversed the conviction, it found there could be no crime of attempted "depraved indifference" murder.

The defendant was convicted of first-degree murder following a jury trial. The case was appealed and reversed, resulting in a new trial. On retrial, the defendant was convicted of the lesser charge of manslaughter. The case was appealed again, and state law was made regarding the use and unreliability of post-hypnotic testimony at trial. Ultimately, the Utah Supreme Court agreed that hypnotically enhanced testimony is inherently unreliable and inadmissible as evidence and that the admission of hypnotically enhanced testimony required reversal.
