OPINION
{1} In this direct appeal from Defendant’s conviction of felony murder, attempted armed robbery, and several other crimes, Defendant presents certain double jeopardy arguments, challenging his attempted armed robbery conviction as being the predicate for his felony murder conviction. In the course of addressing those arguments, we decide, for the first time, whether the single-larceny doctrine applies to the crime of attempted armed robbery. Addressing that issue and others regarding double jeopardy, as well as Defendant’s claim of ineffective assistance of counsel, we affirm Defendant’s convictions.
BACKGROUND
{2} In the early morning of September 3, 2000, two masked gunmen broke into Felipe Giron’s house in Belen, intent on robbing him. The gunmen had apparently learned that Giron had nearly $10,000 in cash at his home, purportedly the proceeds of illegal drug sales. They entered Giron’s bedroom where he and Giron’s live-in girlfriend, Carey Romero, were sleeping. Almost immediately, one of the men shot Giron in the head with a rifle, killing him.
{3} The men then pointed their guns at Romero and demanded she produce the money. Initially, Romero huddled under the covers of the bed for safety. The gunmen forced her out of bed, poked her with their weapons, and demanded that she find the money. At gunpoint, Romero was forced to look through the drawers in the bedroom, but did not find any money. She then turned on the lights in the house and proceeded through the living room to the dining room. During the entire time, one of the gunmen followed her closely with a gun. The gunmen continually yelled at her to hurry and threatened to kill her. She looked through a desk in the dining room, and then started searching a closet. She could not reach the top shelf of the closet, so the gunmen both attempted to reach the shelf. This distracted the gunmen enough to allow Romero to escape through the front door of the house and flee to a neighbor’s house, where she called police. The two men left the house without finding any money.
{4} Romero was not able to identify the gunmen and no immediate arrests were made. Over two years later, Erie Jaramillo, a former gang member, was arrested on an unrelated charge of armed robbery. He told police that he knew who killed Giron. In exchange for leniency on his charge, Jaramillo testified that Defendant had confessed to the attempted robbery and murder of Giron. Based upon Jaramillo’s testimony, Defendant was indicted on charges of first-degree murder on the alternative theories of willful and deliberate murder, NMSA 1978, § 30-2-1(A)(1) (1994), or felony murder, Section 30-2-l(A)(2), two counts of attempted armed robbery, NMSA 1978, § 30-16-2 (1973), and various other crimes. 1 At trial, both the prosecution and defense acknowledged that Jaramillo’s testimony was the only direct evidence linking Defendant to the crime.
{5} A jury found Defendant guilty of felony murder, both counts of attempted armed robbery, and other charges. Prior to sentencing, the trial court dismissed Defendant’s conviction for the attempted armed robbery of Giron because, according to the court, that count represented the predicate felony for the felony murder conviction. The court sentenced Defendant for the attempted armed robbery of Romero. Defendant received a sentence of life imprisonment plus twenty-nine years for the murder, the attempted robbery of Romero, and the other remaining convictions. He now appeals directly to this Court from the trial court’s judgment and sentence. See Rule 12-102(A)(1) NMRA (direct appeal to Supreme Court of convictions in which sentence of life imprisonment imposed).
DISCUSSION
Double Jeopardy
{6} Defendant appeals on double jeopardy grounds asking us to reverse his conviction for the attempted armed robbery of Romero. A double jeopardy claim is a question of law that we review de novo. State v. Andazola,
{7} The Double Jeopardy Clause of the Fifth Amendment protects citizens against multiple punishments for the same offense. Swafford v. State,
{8} Defendant advances two arguments. First, he claims that his remaining conviction for the attempted armed robbery of Romero was a predicate felony for the felony murder conviction and, like the attempted robbery of Giron, was unitary with the felony murder and must be dismissed. Second, Defendant claims he committed only one continuous attempted armed robbery which involved two victims, with only one object-Giron’s money. There being only one crime, Defendant argues that since the conviction for attempted armed robbery of Giron was dismissed, the conviction for the attempted armed robbery of Romero must be dismissed as well.
