Following his guilty plea to an amended charge of second degree murder, the district court for Saunders County sentenced James D. Marrs to “a term of imprisonment of not less than the *574 rest of his life nor more than the rest of his life.” Marrs appeals the sentence. We affirm.
BACKGROUND
On May 5, 2004, Marrs was charged with first degree murder in the June 30, 2003, death of Sharron Erickson of Colon, Nebraska. After counsel was appointed to represent him, Marrs entered a plea of guilty to an amended charge of second degree murder. At Marrs’ sentencing hearing, the prosecutor read into the record a letter from the sister of the victim which stated in part that Marrs was a “ ‘terrorist’ ” to Erickson and “ ‘to the people of Colon who lived in fear knowing a murderer was out there.’ ”
In summarizing the facts of the case, the prosecutor informed the court that an autopsy had determined that the victim died from “manual strangulation” and that in addition, she suffered “multiple cuts and bruises as a result of blunt trauma to her head, nose, face, and legs.” The prosecutor noted that the victim had “multiple defensive wounds on the left-side of her body because of the desperate acts she did in trying to fight back.” The prosecutor described the following sequence of events:
While [Erickson] was sleeping, the defendant climbed a six-foot fence and broke into a screen door that was pried open with a chisel, kicked up the wooden storm door setting off an alarm, and cutting her phone line.
At some point [Erickson] awoke, and apparently grabbed an unloaded Beretta that she kept in her house. When a struggle ensued, the defendant followed her into her garage, continued to beat her and strangle her with [his] hands. At some point he got tired and couldn’t finish the job and had to stand on her throat to finally kill her.
After both sides had presented their arguments and immediately prior to imposing sentence, the district judge stated in part:
You have deprived the community of a valuable citizen and have taken a loved one away from her family.
[Nothing] I can say today or do today or that you could say or do . . . would change the fact that your actions terrorized your community. You placed its residents under fear and suspicion.
The judge’s comments before pronouncing sentence also included the following:
*575 The facts concerning the offense at issue show that it was premeditated and violent. You admitted that you were using substances on the night of the offense.
You went to the residence of the victim and you cut the phone lines. You broke into the residence with a chisel. At the residence you hit the victim who was unable to phone for help. The struggle continued in the victim’s garage where you manually strangled the victim to death, an act which required tremendous and violent force.
The court then sentenced Marrs to a “term of imprisonment of not less than the rest of your life, nor more than the rest of your life.” He filed this timely appeal.
ASSIGNMENTS OF ERROR
Marrs assigns, restated, renumbered, and consolidated, that the district court erred in (1) fixing an identical minimum and maximum term of imprisonment, (2) usurping the constitutional power of the Board of Parole and imposing an unconstitutional sentence, and (3) imposing an excessive sentence based on personal bias.
STANDARD OF REVIEW
Statutory interpretation presents a question of law, for which an appellate court has an obligation to reach an independent conclusion irrespective of the determination made by the court below.
State
v.
Robinson,
The constitutionality of a statute is a question of law, regarding which the Nebraska Supreme Court is obligated to reach a conclusion independent of the determination reached by the trial court.
State v. Moyer,
Sentences within statutory limits will be disturbed by an appellate court only if the sentences complained of were an abuse of judicial discretion.

ANALYSIS
Murder in the second degree is a Class IB felony for which the maximum sentence is life imprisonment and the minimum *576 sentence is 20 years’ imprisonment. Neb. Rev. Stat. §§ 28-105(1) (Cum. Supp. 2004) and 28-304(2) (Reissue 1995). Marrs argues that his sentence was unlawful because the minimum and maximum terms were the same: life imprisonment. He argues that the sentence was not a permissible indeterminate sentence and that it usurped the constitutional power of the Board of Parole. Alternatively, Marrs argues that the sentence was excessive.
Indeterminate Sentence
Marrs’ first argument is premised upon Neb. Rev. Stat. § 29-2204 (Cum. Supp. 2004), which provides in pertinent part that
in imposing an indeterminate sentence upon an offender the court shall:
(ii) Beginning July 1, 1998:
(A) Fix the minimum and maximum limits of the sentence to be served within the limits provided by law for any class of felony other than a Class IV felony, except that when a maximum limit of life is imposed by the court for a Class IB felony, the minimum limit may be any term of years not less than the statutory mandatory minimum. If the criminal offense is a Class IV felony, the court shall fix the minimum and maximum limits of the sentence, but the minimum limit fixed by the court shall not be less than the minimum provided by law nor more than one-third of the maximum term and the maximum limit shall not be greater than the maximum provided by law; or
(B) Impose a definite term of years, in which event the maximum term of the sentence shall be the term imposed by the court and the minimum term shall be the minimum sentence provided by law.
