OPINION
¶ 1 Appellant Dustin Powers pled guilty to one count of leaving the scene of an accident and was convicted after a bench trial of a second count of leaving the scene of an accident arising from the same incident. He challenges the second conviction, claiming he left the scene of only one accident and could not therefore be twice convicted of the same offense. He also contends the trial court erred at sentencing by denying him a continuance and admitting improper evidence. Finding that only one offense occurred, we vacate the second conviction. But we find no abuse of discretion at sentencing. And, on the state’s cross-appeal, we find no error in the trial court’s permitting Powers to unilaterally plead guilty to only the first count.
BACKGROUND
¶ 2 We view the facts and all reasonable inferences therefrom in the light most favorable to sustaining the convictions.
State v. Riley,
¶ 3 Powers was charged with two counts of leaving the scene of an accident in violation of A.R.S. § 28-661: leaving the scene of an accident causing the pedestrian’s death and leaving the scene of an accident causing the infant’s serious physical injuries. Powers moved to dismiss the second count, arguing that he had left the scene of only one accident. The trial court denied the motion. Over the state’s objection, Powers then pled guilty to the count involving the pedestrian, and the plea was accepted. Before trial on the count involving the infant, Powers requested reconsideration of his motion to dismiss that count. The trial court again rejected the motion. After a bench trial, the court found Powers guilty of the count involving the infant and sentenced him to concurrent, presumptive prison terms of 3.5 years. This appeal followed.
DOUBLE JEOPARDY
¶ 4 Under § 28-661, a driver involved in an accident causing injury or death commits a felony by leaving the scene of the accident. The statute provides in pertinent part:
A. The driver of a vehicle involved in an accident resulting in injury to or death of a person shall:
1. Immediately stop the vehicle at the scene of the accident or as close to the accident scene as possible but shall immediately return to the accident scene.
2. Remain at the scene of the accident until the driver has fulfilled the requirements of [A.R.S.] § 28-663.
¶ 5 Powers contends there was only one accident scene, and therefore, the second count of leaving the scene of an accident was multiplicitous and barred by the prohibition against double jeopardy. Multiplicity occurs when an indictment charges a single offense in multiple counts.
State v. O'Brien,
¶ 6 Powers relies on
State v. Tinajero,
¶ 7 Relying on
State v. Hamblin,
¶ 8 Whether one or more offenses occurred here requires us to interpret § 28-661.
See generally Tinajero,
¶ 9 The plain and ordinary meanings of the terms “accident” and “scene of the accident” do not depend on the number of victims. As commonly understood, only one accident scene exists even though accidents often involve multiple victims and impacts. 1 In the absence of compelling reasons, therefore, we give these terms their plain and ordinary meaning. See Wagstaff; Leon.
¶ 10 The statute itself does not express any legislative intent to adopt a different meaning. Section 28-661 imposes an affirmative duty on a driver to remain “at the scene of the accident,” not to render aid to victims or provide them with information. 2 Although ¶ 28-661(A)(2) requires the driver to remain at the scene “until the driver has fulfilled the requirements of § 28-663,” (emphasis added), that clause only establishes when the duty to remain at the scene terminates, it does not impose a duty to fulfill the requirements. Rather, § 28-663 is the statute that imposes an affirmative duty to perform those obligations. And a failure to perform the obligations of § 28-663 is an offense in and of itself. § 28-663(B). Moreover, basing the number of violations of leaving the scene of an accident on the number of violations of § 28-663 would, in effect, increase without legislative directive the penalty for a violation of § 28-663 from a misde-' meanor to a felony in leaving-the-accident-scene cases. Compare § 28-661(B), (C) with § 28-663(B).
¶ 11 In addition, the state also claimed at oral argument that the legislature, in specifying that the severity of the injury suffered determines the class of felony committed, intended to permit multiple violations of ¶ 28-661 at a single accident. Specifically, the state notes that leaving the scene of an accident resulting in death or serious physical injury is a class four felony and leaving the scene of an accident that does not result in death or serious physical injury is a class six felony. § 28-661(B) and (C). Thus, the state argues, if a defendant leaves the scene of an accident resulting in a serious physical injury to one person and a minor injury to another, the defendant has committed a class *127 four felony as to the first person and a class six felony as to the second.
¶ 12 First, we would hesitate to expand the ordinary and commonsense meaning of terms in a criminal statute based on inferential reasoning from the penalty provisions.
See Bouie,
¶ 13 Furthermore, our interpretation of the statutory language is supported by a principal objective of § 28-661, “prohibit[ing] drivers from seeking to evade civil or criminal liability by escaping before their identity can be established.”
