2019 UT App 193

THE UTAH COURT OF APPEALS

STATE OF UTAH, Appellee, v. SETH GORDON PETERSON, Appellant.

Opinion No. 20180369-CA Filed November 29, 2019

Seventh District Court, Price Department The Honorable George M. Harmond No. 161700479

Robert A. Oliver, Attorney for Appellant Sean D. Reyes and Lindsey L. Wheeler, Attorneys for Appellee

JUDGE KATE APPLEBY authored this Opinion, in which JUDGES MICHELE M. CHRISTIANSEN FORSTER and JILL M. POHLMAN concurred.

APPLEBY, Judge:

¶1 Seth Gordon Peterson killed his mother (Mother) and brother (Brother) and appeals his conviction for the aggravated murder of Brother. Peterson presented a voluntary intoxication defense at trial claiming he did not intentionally kill Mother or Brother because he had experienced psychosis from methamphetamine use and therefore could be convicted only of manslaughter for each killing. He contends the jury accepted this defense as to Mother but not Brother and therefore reached an inconsistent verdict. We affirm. State v. Peterson

BACKGROUND

¶2 Peterson lived on a farm in central Utah with his two uncles. They used methamphetamine together “religiously every day.” Peterson denied using methamphetamine the day of the killings, but later claimed he did and suffered from methamphetamine psychosis.

¶3 The day before the homicides, Peterson and one of his uncles (Uncle C) drove to Salt Lake City, Utah to purchase drugs. During the drive Uncle C said Peterson told him “an entity . . . offered [Peterson] mortality on this earth if [he] were to offer up one of [his] brothers’ limbs or lives” and that Brother was “a leader of all demons.” Uncle C asked Peterson if he told the entity “no,” but Peterson did not respond. The next morning on their way home, Peterson told Uncle C he did not want to use drugs anymore and asked for help.

¶4 Once they arrived home, Peterson was “clearly disturbed” and “very upset.” He told his other uncle (Uncle J) that he would kill Brother that day. Peterson then told Uncle J about the “entity” who told him “he would receive the ultimate power” if he killed Brother.

¶5 Later that day, Peterson called 911. He told the dispatcher that he felt like his “life [was] in danger” and that he needed help immediately. The dispatcher asked if anyone had a weapon or had taken any drugs, and Peterson told her there were weapons. When asked whether the weapon was a gun, Peterson refused to answer any additional questions. The dispatcher told Peterson she needed to make sure the responding officers were safe, and he told her that “they may not be.” He insisted he needed assistance but never told the dispatcher what was wrong. In the background of the call, Peterson can be heard telling Uncle J he called the police because he did not feel safe and he was scared for his life. Uncle J told Peterson he was

acting “insane,” and in response, Peterson attempted to “cancel” the 911 call because everything was “alright.” The dispatcher told Peterson she could not cancel the call. Peterson hung up on her.

¶6 Police officers responded to the residence and Uncle J informed them that Peterson intended to “kill [Brother] that day.” An officer spoke with Peterson, who was showing signs of “obvious paranoia” but not intoxication. The officer reported that Peterson came “back to reality quite a few times and he was calm” and overall was “very nice” and “cordial.” The officer repeatedly asked Peterson if he had been using methamphetamine, and Peterson denied doing so. The officers unloaded all the guns on the property, including Peterson’s and Uncle C’s rifles. They contacted Mother, and she agreed to come over to look after Peterson. The officers left the house and Mother and Brother arrived about forty minutes later.

¶7 When Mother and Brother arrived, Peterson greeted them as if “everything was normal.” Soon after they arrived, Uncle C decided to go look for a wounded deer he saw on the farm. Mother and Peterson went with him, while Brother and Uncle J remained at the house. Peterson watched Uncle C load his rifle and then got his own rifle.

¶8 Uncle C, Mother, and Peterson left on an all-terrain vehicle to go look for the deer. They drove to a field and separated to look for it. Uncle C went one way while Mother and Peterson went another. Uncle C overheard the other two briefly argue. Mother tried to take Peterson’s rifle, but he pushed her away. Next, Uncle C heard Peterson yell, “[N]o you’re not” followed by the sound of a gunshot and a “horrifying scream.” Uncle C saw Mother running down the hill with her face “all red.” He heard Mother “making a noise . . . like her larynx had gotten blown out.” She “squeal[ed] . . . like a pig”

and Peterson made a similar noise while “laughing” and “mocking” her.

¶9 Uncle C approached Mother and noticed her “face was . . . gone.” He yelled to Peterson, “[W]hat did you do to your mom?” to which Peterson responded, “I shot her in the fucking face.” Next, Uncle C saw Brother driving toward them, but his truck got stuck in a ditch near Mother. Peterson reloaded his rifle and shot Mother in the back. Peterson then approached Brother, who was sitting in the truck, and shot him in the face. Peterson pulled Brother’s body from the truck and drove the truck out of the ditch. He returned to Brother’s body, rifled through Brother’s pockets, took twenty dollars, and left the body in the ditch. Peterson then fled in the truck.

¶10 Peterson returned to the house and encountered the owner (Owner) of the farm. Peterson calmly explained that he needed help burying “two bodies” and that he “just killed two demons.” Owner told Peterson he would help if Peterson gave him his gun. Owner’s cellphone rang, startling Peterson, who pointed his rifle at Owner’s chest and “motion[ed] towards the trigger.” Owner grabbed the rifle and hit Peterson with it. Peterson ran to Owner’s truck and retrieved a crowbar. Owner called 911 and put the phone in his pocket as Peterson lunged at him with the crowbar. Peterson struck Owner with the crowbar “eight to fifteen times,” and Owner thought Peterson was “trying to kill” him. Peterson eventually “got tired” and drove off.

¶11 The first officers to arrive at the scene saw Peterson driving erratically down the street. The officers tried to pull Peterson over, but he kept driving, which triggered a high-speed chase. Peterson was driving “very fast,” weaving in and out of lanes. He threw glassware, a backpack, and a duffel bag out the truck window. Eventually he veered off the road and crashed.

He ran up a hill, but was pursued by officers who caught and arrested him.

¶12 Shortly after his arrest, Peterson admitted he “killed [his] family.” He was transported to a hospital where he claimed he used methamphetamine that day. 1 He was later released from the hospital and booked into jail.

¶13 Peterson spoke to several family members the next day. They believed Peterson’s drug use caused him to kill Mother and Brother. One of his brothers told him “[R]emember in your legal defense, that, you know, you had no clue, like you honestly thought [Mother and Brother] were the devil . . . because you can claim insanity, not that you are insane right now, but when you were on drugs . . . it does that to you sometimes.”

¶14 The next day, a detective (Detective) interviewed Peterson. Peterson told Detective he had been using methamphetamine prior to and on the day of the homicides. He said he had not slept for four days before the homicides. Peterson explained that while he was buying drugs in Salt Lake City he began experiencing hallucinations and felt he was being followed.
