Opinion by
Richard James Vigil obtained cars to sell on consignment. He sold some of the cars without telling the owners and then kept the proceeds. He also falsified documents and took money from several buyers without conveying title. He went to trial and was convicted of nine offenses: one count of forgery, three counts of offering a false instrument for recording, and five counts of theft, He was sentenced to fifteen years in prison.
Vigil now appeals his convictions and sentence. In part I of this opinion, we consider and reject the arguments presented in Vigil's opening brief, In part II, we consider a multiplicity issue on our own motion. We conclude that two of Vigil's theft convictions must be merged. We therefore affirm the judgment in part and vacate it in part, vacate the sentence, and remand for resentencing.
I. Vigil's Contentions
Vigil challenges his convictions on several grounds. His contentions fail.
A. Charging Document
The prosecution charged Vigil with five counts of offering a false instrument for recording. Of those five counts, Vigil was convicted of three: counts 8, 12, and 18. Vigil contends that these convictions must be reversed because the charging document, a felony information, did not allege certain facts. We see no reason to reverse.
An information is sufficient if it establishes the following:
(a) That it is presented by the person authorized by law to prosecute the offense;
(b) That the defendant is identified therein, either by name or by the defendant's patterned chemical structure of genetic information, or described as a person whose name is unknown to the informant;
(c) That the offense was committed within the jurisdiction of the court or is triable therein;
(d) That the offense charged is set forth with such degree of certainty that the court may pronounce judgment upon a conviction.
§ 16-5-202(1), C.R.S.2009; see Crim. P. 7(b)(2) (stating identical requirements); People v. Williams,
Here, the information satisfied the necessary requirements. The charges were filed under authority of the elected district attorney. Each of the pertinent counts identified Vigil by name and alleged the necessary jurisdictional facts; each identified the elements of filing a false instrument for recording; and each contained sufficient detail to apprise Vigil of the particular offense of which he was accused.
1
We therefore conclude that the information was sufficient. See People v. Melillo,
We acknowledge that the charges failed to identify the particular statement or assertion alleged to be false. See People v. Fueston,
There is no question that, on these charges, Vigil was able to identify the unlawful transactions so that he could form his defense. (Although not essential to our analysis, we note that Vigil's defense was successful on two of the five charges.) And there is no question that Vigil can guard against further prosecution for these offenses. See United States v. Whitman,
We are aware that, in some cases, lack of specificity has been held to constitute a fatal defect in the charging document. But we view those cases as distinguishable because, in each case, the defect would have precluded the preparation of a meaningful defense. See, e.g., People v. Tucker,
Because Vigil was able to prepare a defense, because he did not object to the charges or request a bill of particulars, and because he did not allege (much less demonstrate) prejudice, his argument fails See Williams,
B. Unanimity Instruction
Vigil contends that the court should have given a special unanimity instruction to guide the jury's deliberations on the theft charges. His argument is this:
1. When it enacted the theft statute, the legislature combined several distinct offenses into one crime. See § 18-4-401, C.R.S.2009; People v. Quick,718 P.2d 1282 , 1287 (Colo.1986).
2. Because the statute does not expressly state otherwise, courts should assume that the legislature "intended the formerly distinct offenses to retain their 'offense' status with its attendant unanimity requirements." United States v. Edmonds,80 F.3d 810 , 822 (3d Cir.1996). Accordingly, trial courts must ensure that jurors unanimously agree *447 on the theory that underlies any particular theft conviction.
3. Here, the court failed to ensure that the jurors either were unanimous in finding that Vigil knowingly obtained a thing of value "without authorization" or were unanimous in finding that he knowingly did so "by deception." The court similarly failed to ensure that the jurors were unanimous in finding that Vigil took a thing of value "with intent to permanently deprive" or were unanimous in finding that he "knowingly used or concealed the thing of value in such a manner as to deprive the [vie-tim] permanently of its use or benefit."
Because Vigil did not make this argument or request a unanimity instruction at trial, we review only for plain error. Woertman v. People,
Generally, jurors need not agree about the evidence or theory by which a particular element is established, People v. Palmer,
Given the lack of authority supporting Vigil's contention, we conclude that the alleged error cannot be regarded as plain or obvious. We therefore reject Vigil's contention.
