By order of this Court, we decided to review the decision of the Court of Appeals in this case, State v. Romero, 114 Idaho 92, 753 P.2d 828 (1988). The Court of Appeals summarized the facts as follows:
Miguel Acuna Romero was convicted of voluntary manslaughter following a jury trial. The district court sentenced him to a determinate period of fifteen years in the custody of the Board of Correction.
A review of the facts is appropriate. On October 29, 1986, shortly after 11:00 p.m., Robert Thompson was crossing a parking lot in Pocatello, Idaho. Romero and a co-defendant, Jerry Griffith, and several other youths were nearby. Thompson was wearing a Halloween mask and made a gesture as he passed the group. Griffith entered into a confrontation with Thompson. Romero soon joined Griffith in this direct confrontation. During the course of this fight, Griffith verbally baited Thompson and then struck him. As the fight continued, Thompson struck Romero. Thereafter, Thompson attempted to retreat but Romero and Griffith continued to press the attack. Eventually Romero and Griffith, acting in concert, knocked Thompson to the ground. From that point on, both Romero and Griffith delivered multiple powerful shoe and boot blows to Thompson’s head. These blows were of sufficient force to cause Thompson’s death.
State v. Romero, 114 Idaho at 93, 753 P.2d at 829.
Romero was tried on the charge of first degree murder requiring the prosecution to prove a “deliberate and premeditated killing.” See I.C. § 18-4004.1 However, after a five day trial the jury returned a guilty *393verdict on the lesser included offense of voluntary manslaughter.
Romero was summoned for sentencing only one business day after the trial. Prior to any argument by Romero’s defense counsel, or the prosecutor for that matter, the trial judge, exhibiting an already made-up mind, announced that a fixed sentence would be imposed. Furthermore, notwithstanding a defense request for a presentence investigation report, and a defense objection to the lack thereof at sentencing, the trial court refused to order a presentence investigation report (PSR). Subsequently, Romero was sentenced to a fixed fifteen year term, the maximum term of confinement authorized by I.C. § 18-4007(1).
The dispositive issue on this appeal, wholly unaddressed by the Court of Appeals, but nevertheless raised by Romero,2 is the trial court’s failure to utilize a PSR. That failure requires that the sentence be vacated and the cause remanded for resentencing after the Court has required and obtained a presentence investigation and report.
After a jury’s determination of guilt, it is essential that the court receive all available adequate information about the defendant, before imposing a sentence which hopefully will be commensurate with the crime for which the defendant has been convicted. Idaho Judge’s Sentencing Manual, § 5.1-1.3 Nevertheless, the trial court flatly refused to order and use a PSR, notwithstanding a timely objection made by Romero’s counsel. Fundamentally, the PSR is used to assist the “court in *394individualizing a rational sentence for the defendant.” Id. at 5.52 (emphasis added). Simply put, the compelling need for information about the defendant at sentencing cannot be arbitrarily disregarded. Moreover, a PSR should be made in every case where incarceration for one year or more is a possible disposition, where the defendant is less than 21 years old, or where the defendant is a first offender. Id. at 5.2-A. Romero, a 20 year old first offender, was sentenced to a fixed 15 year term. Under all three considerations, a PSR should have been ordered.
The trial court’s failure to order a presentence investigation and presentence report contravenes the Idaho Judge’s Sentencing Manual and ABA standards. More fundamentally, the court’s failure clearly violates mandatory Idaho Criminal Rules and case precedent. Idaho Criminal Rule 32 provides:
Standards and procedures governing presentence investigations and reports.— The following standards and procedures shall govern presentence investigations and reports in the Idaho courts: '
(a) When presentence investigations are to be ordered. The trial judge need not require a presentence investigation report in every criminal case. The ordering of such a report is within the discretion of the court. With respect to felony convictions, if the trial court does not require a presentence investigation and report, the record must show affirmatively why such an investigation was not ordered.
(Emphasis added). This rule has been interpreted to mean that where a PSR is not ordered, the record must alternatively establish a valid reason why. State v. Goldman, 107 Idaho 209, 211, 687 P.2d 599, 661 (Ct.App.1984). Thus, it is very much in order that the record be examined to ascertain by what reasoning the trial court refused to order a PSR.