{9} For his first argument, Defendant states a double-description claim because he claims that he was wrongfully convicted under two different statutes for unitary conduct: attempted armed robbery and felony murder. For double-description claims, this Court follows the two-part test identified in Swafford,
{10} Felony murder has its own particular double jeopardy analysis. If the predicate felony and felony murder are unitary, then the predicate felony must be dis-missed because it is subsumed within the elements of felony murder. State v. Contreras,
{11} The facts of this case indicate that, unlike the attempted robbery of Giron, the attempted robbery of Romero was not unitary with Giron’s murder. Most significantly, the murder of Giron was complete before the would-be robbers turned their attention to Romero and began to use force and threatened force against her. See State v. DeGraff,
{12} We turn now to Defendant’s second argument: that only one attempted robbery occurred, involving two victims. Since the trial court dismissed one attempt, Defendant argues no conduct remains to sustain a second attempted robbery count. Defendant asserts that only one continuing attempted robbery took place because the assailants moved from Giron to Romero with the single intent of stealing Giron’s money. If only one attempted robbery occurred, then there was only one predicate felony, which, as we have seen, must be dismissed as the predicate to the felony murder. However, if two attempted robberies occurred, one of Giron and one of Romero, then the conviction for the attempted robbery of Romero can stand because that robbery was not unitary with the murder of Giron.
{13} To determine whether two attempted robberies occurred, we must undertake a unit-of-prosecution analysis. For unit-of-prosecution challenges, the only basis for dismissal is proof that a suspect is charged with more counts of the same statutory crime than is statutorily authorized. Herron v. State,
{14} The unit-of-prosecution analysis is done in two steps. First, we review the statutory language for guidance on the unit of prosecution. State v. Barr,
{15} Our first opinion to frame the unit-of-prosecution indicia of distinctness under the modern analysis was Herron,
{16} The Herron unit-of-prosecution factors were cited in Swafford, a double-description case, and adopted as part of the double-description, unitary-conduct inquiry. See Swafford,
{17} Unit-of-prosecution cases after Swafford have generally emphasized the six factors from Herron or some slight variation thereof. See, e.g., DeGraff,
{18} The number of victims has been a particularly significant indicator in determining whether acts are distinct. See State v. Dominguez,
{19} We turn now to the specific statutes for attempted robbery. Section 30-16-2 (robbery); NMSA1978, § 30-28-1 (1963) (attempt). If the statutory language for attempted robbery were clear regarding the unit of prosecution, then the language would control, and the unit-of-prosecution analysis would be complete. In New Mexico, “Robbery consists of the theft of anything of value from the person of another or from the immediate control of another, by use or threatened use of force or violence.” Section 30-16-2. Therefore, the two basic elements of robbery are theft and the use or threatened use of force. Id.; UJI 14-1620 NMRA. The statute provides no guidance on the number of prosecution units regarding either the number of thefts or use of force. Attempted robbery is “an overt act in furtherance of and with intent to commit [robbery] and tending but failing to effect its commission.” Section 30-28-1. This statute likewise does not provide guidance as to the proper unit of prosecution for multiple attempts. Thus, we look to the indicia of distinctness factors to determine whether Defendant committed one or two attempted robberies.
{20} In this case, the indicia of distinctness are more than sufficient to justify convicting Defendant of two attempted robberies. Importantly, there were two victims, and most notably, each victim suffered separate and distinct harms at the hands of Defendant. As we mentioned in examining Defendant’s double-description argument, the first attempted robbery was clearly completed at the time Defendant burst into Giron’s bedroom and Giron was shot, suggesting distinct conduct. See DeGraff,
{21} As further evidence of distinct conduct, the assailants used a different type of force against Romero than against Giron— poking her with guns and threatening her with violence, as opposed to firing a weapon. Cf. Herron,
{22} Perhaps aware of these points of distinct conduct, Defendant argues that he only had one criminal intent — to rob Giron’s money — and therefore, there could be only one attempted robbery. Defendant draws an analogy to the single-larceny doctrine. See State v. Brown,
{23} This raises an issue of first impression in New Mexico. We have not previously addressed the proper unit of prosecution for robbery (or attempted robbery) when more than one victim is involved, but the defendant only intended to steal money from a single person. Accordingly, we look to other jurisdictions for guidance. We note a split on the question of whether multiple robbery convictions are allowed when force is used against multiple victims, but the assailant has the single intent to steal property held in common or belonging to only one of the victims. Facon v. State,
{24} Some jurisdictions, like Maryland, California, and Virginia, have allowed multiple charges of robbery when multiple victims are present. In a case that bears some similarity to this case, the Maryland Court of Appeals upheld multiple robbery convictions when a thief killed a husband and wife in separate acts and then took money from a wallet they kept in their house. Borchardt v. State,
{25} The California Supreme Court took a similar view when it upheld multiple robbery convictions where assailants, in the course of robbing a fast food restaurant, shot one employee and bludgeoned another. People v. Ramos,
{26} Expressing a contrary view, some jurisdictions have limited the unit of prosecution for robbery when the defendants exhibit a single intent. The Indiana Supreme Court disallowed multiple robbery convictions when criminal assailants took money from multiple tellers in a credit union, reasoning that the essence of robbery is the taking of property, and therefore property stolen from one owner should constitute one robbery. Allen v. State,
{27} Analyzing this issue in light of New Mexico’s legislative policy, we find the reasoning from the Maryland, California, and Virginia courts persuasive, that robbery is a crime designed to punish the use of violence. To the contrary, we are not persuaded by the arguments put forth by the Indiana and West Virginia courts, that robbery is a property crime and nothing more than aggravated larceny.