State v. Rodgers,
¶ 14 In addition, our conclusion is in accord with courts in other jurisdictions interpreting similar statutes.
See Dake v. State,
¶ 15 Therefore, we agree with the court in
Tinajero
that § 28-661, which refers to leaving “the scene of the accident” as a geographic offense, permits only one conviction for leaving one accident scene regardless of the number of persons injured or killed.
Tinajero,
¶ 16 Applying our interpretation of § 28-661 to the facts here, only one offense occurred. Both victims were injured in one event at one location. Therefore, Powers left only one accident scene.
Tinajero.
Because there was only one accident scene and Powers was charged with the same offense twice, the indictment was multiplieitous.
See O’Brien,
*128 SENTENCING
¶ 17 Powers contends the trial court erred by refusing to grant him a continuance to allow his mitigation witness to testify at sentencing. We review the trial court’s refusal for an abuse of discretion.
See State v. Quintana,
¶ 18 Powers requested that sentencing be continued, claiming his mitigation witness, a psychologist, had been unable to conduct a follow-up evaluation because the psychologist had been out of town due to a family illness and could not appear at sentencing. “[T]he purpose of a pre-sentence hearing is to insure that the sentencing judge is fully informed as to the character of the individual to be sentenced and the circumstances of the crime.”
State v. Ohta,
¶ 19 Powers also contends the trial court erred at sentencing in admitting “emotional testimonials and evidence regarding the deceased” from the pedestrian’s family and a friend. We need not consider whether this information was admissible because, even if it was improperly received,
4
there is no sentencing error unless the trial court was improperly influenced by it.
See State v. Mann,
¶ 20 “Absent proof to the contrary, the trial judge ... must be presumed to be able to focus on the relevant sentencing factors and to set aside the irrelevant, the inflammatory, and the emotional factors.”
State v. Beaty,
¶21 Finally, Powers argued for the first time at oral argument that we should remand for resentencing because, by vacating one of the convictions, we have “unbundled” the trial court’s “sentencing package.” The essence of this argument is that the trial court imposed concurrent, presumptive sentences because there were two convictions and that the trial court would have imposed a lesser sentence if there had been only one conviction. Arguments raised for the first time at oral argument are waived.
See State v. Rossi,
CROSS-APPEAL
¶ 22 The state cross-appeals from the trial court’s acceptance of Powers’s guilty plea to one count of leawng the scene of the accident. We find no basis to preclude Powers from unilaterally entering a guilty plea to part of the indictment. The state cites authority establishing that it has the right to decide which charges to file and whether to offer a plea agreement. 5 But those cases are inapposite because the state determined which charges to file and because the guilty plea was not made pursuant to a plea agreement. The state also contends Powers’s guilty plea to part of the indictment was a “backdoor” method of severing the charges. But the charges were not severed for trial; Powers simply pled guilty to one of the offenses. Finally, the state contends the trial court’s acceptance of Powers’s guilty plea to one count permitted him to assert a double jeopardy violation on the other. But Powers’s double jeopardy claim arises because the state issued a multiplicitous indictment, not because Powers pled guilty. 6 Moreover, because Powers pled guilty to one count of the offense and we have found the second count of the same offense barred because it was multiplicitous, the state has suffered no damage; Powers was convicted of the offense. The trial court, therefore, did not err in accepting Powers’s plea of guilty to part of the indictment.
CONCLUSION
¶ 23 Powers’s conviction and the sentence imposed on count one of leaving the scene of an accident is affirmed. Powers’s conviction and the sentence imposed on count two of leaving the scene of an accident is vacated.
Notes
. Although it is not entirely clear from the record presented to us that Powers's vehicle actually struck the stroller, we view the evidence and reasonable inferences therefrom in the light most favorable to sustaining the conviction.
Riley,
. In contrast, offenses that permit a single act to result in multiple counts focus directly on the effects of a defendant’s act on another person.
See, e.g., State v. Henley,
. Adopting this interpretation does not require that we disagree entirely with Hamblin. If a defendant pleads guilty to having left multiple accident scenes or if a trier-of-fact properly finds that a defendant has done so, a defendant can be found guilty of multiple violations of the statute.
. The state did not argue that members of the pedestrian’s family were victims.
But see
Ariz. Const. art. II, § 2.1(A)(4) and (C); A.R.S. §§ 13-4401(6) and (18) and 13-4426(A);
State ex rel. Romley v. Superior Court,
.
State v. Hankins,
. Had Powers pled guilty to a lesser-included offense that was part of the indictment, double jeopardy would not have attached to bar prosecution of the greater offense.
