¶ 1. Bradley Hackl, who murdered his wife, Diane, appeals an order imposing a constructive trust on an undivided one-half interest in *45 his pension. The circuit court imposed the constructive trust after concluding that the pension account had constituted marital property prior to Diane's death, and that, because Bradley murdered her, Diane's interest in the pension "survives her death." Bradley claims the circuit court еrred by failing to follow §§ 766.31(3) and 766.62(5), Stats., which, according to Bradley, establish that Diane's interest in his pension terminated at her death. 1 We conclude, however, that the trial court's order is consistent with the equitable principle, long applied in Wisconsin, that a murderer should not be allowed to benefit from his or her crime. Accordingly, we affirm.
BACKGROUND
¶ 2. Bradley and Diane Hackl were married in 1988. In 1996, as the two were divorcing, Bradley murdered Dianе. Bradley was convicted of the crime and sentenced to prison for life. Bradley had worked as a union mason for almost forty years and had contributed to a pension fund since 1957. From prison, Bradley applied for and began to receive monthly pension benefits.
¶ 3. In probate proceedings regarding Diane's estate, her personal representative asserted that the pension was marital рroperty and claimed an undivided one-half interest in the pension as an estate asset. Bradley objected, arguing that Diane's marital property interest in his pension terminated upon her death, and that the pension must thus be classified as *46 wholly his individual property. The circuit court concluded that Diane's interest in Bradley's pension survived her death and ordered that a constructive trust be imposed on an undivided оne-half of it. Bradley appeals the order. 2
ANALYSIS
¶ 4. Bradley argues that the "terminable interest rule," set forth in §§ 766.31(3) and 766.62(5), Stats., conclusively establishes that any interest Diane may have held in his pension terminated at her death. Section 766.31(3), Stats., provides that "the marital property interest of [a] nonemploye spouse in a deferred employment benefit plan... terminates at the death of the nonemploye spousе if he or she predeceases the employe spouse." Section 766.62(5), Stats., reiterates this provision: "If the nonemploye spouse predeceases the employe spouse, the marital property interest of the nonemploye spouse in all of the following terminates at the death of the nonemploye spouse: (a) A deferred employment benefit plan. ..." (Diane's children do nоt dispute that Bradley's pension falls within the statutory definition of "deferred employment benefit plan." See § 766.01(4)(a), STATS.)
¶ 5. The issue before us is whether these statutes unequivocally bar Diane's estate from claiming any interest in Bradley's pension. It is thus a question of law, which this court reviews de novo.
See Stockbridge Sch. Dist. v. Department of Pub. Instruction Sch. Dist. Boundary Appeal Bd.,
¶ 6. The application of the terminable interest rule set fоrth in §§ 766.31(3) and 766.62(5), STATS., to the present circumstance is an issue of first impression, but our customary approach to statutory interpretation will not assist us in resolving it. The dispute is not over what the statutes say, but what they plainly do not say — how we are to treat a nonemployee spouse's marital interest in a deferred employment benefit plan when that spouse is murdered by the employee spouse. Bradley would have us еnd our inquiry at this point, with a conclusion that because the legislature did not create an exception for the circumstance before us, there is no basis on which a court may conclude that Diane's interest did not terminate on her death. We disagree. Our conclusion, however, does not derive from consulting extrinsic sources to ascertain what the legislature might have intended in this circumstance; rather, we base our decision on an equitable principle that the Wisconsin Supreme Court has never hesitated to apply in situations when a mur *48 derer claims an interest in property acquired as a result of the victim's death. 3
¶ 7. Wisconsin courts have long been committed to the principle that a murderer should not be permitted to profit from his or her crime. The supreme court articulated this principle in 1927, when it statеd:
The equitable doctrine that a man shall not profit by his own wrong dates back centuries in the history of the common law, and is as old as equity itself. It is recognized, as far as we are able to determine, in the laws of all civilized communities. It lies at the foundation of every religious faith. ... It is vitally essential to the administration of justice, and a careful search of our Statutes fails to reveal that it was ever modified or abrоgated. It therefore exists at the present day in Wisconsin, with all the force which it possessed throughout the ages,. ..

Estate of Wilkins,
¶ 8. Twenty-five years later, the court again applied the principle, this time to the murder of one joint tenant by another.
See Estate of King,
"the most equitable [result]... can be justified upon the theory that the murder operates as a severance of the joint tenancy resulting in a tenancy in common whereby the murderer retains ownership to an undivided one-half interest, but gains no title in, or enjoyment of, the other half, which other half vests in the heirs at law and next of kin of the murdered joint tenant."
