Can defendants claim self-defense while committing forcible felonies in Utah? State v. Alzaga Explained

2015 UT App 133
No. 20120742-CA
May 29, 2015
Affirmed

Summary

Cristian Alzaga was convicted of murder, aggravated assault, and aggravated robbery in connection with a drug deal gone wrong. Alzaga claimed self-defense, arguing he was attacked during a heroin transaction, while the State maintained the victims were selling marijuana when Alzaga robbed and killed them.

Analysis

The Utah Court of Appeals addressed multiple evidentiary and instructional challenges in State v. Alzaga, but the most significant holding concerned the intersection of self-defense and felony commission. This case provides important guidance on when defendants can and cannot invoke self-defense under Utah law.

Background and Facts

The case arose from a fatal encounter during a drug transaction near the Jordan River Parkway. Hannah and Mark, who lived together and sold marijuana, met with customers at a footbridge. During the transaction, Alzaga appeared with what turned out to be a toy gun, demanded their property, and ultimately stabbed both victims. Hannah died from a stab wound to the abdomen, while Mark survived with an eye injury. Alzaga claimed he was present to sell heroin and acted in self-defense when Mark attacked him.

Key Legal Issues

Alzaga raised multiple challenges on appeal, including evidentiary rulings regarding character evidence, prior convictions, and crime scene photographs. However, the most significant issue involved jury instructions on self-defense. The trial court instructed that a person cannot use defensive force when “attempting to commit, committing, or fleeing after the commission of a felony.”

Court’s Analysis and Holding

The Court of Appeals affirmed the convictions, holding that any instructional error was harmless because Alzaga was convicted of aggravated robbery, which qualifies as a forcible felony under Utah Code section 76-2-402(4)(a). Under Utah Code section 76-2-402(2)(a)(ii), a person “is not justified” in using defensive force while “attempting to commit, committing, or fleeing after the commission or attempted commission of a felony.” The court explained that because Alzaga committed aggravated robbery—a forcible felony—he could not invoke self-defense regardless of any instructional errors.

Practice Implications

This decision clarifies that defendants cannot successfully claim self-defense while committing felonies, particularly forcible felonies like aggravated robbery. The ruling also demonstrates the importance of preservation in appellate practice, as the court applied plain error review to several unpreserved claims. For practitioners, the case underscores that strategic decisions about defense theories must account for the statutory limitations on self-defense claims when felony charges are involved.

Standard of Review