C. Sufficiency of the Evidence
When reviewing the sufficiency of the evidence, we determine whether any rational trier of fact might accept the evidence, taken as a whole and in the light most favorable to the prosecution, as sufficient to support a finding of guilt beyond a reasonable doubt. People v. McIntier,
Here, contrary to Vigil's view, the evidence is sufficient to support the jury's verdict on the disputed charges:
e Count 3. The evidence supports a reasonable inference that Vigil lied so that the buyer would give him money for a car that Vigil did not own.
eCounts 4 and 10. The charging doeument alleged that Vigil stole the victims' cars. The evidence proved these offenses, and Vigil does not suggest otherwise. Instead, relying on language in a jury instruction, he argues that the prosecution failed to prove that he stole the victims' money. This argument fails because the sufficiency of evidence is measured "against the elements of the offense, not against the jury instructions." United States v. Bomski,125 F.3d 1115 , 1118 (7th Cir.1997); see People v. Gonzales,666 P.2d 123 , 127 (Colo.1983) ("'The relevant question is whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could find that each of the essential elements of the crime charged has been proven beyond a reasonable doubt."); see also United States v. Morton,412 F.3d 901 , 904 (8th Cir.2005) (whether the jury was properly instruct *448 ed does not affect a review for sufficiency of the evidence).
e Count 6. The evidence supports a reasonable inference that Vigil forged a signature on a bill of sale so that it would appear, to a potential buyer or others, that Vigil had purchased the car. Although there is no evidence that Vigil used the document to defraud any person, one could reasonably infer that he prepared it with fraudulent intent.
D. Uncharged Misconduct
During his direct examination, Vigil said that he had been unable to pay back the victims because he was jailed pending trial. On cross-examination, the prosecutor sought to clarify that Vigil was not being held on his current charges. Defense counsel conceded that this was a proper line of inquiry and asked only that Vigil not be required to specify the nature of the crimes for which he was being held. The court granted defense counsel's request, and the prosecutor adhered to the court's ruling.
Under these cireumstances, we conclude that any error in the court's ruling was invited. See People v. Stewart,
E. Severance
During a pretrial hearing, the court asked defense counsel to state his position on an earlier filed motion for severance of charges. Counsel responded that he would leave the matter to the court's discretion. Because that exchange did not constitute a renewal of Vigil's motion, it did not preserve Vigil's appellate argument about severance. See People v. Aalbu,
F. Prosecutorial Misconduct
None of the prosecutor's remarks in closing argument was flagrant or glaringly improper. We therefore decline to grant relief for plain error. See People v. Williams,
II. Multiplicity
We now consider a multiplicity issue that we raised on our own motion. We conclude that two theft convictions must be merged into one.
A. Introduction
"Multiplicity is the charging of the same offense in several counts, culminating in multiple punishments." Quintano v. People,
To determine whether a defendant's conduct may support multiple convictions, we first identify the legislatively defined unit of prosecution. We then examine the evidence to determine whether the defendant's conduct constituted factually distinct offenses. Id. at 215; Quintano,
In Roberts v. People,
Roberts was announced after the parties had filed their briefs in this appeal. Because some of Vigil's thefts occurred with *449 in six months of each other, we requested supplemental briefing on the applicability of Roberts, We conclude that Roberts applies here.
In so doing, we make three observations.
First, we think it appropriate to have raised this issue on our own motion. Double jeopardy claims implicate fundamental rights. See Patton v. People,
Second, we recognize that the legislature has amended the theft statute to dispense with the mandatory six-month unit of prosecution. See § 18-4-401(4)(a)-(b) (effective May 11, 2009, providing that "two or more ... thefts may be aggregated and charged in a single count" (emphasis added)). But we conclude that Vigil is not affected by this change because his offenses were all committed before the amendment's effective date.
Third, we acknowledge that, in amending the theft statute, the legislature disavowed any intent to have created a mandatory unit of prosecution. See Ch. 244, see. 1(a), 2009 Sess. Laws at 1099 (declaring that the intent in adopting prior versions of the statute was "to allow, but not require," the aggregation of thefts). But we decline to give this declaration retroactive effect, A legislative statement "cannot control the interpretation of an earlier enacted statute." O'Gilvie v. United States,
B. Applying Roberts
The unit of prosecution identified in Roberts is easy to apply if the defendant's thefts all occur within a single six-month period (the defendant may sustain only one theft conviction), or if the defendant's thefts are all separated by more than six months (each theft can support a separate convietion). But the issue is more complicated if the thefts may be grouped in various ways.