Marrs' contends that this statute does not permit an indeterminate sentence fixing both the minimum term and the maximum term at life imprisonment for second degree murder. He argues that the sentence imposed upon him should thus be construed as setting only a valid maximum term of life imprisonment and that the minimum term of 20 years’ imprisonment should be imposed by operation of law. See,
State
v.
Gass,
Under prior versions of § 29-2204, an indeterminate sentence could not be imposed for second degree murder offenses committed prior to September 9, 1993. See
State v. Secret,
Marrs notes, correctly, that because
Schnabel
did not present the issue of whether the law required the minimum term of an indeterminate sentence for a Class IB felony to be lower than the maximum term, our statement that it did not was dicta. Relying primarily on authority from other jurisdictions, Marrs argues that there must be a difference between the maximum and minimum terms of an indeterminate sentence. See,
People
v.
Buxton,
The Nebraska Court of Appeals has reached conflicting conclusions on this issue. In
State
v.
Wilson,
We addressed an indeterminate sentencing issue in
State v. Urbano,
In this case, we conclude that the district court pronounced an indeterminate sentence in which the minimum and maximum terms were the same. Unlike the circumstance in Urbano, we find no statutory requirement that the affirmatively stated minimum term for a Class IB felony sentence be less than the maximum term. Although § 29-2204(l)(a)(ii) permits a sentencing judge imposing a maximum term of life imprisonment for a Class IB felony to impose a minimum term of years not less than the statutory mandatory minimum, it does not require the judge to do so. *579 Accordingly, we reject Marrs’ argument that his sentence was impermissible under the applicable sentencing statutes.
Constitutional Claim
Marrs’ argument that his sentence unconstitutionally usurped the authority of the Board of Parole was not presented to the district court. Generally, a constitutional question not properly raised in the trial court will not be considered on appeal.
State v. Conover,
Neb. Rev. Stat. § 83-1,110(1) (Cum. Supp. 2004) provides that “[e]very committed offender shall be eligible for parole when the offender has served one-half the minimum term of his or her sentence . . . .” Marrs argues that by setting the minimum term of his sentence as life imprisonment instead of a term of years, the district court usurped the constitutional authority of the Board of Parole. That authority is derived from article IV, § 13, of the Nebraska Constitution, which provides:
The Legislature shall provide by law for the establishment of a Board of Parole and the qualifications of its members. Said board, or a majority thereof, shall have power to grant paroles after conviction and judgment, under such conditions as may be prescribed by law, for any offenses committed against the criminal laws of this state except treason and cases of impeachment. The Governor, Attorney *580 General and Secretary of State, sitting as a board, shall have power to remit fines and forfeitures and to grant respites, reprieves, pardons, or commutations in all cases of conviction for offenses against the laws of the state, except treason and cases of impeachment. The Board of Parole may advise the Governor, Attorney General and Secretary of State on the merits of any application for remission, respite, reprieve, pardon or commutation but such advice shall not be binding on them. The Governor shall have power to suspend the execution of the sentence imposed for treason until the case can be reported to the Legislature at its next session, when the Legislature shall either grant a pardon, or commute the sentence or direct the execution, or grant a further reprieve.
The powers and duties of the Board of Parole are set forth in Neb. Rev. Stat. § 83-192 (Reissue 1999), which provides for review of the record of committed offenders under various circumstances. Section 83-192(1 )(f)(v) provides in part:
If a committed offender is serving a minimum life sentence, his or her record shall be reviewed during the first year of incarceration and every ten years thereafter until such time as the sentence is commuted. If such sentence is commuted, the committed offender’s record shall be reviewed annually when he or she is within five years of his or her earliest parole eligibility date.
The Nebraska Board of Pardons has the unfettered discretion to grant or deny a commutation of a lawfully imposed sentence for any reason or for no reason at all.
Otey v. State,
The minimum life sentence imposed upon Marrs does not itself restrict or usurp any power of the Board of Parole as defined in the constitution or parole eligibility statutes. Marrs’ constitutional argument is without merit.
Excessive Sentence Claim
Marrs argues that his sentence was excessive “because the length of the sentence was affected by the judge’s personal bias towards the crime committed.” Brief for appellant at 34. He contends that the remarks of the district judge at the time of sentencing, as set forth above, are indicative of personal bias. Marrs
*581
relies on
State v. Pattno,
When imposing a sentence, a sentencing judge should consider the defendant’s (1) age, (2) mentality, (3) education and experience, (4) social and cultural background, (5) past criminal record or record of law-abiding conduct, and (6) motivation for the offense, as well as (7) the nature of the offense, and (8) the amount of violence involved in the commission of the crime.
State v. Vasquez, 271
Neb. 906,
CONCLUSION
For the reasons discussed above, we conclude that Marrs’ assignments of error are without merit and affirm the judgment of the district court.
Affirmed.