The trial court stated only this: “since probation is not a viable alternative in this case, it is deemed unnecessary to require a presentence investigation and report thereof.” This reasoning is wholly insufficient. Only after the sentencing court has considered a PSR is the court positioned to make an informed decision regarding the viability of probation. By way of comparison, if a defendant is convicted of first degree murder — and subject to the death penalty — probation in all probability is likewise not a “viable alternative.” However, the failure to consider a PSR in such a circumstance would without question constitute reversible error. See I.C.R. 33.1. Thus, we conclude that the trial court’s refusal to order a PSR on the basis that probation is not a viable alternative is not a valid reason under the I.C.R. 32.4
*395Furthermore, Idaho precedent mandates that the trial judge order a presentence investigation prior to sentencing. In State v. Goldman, 107 Idaho 209, 687 P.2d 599 (Ct.App.1984), the trial court refused to order a PSR or update a PSR prepared several months earlier. The Court of Appeals vacated Goldman’s sentence, holding that even though Goldman had not objected to the lack of a PSR, the absence of an objection did not excuse noncompliance with Rule 32: “The rule is there to be followed.” 107 Idaho at 211, 687 P.2d at 602, quoting State v. Toohill, 103 Idaho 565, 566, 650 P.2d 707, 708 (Ct.App.1982) (emphasis added). Romero, conversely, did raise that issue. This case, then, is even more compelling than Goldman. Strangely, the Court of Appeals did not apply nor cite its Goldman decision of which we specifically note our approval.5
Our decision today does not unsettle prior case law which provides that a PSR need not be ordered in every case. On rare occasions the sentencing court may have sufficient information before it to properly come to a decision as to an appropriate sentence. For example, in State v. Powers, 100 Idaho 614, 603 P.2d 569 (1969), where the district court at sentencing utilized the information contained in the defendant’s PSR used only nine days earlier at sentencing for an another unrelated drug offense, we concluded: “Absent a showing of some material change in defendant’s circumstances in the nine day interim it was not error to reuse the same report.” 100 Idaho at 616, 603 P.2d at 571.6 In the case at bar, by contrast, the record shows that the sentencing court had no independent information to vitiate the need for a PSR.7
*396Trial judges are vested with the weighty responsibility of sentencing those individuals unable to conduct themselves within the bounds of our criminal laws. In Idaho there are four goals of criminal punishment:
(1) protection of society,
(2) deterrence of the individual and the public generally,
(3) possibility of rehabilitation, and
(4) punishment or retribution for wrongdoing.
State v. Toohill, 103 Idaho 565, 569, 650 P.2d 707, 711 (Ct.App.1982); State v. Wolfe, 99 Idaho 382, 384, 582 P.2d 728, 730 (1978); State v. Moore, 78 Idaho 359, 363, 304 P.2d 1101, 1103 (1956). Without the crucial information provided in such sources as a PSR, it is impossible for a sentencing court to make an informed decision necessary to promote these four goals.
This Court over 30 years ago stated that “the law recognizes that the previous character, good or bad, of one convicted should be considered in fixing the punishment.” State v. Weise, 75 Idaho 404, 411, 273 P.2d 97, 101 (1954). Here, Romero was sentenced by a judge who did not follow the *397mandates of court rules or case precedent, thereby depriving himself of the information which should be at hand in fashioning an appropriate sentence. Accordingly, the judgment of the district court insofar as it imposes sentence is vacated, and the cause remanded for resentencing. The opinion of the Court of Appeals is vacated.
HUNTLEY and JOHNSON, JJ. concur.. The crime of voluntary manslaughter is defined as an unlawful killing "upon a sudden quarrel or heat of passion.” I.C. § 18-4006. The jury’s decision to reject the prosecutor's demand for a first degree murder conviction and to conclude that Thompson’s death resulted from a sudden quarrel or heat of passion is due to the testimony of the state’s witness Erika Benson. She stated that Romero was the first party present to be physically attacked. She testified that after Thompson removed his Halloween mask he struck Romero in the face, causing Romero to bleed badly. The testimony of the other state witnesses, Glenda Essick, Scott Elliot, and Michelle Walter, supports Benson’s testimony. Further, according to emergency room hospital records, Romero’s left eye was still swollen shut eleven hours after the fight. *393The testimony of the witnesses makes it clear that Romero went to the side of the small Griffith when it appeared that the larger Thompson and Griffith might engage in a fight. The Court of Appeals apparently did not see it important to ascertain who struck the first blow. That was also the start of the fight, which the Court of Appeals account did not establish. The shoes mentioned in its opinion were tennis shoes worn by Romero; the boots were those of Griffith.
. Defendant’s opening brief filed with the Court of Appeals states:
Judge Hargraves uncharacteristically announced his intention to fix the defendant’s sentence at the very outset of the hearing, before even hearing the pleas of defendant’s counsel for a less harsh result. (Tr., p. 371, 1. 15-16) The sentencing was conducted without the benefit of a presentence investigation over the objection of Mr. Romero’s attorney.
App. Brief at 2. Three of the nine points and authorities cited in the brief concern the lack of the PSR:
VI.
After the determination of guilt it is essential that the court receive adequate information about the defendant before handing down the sentence. Idaho Judge’s Sentencing Manual, § 5.1-1.
VII.
