The sole issue before us in this appeal is whether the prospective abrogation of the common law “year and a day” rule as pronounced in the Supreme Court’s recent decision in State v. Vance, 828 N.C. 613, 403 S.E.2d 495 (1991) should prevent the defendant’s prosecution for murder where the murderous act was committed before the date of abrogation, but the victim’s death did not occur until after the date of abrogation. We conclude that it should not and vacate the order dismissing the indictment.
Prior to our Supreme Court’s decision in Vance, the common law in North Carolina required that in order to charge a defendant with murder, the victim must have died within a year and a day of the murderous act. State v. Orrell, 12 N.C. (1 Dev.) 139 (1826). However, that rule was judicially abolished in Vance, supra, filed on 2 May 1991 with the final mandate issued 22 May 1991. The Supreme Court in Vance held that any rationale for the “year and a day” rule was anachronistic today, and that the rule was no longer part of the common law of North Carolina for any purpose. Vance, at 619, 403 S.E.2d at 499.
However, the Vance court also concluded that:
[T]he prohibitions against ex post facto laws embodied in the fifth and fourteenth amendments to the Constitution of the United States require that we give this decision abolishing the year and a day rule prospective effect only.
Id. at 621, 403 S.E.2d at 500. Thus, the Vance court overturned defendant’s conviction for second degree murder because the murderous act and the resultant death of the victim both occurred previous to the abolition of the year and a day rule. The Vance court expressly followed the proposition that unforeseeable judicial modifications of criminal law may trigger the ex post facto clauses of the state and federal constitutions and therefore applied the abolition of the year and a day rule prospectively. Id. We are *286bound to follow this decision and cannot, as the State invites us to do, reconsider the question of whether or not the prohibition against ex post facto laws may be infringed upon by the retrospective operation of a judicial decision. The North Carolina Supreme Court has already answered that question affirmatively as applied to the abrogation of the year and a day rule.
The issue before this Court, however, is not identical to that issue before the Vance court. In Vance, both the murderous act and the death of the victim occurred at a time when the “year and a day” rule was still the law in North Carolina. There was no question that a retroactive application of the abolition of the rule to those facts would violate the ex post facto clauses of the United States and North Carolina Constitutions. However, the facts of the instant case differ in that, while the murderous act occurred before the decision in Vance abolishing the “year and a day” rule, Mrs. Robinson’s death did not occur until after that decision. We do not believe from the language in Vance that the Supreme Court expressly contemplated the unique, and in all probability, rare factual situation presented by this case.
Because Vance did not attempt to address the specific issue before this Court, we find little guidance in its language. The only language in the Vance decision which points to the date considered by the court to be significant for purposes of ex post facto application of the abolition of the year and a day rule is as follows:
To apply today’s decision abrogating the year and a day rule to permit the defendant to be convicted of murder in the present case would, at the very least, permit his conviction upon less evidence than would have been required to convict him of that crime at the time the victim died and would, for that reason, violate the principles preventing the application of ex post facto laws . . . (citation omitted). Retroactive application of our decision today, so as to uphold the judgment for murder in the present case, clearly would be to apply this decision to events occurring before this decision and severely disadvantage the defendant. (Emphasis added.)
Vance, at 622, 403 S.E.2d 501. We consider this language to be some evidence that the Supreme Court viewed the critical date, i.e. the day the “events occur,” for preventing ex post facto application of their decision to abolish the year and a day rule, as being the date the victim dies rather than the date of the murderous *287act. Applying that interpretation to the facts in the present case must result in allowing defendant to be tried for murder, since at the date of Mrs. Robinson’s death, the “year and a day” rule was no longer the law in this State. Unlike Vance, defendant’s conviction in this case would not be permitted upon less evidence than would have been required at the time of the victim’s death.
Defendant argues, however, that our Supreme Court, in State v. Detter, 298 N.C. 604, 260 S.E.2d 567 (1979) has already decided that the date the murderous act was committed, rather than the date of the victim’s death, should be the decisive date in determining whether a change in the law may be applied without violating the ex post facto provisions of our constitutions. In Detter, the defendant poisoned her husband who died several months later. At the time of the administration of the poison, the penalty for first degree murder was life imprisonment. However, after the poisoning, but before the husband’s death, the Legislature enacted N.C. Gen. Stat. 15A-2000 et seq. which permitted the imposition of the death penalty as a punishment for first degree murder. The court held that the law in effect at the time of the murderous act (poisoning) controlled rather than the law in effect at the time of the husband’s death. Id. at 638, 260 S.E.2d at 590. To impose the death penalty on that defendant, said the court, would constitute ex post facto legislation.
However, in reaching its decision, the Detter court discussed an earlier decision, State v. Williams, 229 N.C. 348, 49 S.E.2d 617 (1948), in which the court held that, for the purpose of deciding whether a defendant was guilty of the crime of accessory after the fact to murder, the time of death was the time the murder was committed, rather than the time the fatal blow was struck. Thus, one who rendered aid to the murderer after the murderous act, but before the victim died, could not be guilty’, of accessory after the fact to murder because the crime was not complete until the resulting death occurred. Id. The Detter court limited its holding to the facts before it stating:
[W]hen it becomes necessary to choose between the time the fatal blow is struck or the time of death for some special purpose such as accessory after the fact to murder or to determine if a certain punishment is barred by the ex post facto clause the choice should be dictated by the nature of the inquiry.
Id., at 638, 260 S.E.2d at 590.
*288In our opinion, to allow defendant to be prosecuted for murder under the limited circumstances before us does not violate the holdings in Vance or Detter. Rather, we conclude from the language in Vance, and the purposes behind the abolition of the “year and a day” rule, that defendant should be prosecuted for the brutal and senseless murder of his wife. The facts of the instant case are significantly different from Vance and the inquiry different from that in Detter. The Supreme Court specifically stated in Vance that its primary concern was that a retroactive application of the abolition of the “year and a day” rule would allow the defendant to be convicted of murder upon less evidence than would have been required at the time the victim died thereby violating the ex post facto clauses. Vance at 622, 403 S.E.2d at 501. Moreover, the “nature of the inquiry” differs from that in Detter, where the court was dealing with an ex post facto application of a legislative change in punishment rather than a determination as to whether a crime had been completed. In this case, defendant was not vulnerable to a murder charge until Mrs. Robinson actually died. At the time of her death, the law in effect did not require that she have died within a year and a day of defendant’s acts. This case is not one like Vance in which the defendant committed a murderous act, the victim died more than a year and a day later, and the law was subsequently changed to permit an otherwise impermissible prosecution.
We hold, on the facts before us, that the relevant date of Mrs. Robinson’s murder for the purposes of determining whether the prosecution of defendant violates the ex post facto clauses of the North Carolina and Federal Constitutions, is the date upon which she died. On that date, the year and a day rule had previously been abrogated. Therefore, to indict this defendant for murder does not violate the mandate in State v. Vance that we apply its decision prospectively in order to avoid violation of the ex post facto clauses of those constitutions. The order dismissing the bill of indictment must be vacated and this case remanded to the Superior Court of Guilford County for further proceedings.
Vacated and remanded.
Judges WELLS and ORR concur.