Estate of Safran,
¶ 9. The supreme court has also clarified since its opinion in
King
that the proper analysis to be applied to bequests is based on principles of equity, resulting in the imposition of a constructive trust, which provides greater flexibility for a court to achievе a just result.
See Will of Wilson,
¶ 10. The legislature in 1982 codified this common law principle with respect to several specific types of property transfers at death. 4 Section 700.17(2)(b), Stats., 1993-94, provides that when one joint tenant kills another, the joint tenancy is severed and the killer loses the right of survivorship in the decedent's property. Section 852.01(2m), Stats., 1993-94, provides that when a person is murdered by someone who would otherwise be an heir, the victim's estate passes as if the killer predeceased the decedent. Section 853.11(3m), STATS., 1993-94, in turn, establishes a similаr disposition scheme for will beneficiaries. Finally, §§ 632.485, 895.43, and 895.435, Stats., 1993-94, ensure in similar fashion that a murderer does not "receive any benefit" from life insurance policies, or from other contracts or death benefits, as a result of a death he or she intentionally causes.
*51 ¶ 11. We acknowledge that the legislature did not adopt a provision similar to the foregoing that addresses the disposition of an employee spouse's pension when that spouse kills the nonemployee spouse. 5 Bradley insists that the absence of a statutory provision indicates that the legislature was unwilling to negate the operation of the terminable interest rule as set forth in §§ 766.31(3) and 766.62(5), Stats., on the present facts. We conclude, however, that the absence suggests only that the legislature failed to contemplate this circumstance when it enacted the terminal interest rule for employee pensions in the marital property act. We view the legislative enactments described above, as well as the recent creation of § 854.14, STATS., 1997-98, as an indication of the legislature's willingness to foster the public policy embodied in the common law principle that a murderer should not profit from his or her crime. (See footnotes 4 and 5.) Finally, we note that the absence of statutes creating exceptions for death transfers of property from which a murderer might benefit did not prevent the supreme court from applying common law equitable principles to bequests and joint tenancies. Thus, we conclude that the legislature's silence on the issue before us does not prevent us *52 from doing, likewise with respect to the terminal interest rule of §§ 766.31(3) and 766.62(5), STATS.
¶ 12. We cоnclude that the common law principle that murderers should not profit from their crimes applies to the facts and statutes presently before us. We must next determine if the trial court fashioned the proper remedy by imposing a constructive trust on what it deemed to be Diane's marital property interest in Bradley's pension. We conclude that it did. The supreme court, in its most recent application of thе principle, endorsed two possible rationales for depriving Bradley of any benefit from the termination of Diane's interest in his pension.
See Estate of Safran,
¶ 13. We can envision an argument that Bradley's murder of Diane should be deemed to have effected a divorce simultaneously wdth Diane's death, thereby vesting title to her marital property interest in the pension in her estate. We believe the rationale for imрosing a constructive trust is much stronger, however. Had the marriage ended in divorce prior to Diane's death, her interest in Bradley's pension would have been determined under § 767.255, STATS., not § 766.62, Stats.
See Mausing v. Mausing,
¶ 14. Moreover, as we have discussed, the legislature has clearly expressed its intent that when a marriage terminates because of the death of a nonemployee spouse, that spouse's interest in the employee spouse's pension is extinguished. Just as imposing a constructive trust on will bequests is viewed as not interfering with statutory directives regarding how wills may be revoked,
see Safran,
¶ 15. Finally, the constructive trust approach "affords a court of equity greater flexibility in arriving at a just result which does not defeat the intent of the deceased."
See Wilson, 5
Wis. 2d at 183,
¶ 16. Consequently, we follow the reasoning set forth in
Wilson
and affirm the trial court's imposition of a constructive trust on Diane's marital property interest in Bradley's pension. Bradley argues, however, that a constructive trust cannot be imposed on a portion of his pension because the requirements for its imposition have not been satisfied. The supreme court has concluded that a constructive trust may be imposed only if (1) title to the property is held by someone who "in equity and good conscience should not be entitled to beneficiаl enjoyment," and (2) title was obtained through "fraud, duress, . . . commission of a wrong, or .. . any form of unconscionable conduct."
See Wilharms v. Wilharms,
¶ 17. This court has recognized a distinction between property acquired by a murderer
as a conse
*55
quence of a
wrongful act and property lawfully acquired by the murderer
prior to
such an act.
See Krueger v. Rodenberg,
¶ 18. We conclude that our holding in
Krueger
is of no assistance to Bradley on the present facts. The property at issue in
Krueger
was "predetermination date property, [which] is treated by the Wisconsin Marital Property Act as if it were [the murderer's] individual property during the marriage."