Although the trial judge need not order a presentence investigation report in every criminal case, if the trial court does not require presentence investigation, the record must show affirmatively why such an investigation was not ordered. Rule 32, Idaho Criminal Rules.
IX.
A presentence investigation and report should be made in every case where incarceration for one year or more is a possible disposition, where the defendant is less than 21 years old, or where the defendant is a first offender. ABA Standards Relating to Probation, § 2.1(b); Idaho Judge’s Sentencing Manual, § 5.2-1.
Id. at 9-10.
The same brief also states:
Again Judge Hargraves declined to order a presentence report over the objection of defendant’s counsel and in the face of the following guidance from the Idaho Judge’s Sentencing Manual at § 5.2-12:
The primary purpose of the presentence report is to assist the court in individualizing a rational sentence for the defendant. As one authority has stated:
‘No single instrument in our hands so neatly typifies the modern correctional philosophy as does the presentence report. Its only reason for being is to depict the intimate dynamics of one particular individual offender and to enable the court to dispose of his case with a tailor-made plan that is corrective in intent, whereas without such knowledge the disposition can only be punitive.’ KEVE, The Professional Character of the Presentence Report, Probation and Parole, 81 (R. Carter & L. Wilkins eds., 1970) (emphasis added).
Id. at 16.
. The Idaho Judge’s Sentencing Manual, § 5.1, provides: ‘‘After the determination of guilt it is essential that the court receive adequate information about the defendant before handing down the sentence. Individualizing sentences is impossible without such information.”
. The court’s dispensing with a presentence report is explained by the prosecutor’s contemporaneous statement:
For the record, Your Honor, I would point the Court to State versus Whitman at 96 Idaho 489 and State versus Gowin at 97 Idaho 146 in support of the Court’s decision not to order a pre-sentence investigation in this case when the Court does not consider probation an option.
Tr., at 373. The prosecutor, through no fault of his own, inadvertently was misleading the court as to the state of the law. Subsequent to the Whitman and Gowin decisions cited by the prosecutor, effective as of January 1, 1976, Idaho Rules of Criminal Procedure provide that if a PSR is not ordered, the record must establish why it was not. The Rules clearly superseded the case law rule of Whitman and Gowin.
In State v. Gowin, 97 Idaho 146, 147, 540 P.2d 808, 809 (1975), the Court’s opinion stated:
We recognize that a presentence report is only mandatory in the event that a trial court is considering a defendant for probation (I.C. § 20-220, State v. Rolfe, 92 Idaho 467, 444 P.2d 428 (1968); State v. McCollum, 77 Idaho 489, 295 P.2d 259 (1959)). We have held that a presentence report is not necessarily a requirement for the sentencing of a convicted felon. State v. Whitman, 96 Idaho 489, 531 P.2d 579 (1975).
This language, however, must be read in context. Indeed, the failure to order a PSR when the defendant is being considered for probation is per se error. I.C. § 20-220. The converse is not true. Simply because probation is not an option in a particular case does not mean a sentencing judge may dispense with the PSR. As discussed more fully infra, a trial court may forego a PSR only where (a) the record affirmatively establishes a valid reason therefor, and (b) there is sufficient information from independent sources to enable the sentencing court to *395fashion an appropriate sentence. In State v. Roderick, 97 Idaho 82, 540 P.2d 267 (1975), for example, the lack of a PSR was not grounds for reversal because the sentencing judge had adequate information before him to fashion an appropriate sentence, namely, a psychiatric evaluation and reports.
. Justice Bakes in dissent makes the bold — and unsupported — statement that "the Court of Appeals in this case acknowledged that the trial judge dispensed with the PSR in the exercise of sound judicial discretion.” Post at 397, 775 P.2d at 1239. The Court of Appeals decision begins on page 92 of volume 114 of the Idaho Reports (and page 828 of volume 753 of the Pacific Reporter (2d)). The interested reader will readily perceive that the Court of Appeals opinion makes no mention of a PSR and did not enter into any discussion pertaining to the trial court’s discretion in dispensing with the requirement of a PSR.
. Both of Power’s offenses were committed in the Second Judicial District, the first in Clear-water County on June 24, 1976, and the second in Nez Perce County on December 17, 1976. The sentences were imposed by the same judge.
. Justice Bakes in dissent makes the statement that ”[a]t the sentencing hearing Judge Hargraves knew, pursuant to his in camera discussions with counsel, that he was already in possession of all pertinent information and that a presentence report would not shed any additional light or expose any new evidence." Post at 398, 775 P.2d at 1240 (emphasis added). The record does not contain any such discussion.
Furthermore, even were Justice Bakes correct, it would have been impossible for Judge Hargraves to “know" that "he was already in possession of all pertinent information" without the benefit of a presentence investigation and report.
