State of Arizona v. Edwardo Serrato III, 568 P.3d 756

Background

Edwardo Serrato III was convicted of several crimes, including arson of an "occupied structure," after setting fire to a truck in Kingman, Arizona, linked to a broader criminal episode involving a homicide and attempted arson of a house.
The trial court imposed consecutive sentences totaling 135 years, with 35 years related to the arson conviction of the vehicle.
On appeal, the prosecutor argued that Serrato’s own presence at the scene made the vehicle an "occupied structure" under Arizona law.
The court of appeals affirmed the arson conviction, holding that the defendant's presence alone satisfied the occupancy requirement of A.R.S. § 13-1704.
The Arizona Supreme Court granted review to resolve, as an issue of first impression, whether an arsonist’s own presence can constitute occupancy of a structure under Arizona’s statutory scheme.
The Supreme Court reversed the arson conviction for the "occupied structure" count and remanded, clarifying the statutory interpretation.

Issues

Issue	Serrato’s Argument	State’s Argument	Held
Does the arsonist’s own presence make a structure “occupied” under A.R.S. § 13-1704?	Only a human being other than the arsonist can satisfy the occupancy requirement; otherwise, the statute is rendered meaningless.	“Human being” includes any person, so the arsonist’s presence alone suffices; this interpretation aligns with public safety aims.	No; the court held that the statute’s context excludes the arsonist from the term “human being” for the purpose of occupancy.
Should the arson statutes be interpreted literally or contextually?	Statutes should be read in context to avoid making other provisions (e.g., arson of a structure) superfluous.	Literal reading is correct, and helps protect all lives present, including offenders.	Statutes must be interpreted contextually to give effect to each provision and preserve the tiered penalty scheme.
Does the legislative history indicate who qualifies as a "human being" under the statute?	Legislative history is ambiguous and should not override clear statutory text and context.	Amendments dropping specific exclusions imply broader inclusion, covering the arsonist.	Legislative history is, at most, ambiguous; court relies on unambiguous contextual reading.
Should the rule of lenity apply?	If ambiguity exists, the statute should be interpreted in Serrato’s favor.	No ambiguity in statute, so lenity does not apply.	Rule of lenity is inapplicable because the statute is unambiguous in context.
