Does Utah's 'great risk of death' aggravator require the murderous act itself to endanger others? State v. Sosa-Hurtado Explained

The Utah Supreme Court’s decision in State v. Sosa-Hurtado provides important clarification on Utah’s aggravated murder statute, specifically addressing when a defendant’s conduct satisfies the “great risk of death” aggravator under Utah Code section 76-5-202(1)(c).

Background and Facts

Sosa-Hurtado entered a smoke shop with an assault rifle, seeking revenge against Stephen Chavez following an earlier altercation. Inside the small shop, Stephen and his father Isabel were standing only feet apart behind the counter. Sosa-Hurtado first shot at Isabel, missing but injuring him with glass fragments. He then turned to Stephen, firing one shot that hit Stephen’s hand before positioning the rifle inches from Stephen’s chest and firing two fatal shots. Isabel, only feet away, felt the air displaced by the bullets.

Key Legal Issues

The central question was whether Sosa-Hurtado’s conduct satisfied the “great risk of death” aggravator—specifically, whether the defendant must create the risk through the precise murderous act itself, or whether related acts occurring within a brief timeframe could suffice. The defendant argued that only the specific shots that killed Stephen should be considered, not the earlier shot at Isabel.

Court’s Analysis and Holding

The court reaffirmed and clarified the standard established in State v. Pierre and State v. Johnson, holding that the aggravator may be satisfied if the great risk of death was created “within a brief span of time” of the murder and the acts together “formed a concatenating series of events.” The court identified three key factors: (1) temporal relationship between the murderous act and any acts endangering a third person; (2) spatial relationship between the third party, victim, and defendant; and (3) whether and to what extent the third party was actually threatened by the assailant.

Applying these factors, the court found sufficient evidence that Sosa-Hurtado shot at Isabel seconds before killing Stephen, with all parties in close proximity within the small shop, and with clear intent to harm Isabel.

Practice Implications

This decision provides practitioners with clear guidance on arguing “great risk of death” cases. The ruling establishes that courts should examine the broader circumstances surrounding the murder, not just the final lethal act. Defense attorneys should focus on temporal and spatial separation between acts, while prosecutors should emphasize the connected nature of the defendant’s conduct and the actual danger posed to third parties. The court’s emphasis on “concatenating series of events” suggests that isolated acts separated by significant time or distance will be more difficult to connect to the murder itself.