By contrast. Judge Transtrum in the companion case, State v. Griffith, 114 Idaho 95, 753 P.2d 831 (1988), did require a presentence report, and obtained from it much of the information which guided his sentencing decision. The report showed that Griffith "had a long history of incorrigible antisocial behavior; Griffith had previously been committed to a youth correction facility and had refused to cooperate in a rehabilitation counseling program; he has a bad temper and is unable to deal with authority; he was a drug user; he has no home and primarily lived in the streets. While incarcerated awaiting his trial in the instant matter, Griffith exhibited antisocial behavior and was involved in fights at the jail." 114 Idaho at 96, 753 P.2d at 832.
Moreover, we cannot in good conscience overlook the additional insight which we gain in this tragic affair by considering the remarks of the prosecuting attorney at Griffith’s sentencing hearing. In addressing Judge Transtrum concerning Griffith's complicity, the prosecutor stated that one of the witnesses attributed to Jerry Griffith the threat to Robert Thompson, ‘Tm going to kill you for messing with my friend." Tr. of Griffith Sentencing, p. 34. Speaking of Romero’s complicity, the prosecutor stated, "The one thing that you can say about Miguel Romero and it was forcibly argued to the jury, was that he had some element of provocation in the initial part of this incident, Miguel Romero was struck by Bob Thompson as Bob Thompson defended himself. He had a swollen eye and was bleeding.”
*396Whereas Romero had no previous criminal record, the prosecuting attorney advised Judge Transtrum as to even more in Griffith’s presentence report than the Court of Appeals set out in its opinion, "He’s got a long criminal record, going down and counting the various citations or charges that are identified just in the presentence investigation there are nearly twenty of those. Many of which are felony type offenses. According to the pre-sentence investigation he admits to others. The institutions that have dealt with him used terms such as explosive, impulsive, resistive, hostile, disruptive, argumentive and defiant to describe him. We can add one more, deadly____ When you look at the pre-sentence investigation it calls for his version of what occurred, what does he do. He essentially dissolves himself of responsibility and says it was Jose that was really out there, Jose and Miguel were the ones that were involved in the beating death of Robert Thompson. He didn’t make that statement previously. Police records indicated he never asserted that as a defense. In the waning moments before his sentencing then he tries to relieve himself of responsibility. Your Honor, he is a threat to society. As a younger person living in his home the investigative report indicates that he fought with his brothers. When he went to school he fought with his classmates. The report even tells about one incident where he was involved in some stealing or at least accused of stealing something. And, he chased after those that accused him and when he caught them he knocked them down and kicked them in the face.”
We also note that the district judge, in addition to not obtaining the information as to Romero’s previous history, did not take into account to at least some extent the fact that Mr. Thompson had been drinking, as also had Miguel Romero. To be certain, that is not an excuse for the homicide, but it is a factor. It is also a factor not given any mention in the opinion of the Court of Appeal. Yet Romero’s counsel in his brief, at page 4, pointed out that Mr. Thompson “had a blood alcohol concentration of .10, an alcohol level at which driving a motor vehicle under Idaho law is prohibited.”
The Court of Appeals did, however, correctly note that, although Romero "had been drinking for a prolonged period of time prior to the homicide, Romero had been talking with a girl when the confrontation began between Griffith and Thompson. Romero then chose to become involved in the fight and the brutal result.” 114 Idaho at 94, 753 P.2d at 830. This, of course, dovetails with the prosecuting attorney’s statements at the sentencing of Griffith, which were to the effect that Thompson’s initial blow dealt to Romero caused Romero’s involvement in a fight where he, Romero, was not the aggressor, but more apparently stepped forward to defend his companion, Griffith, and perhaps bring about an avoidance of any fight. The record is silent as to any propensity for previous fighting on the part of Romero, which is all the more reason for not excusing noncompliance with the rule requiring presentence reports. As appellant’s brief at page 4, citing to the transcript at pages 10, 230, and 334, asserts "only after a period of time did Miguel Romero exit the vehicle he was entering and walk over to Mr. Griffith and Mr. Thompson in an effort to stop the trouble that was brewing. (Tr., p. 10, LL. 15-17, Tr., p. 334, LL. 17-18, Tr., p. 230, LL. 13-15).” Appellant’s brief, at page 15, also adds that Judge Hargraves gave no consideration to five recommendations set forth in the Idaho Judge’s Sentencing Manual:
A. Previous good character should be considered in fixing punishment. (Section 2.2-1 of the Manual.)
B. Defendant should not be penalized for obtaining an acquittal on the charge of murder at jury trial. (Section 4.2-1).
C. The court should have adequate information about the defendant before sentencing. (Section 5.1-1 of the Manual.)
D. Presentence report should be ordered on every case where the defendant is a first offender OR under the age of 21. (Section 5.2-1 of the Manual.)
E. A sentence, only punitive in nature, is generally not advised. (Section 5.1-12 of the Manual).