Krueger,
¶ 19. Bradley also argues, for the first time in his reply brief, that the trial court erred in determining that Diane's marital property interest in his pension amounted to an undivided one-half interest. Section 766.62(2), Stats., provides as fоllows:
A deferred employment benefit attributable to employment of a spouse occurring while the spouse is married and partly before and partly after the determination date is mixed property. The marital property component of that mixed property is the amount which results from multiplying the entire benefit by a fraction, the numerator of which is the period of employment giving rise to the benefit thаt occurred after the determination date and during marriage and the denominator of which is the total period of employment giving rise to the benefit.
Bradley asserts that Diane's interest must be determined by applying this formula which considers both the length of the marriage and the number of years of employment which preceded marriage. As we have noted, however, this argument was not raised in Bradley's opening brief. We do not, as a general rule, address issues raised for the first time in a reply brief, and we will not do so here.
See Estate of Bilsie,
¶ 20. A final issue remains. Diane's children assert that Bradley's appeal was frivolous, and they move this court to award attorney's fees and costs under Rule 809.25(3)(c)2, Stats. In order for us to find Bradley's appeal frivolous under the cited rule, we must conclude that Bradley or his attorney knew, or should have known, that his appeal "was without any reasonable basis in law or equity and could not be sup
*57
ported by a good faith argument for an extension, modification, or reversal of existing law."
Id.
This standard is an objective one, based upon what a reasonable attorney would have, or should have, known under the same or similar circumstances.
See Stern v. Thompson & Coates, Ltd.,
¶ 21. The issue presented in this appeal is one of first impression, involving the application of common law principles to statutes enacted well after most of the relevant precedents were decided. Although we have had little difficulty in deciding that the principles should apply to the operation of §§ 766.31(3) and 766.62(5), STATS., we cannot say that Bradlеy's arguments are without any reasonable basis in law or equity. Accordingly, we deny the motion for sanctions.
CONCLUSION
¶ 22. For the reasons discussed above, we affirm the order of the circuit court imposing a constructive trust on Diane's interest in Bradley's pension. We deny, however, the motion of Diane's children seeking attorney's fees and costs under Rule 809.25(3)(c)2, Stats.
By the Court. — Order affirmed.
Notes
Sections 766.31(3) and 766.62(5), Stats., are quoted and discussed in the text of this opinion. Generally, these statutes provide that a nonemployee spouse's interest in his or her spouse's "deferred employment benefit plan" terminates upon the nonemployee spouse's death.
The circuit court found that Diane died intestate, and it appointed her brother personal representative of her estate. The respondents in this appeal are Diane's three children, who are apparently her heirs. See § 852.01(l)(b), (2m), STATS., 1993-94.
Although we conclude that the issue in this appeal cannot be resolved by consulting extrinsic aids to statutory interpretation, we have endeavored to discover if there is any indication in the legislative history of §§ 766.31(3) and 766.62(5), Stats., that the legislature specifically rejected the creation of an exception for interspousal murder, similar to those which it has enacted regarding other property transfers at death. The terminable interest rule implements a legislative policy decision "to assure an employee spouse full access to benefits in a deferred employment benefit plan during that spouse's retirement years if he or she is predeceased by the nonemployee spouse." See Keith A. Christiansen, Marital Property in Wisconsin § 2.102 (1990). The terminable interest rule thus guards against testаmentary dispositions by the nonemployee spouse of "any part of a deferred employment benefit plan attributable to the employment of an employee spouse." Id. We have been unable to locate any evidence that the issue presently before us arose during the consideration and enactment of these marital property provisions.
See Laws of 1981, ch. 228. The statutes discussed in this paragraph were amended in 1997 to refer over to a newly created provision governing the distribution of property a "killer" might otherwise acquire through an unlawful and intentional killing. See 1997 Wis. Act 188, §§ 13, 109, 139, 175, 231 and 232; and §854.14, Stats., 1997-98. Section 854.14, Stats., applies only to deaths occurring after January 1, 1999, and is therefore inapplicable to the present facts. See 1997 Wis. Act 188, § 233.
The provisions of§ 854.14, STATS., 1997-98, were not effective at the time of Diane's death in 1996. See n.4 above. Under § 854.14(2)(c), the "unlawful and intentional killing of the decedent . . . [rjevokes every statutory right or benefit to which the killer may have been entitled by reason of the decedent's death." Id. (emphasis added). Because the new statute does not apply to Diane's death, and because we decide the present case on common law principles, we do not address whether the statute addresses the termination of a marital property interest under §§ 766.31(3) and 766.62(5), Stats., which results from an inter-spousal murder.