{28} Our Court of Appeals has previously noted that robbery is distinct from larceny because it requires, and is designed to punish, the element of force. Brown,
{29} To the extent that some jurisdictions limit the multiplicity of robbery charges due to fear of disproportionate sentences, we generally defer to the judgment of the legislature regarding the appropriate length of sentences. See State v. Archibeque,
{30} We note that in other contexts we have rejected arguments that a single intent with multiple acts can only constitute one crime. See, e.g., DeGraff,
{31} Accordingly, we reject Defendant’s analogy to the single-larceny doctrine and his reliance upon a continuous single intent. We hold that under these facts, where Defendant had the intent to steal only one victim’s property, but used separate and discrete acts of force and threats of force against two victims in an attempt to obtain that property, multiple attempted robbery charges do not violate double jeopardy. When a would-be robber uses force in a separate and distinct manner against multiple victims, multiple convictions for robbery (or attempted robbery) will not be prohibited solely because the robber intends to steal from one owner. 2 Because there were two robbery attempts, and because the second robbery attempt was distinct from the first attempt which constituted the predicate felony for felony murder, we hold that no double jeopardy violation occurred when Defendant was convicted of and sentenced for both attempted armed robbery of Romero and felony murder of Giron.
Ineffective Assistance of Counsel
{32} For a successful ineffective assistance of counsel claim, a defendant must first demonstrate error on the part of counsel, and then show that the error resulted in prejudice. Strickland v. Washington,
{33} Oftentimes, the record on appeal does not provide enough information to adequately determine whether an action was error or caused prejudice. When such questions arise, further evidence is often required. Duncan v. Kerby,
{34} Defendant claims ineffective assistance on the following grounds: (1) trial counsel filed no substantive pre-trial motions, including no motion to dismiss charges on double jeopardy grounds; (2) trial counsel failed to object to hearsay statements during trial; (3) trial counsel stipulated to the admission of testimony from Defendant’s mother to the effect that two guns were stolen from her house the day before the burglary; (4) trial counsel failed to investigate, which led to ineffectual cross-examination and opening statement; (5) trial counsel did not tender jury instructions; (6) trial counsel made an inadequate motion for directed verdict; (7) trial counsel failed to adequately confront witnesses on cross-examination; and (8) trial counsel failed to sever the felon in possession of a firearm charge.
{35} Initially, we note that the stipulation to the testimony of Defendant’s mother and the failure to sever the felon in possession of a firearm charge represent potentially serious failures on the part of trial counsel, which may demand a full-bodied inquiry at an evidentiary hearing on habeas corpus. These charges, like most of the rest of the claimed errors, may implicate tactical decisions made by counsel at or during trial, and are best evaluated during habeas corpus proceedings where trial counsel can provide testimony. Such evidence is also necessary in this case to demonstrate that any alleged errors caused prejudice.
{36} We conclude Defendant has not presented a prima-faeie case of ineffective assistance of counsel on these grounds, and accordingly, we reject Defendant’s ineffective assistance of counsel claim. However, this decision does not preclude Defendant from pursuing habeas corpus proceedings on this issue should he be able to garner evidence to support his claims.
CONCLUSION
{37} Having concluded that Defendant’s convictions for attempted armed robbery and felony murder do not violate the double jeopardy prohibition against multiple punishments, and that Defendant has failed to present a prima-facie claim of ineffective assistance of counsel, we affirm his convictions.
{38} IT IS SO ORDERED.
Notes
. Originally two other individuals were also indicted for their roles in the crime based upon Jaramillo’s testimony, and the three cases were joined. The State subsequently decided that it could proceed only with the prosecution of Defendant and severed the cases for trial.
. We express no opinion as to whether two attempted robberies could occur when the same act of force is used against two victims, e.g., pointing a gun at both at the same time when only one item of property is sought. That question is not before us because Defendant used separate acts of force, at separate times, against Giron and Romero. We reiterate that double jeopardy claims are analyzed on a case-by-case basis to determine if conduct is unitary.