Consider a hypothetical case in which a person commits a theft every four months for a year (one each in January, April, July, and October). Under Roberts, one could aggregate these thefts in two ways.
First, one could group the earliest two thefts (January and April) into one six-month period, and group the last two thefts (July and October) into another six-month period. This approach would result in two theft convictions:
*450 [[Image here]]
Second, one could group the middle two thefts (April and July) into one six-month period. This approach would place the earliest (January) and latest (October) thefts into separate six-month periods and would result in three convictions:
[[Image here]]
Both approaches reflect a legitimate application of the legislatively defined unit of prosecution. Therefore, the prosecution would be free to employ either approach in charging the defendant. See People v. Renander,
On appeal, however, a reviewing court must employ the approach that will maximize the effect of a jury's verdict. See People v. Rodrigues,
We examine the record to determine whether the evidence is sufficient to support a factual finding that the thefts occurred in separate six-month periods. See Abiodun,
Applying these criteria, we conclude that the evidence will support four convie-tions.
1. Count 1. Vigil was charged with theft from T.R. between January 1 and March 31, 2002. The evidence supports a reasonable inference that the crime was complete as early as January 5, 2002 (when TR. gave Vigil cash for a car). Because this theft was committed more than six months before any other, it will support one conviction under Roberts.
2. Count 2. Vigil was charged with theft . from R.M. between September 1, 2002, and July 31, 2008. The evidence supports a reasonable inference that this theft was complete as early as January 28, 2008 (when R.M. gave Vigil cash for a car). Because this theft occurred more than six months after the theft described in count 1, and because it stands outside the six-month period that comprises counts 3 and 10, it supports a single conviction.
3. Counts 3 and 10. Vigil was charged in Count 3 with theft from victims T.N. and E.N. between May 1 and June 30, 2003. But the evidence shows that the crime was committed on a single day, May 12, 2008. In Count 10, Vigil was charged with theft from victims R.A. and M.A. between September 1, 2003, and February 29, 2004. But the evidence shows that the crime was committed in September 2008. Because both thefts occurred within the same six-month period, they constitute one theft under Roberts. Therefore, *451 counts 3 and 10 must be merged into a single conviction for theft as a class 4 felony. 2
4. Count 4. Vigil was charged with theft from victim J.Z. between October 1, 2003, and February 29, 2004. The evidence supports a reasonable inference that the crime was completed as late as December 15, 2003, when Vigil sold J.Z.'s car. Because this theft occurred outside the six-month period that comprises counts 3 and 10, it supports one theft conviction.
C. Resentencing
Because counts 3 and 10 must be merged, we remand for correction of the mittimus and resentencing on that single count.
To the extent that they continue to be relevant, we reject Vigil's challenges to the court's exercise of discretion in imposing consecutive terms. The court did not rely on evidence outside the record, nor did it fail to consider mitigating cireumstances.
III. Conclusion
The judgment is vacated insofar as it reflects separate convictions for counts 3 and 10; the sentence is vacated; and the case is remanded with directions to merge those counts and to resentence Vigil on the merged count. In all other respects, the judgment is affirmed.
Notes
. The pertinent charges are similar in form and content. Here is a representative example: That on or about December 18, 2003, at the City and County of Denver, State of Colorado, Richard James Vigil unlawfully, feloniously, and with intent to defraud, presented or offered a written instrument, namely: DUPLICATE CERTIFICATE OF TITLE # 10R564092 and POWER OF ATTORNEY FOR MOTOR VEHICLE ONLY, relating to or affecting real or personal property or directly affecting contractual relationships, to a public office or a public employee, namely: COLORADO DE-PARIMENT OF REVENUE, MOTOR VEHICLES DIVISION, with the knowledge or belief that the written instrument would be registered, filed, or recorded or become a part of the records of that public office or public employee, and knowing that the written instrument contained a material false statement or material false information; in violation of section 18-5-114(1), CRS.
. The People argue that, by aggregating the value of the merged counts, we may order the district court to impose a conviction for theft as a class 3 felony. We disagree. Although the classification of a theft is determined by its aggregate value, Vigil cannot be convicted of a crime greater than one with which he was charged. See Schmuck v. United States,
