STATE of Louisiana
v.
James C. LOCKWOOD.
No. 82-KA-1674.
Supreme Court of Louisiana.
October 17, 1983.
*395 William J. Guste, Jr., Atty. Gen., Barbara Rutledge, Asst. Atty. Gen., John F. Rowley, Dist. Atty., Paul Katz, Abbott Reeves, Asst. Dist. Attys., for plaintiff-appellee.
William L. Crull, III, Dymond, Crull & Castaing, New Orleans, for defendant-appellant.
DIXON, Chief Justice.[*]
Defendant was arrested and charged with aggravated crime against nature, having been accused of engaging in oral-genital sex with two eleven year old boys. The defendant pleaded guilty to both counts, and a presentence investigation was ordered. Upon learning the contents of the presentence investigation report, defendant filed a motion to traverse presentence investigation and report and an application for supplemental presentence investigation, pointing out fourteen specific errors or omissions.
The trial court denied defendant's motion and application, denying defendant an opportunity to refute or explain materially false or invalid information contained in the PSI report and read by the court. The court then sentenced defendant to serve two years with the Department of Corrections. Defendant appealed and this court vacated the sentence and remanded for traverse of the investigation and resentencing in the light of the traverse hearing. State v. Lockwood, 399 So.2d 190 (La.1981).
The trial court held a hearing on the motion to traverse, and denied defendant's application for supplemental presentence investigation. That court then made its previous two year sentence executory and continued defendant on bond. Defendant then appealed to this court.
Defendant acknowledges that he has no constitutional or other right to demand a presentence investigation. That investigation is conducted at the option of the court. C.Cr.P. 875 A(1).[1] He contends correctly, however, that if a PSI is conducted, and a report compiled, he is entitled to a fair and accurate report.
*396 In State v. Parish, 429 So.2d 442, 444 (La.1983), we stated that "... the fundamental precepts of due process require that a criminal defendant be afforded an opportunity to rebut or explain prejudicial or erroneous information in a presentence report..." That decision is consistent with the line of cases following State v. Underwood, 353 So.2d 1013, 1018 (La.1978), where we concluded that the defendant was entitled to have his sentence set aside because the false or invalid data contained in the PSI, and to which the sentencing judge was exposed, might have contributed to the severity of the sentence.
In addition to sentencing by the trial court, defendant cites two other uses of the presentence investigation report: classification by the penal system in cases of incarceration and deliberations of the parole and pardon boards. Other potential readers of the PSI report are listed in C.Cr.P. 877[2] and R.S. 15:574.12.[3] An inaccurate PSI has lingering *397 consequences and cannot easily be corrected long after it has been written.
It is important that a defendant be afforded an opportunity to rebut or explain erroneous information in a presentence investigation report so that his sentence is not unfairly excessive. It is equally important that an inaccurate report be revised so that the defendant is not subsequently unfairly prejudiced by subsequent uses of the PSI report.
When making his presentence investigation, the probation officer "shall inquire into the circumstances attending the commission of the offense, the defendant's history of delinquency or criminality, his family situation and background, economic and employment status, education and personal habits." C.Cr.P. 875 A(1). The probation officer cannot make an accurate report of a defendant's family situation and background, or of his personal habits, without talking to the defendant or to someone who knows the defendant well. Casual conversations with neighbors who know the defendant only through the newspaper reports of his offense are not reliable investigative techniques.
The probation officer who prepared defendant's PSI report failed to meet or talk with the defendant; he obtained most of the information for the report from the offices of the district attorney and the sheriff, or from cryptic notes left by a coworker. He did not interview the victims or the parents of the victims; he did not keep any records of those to whom he talked. He admits that much of his report is based on unverified hearsay or on his own preconceived opinions and beliefs.
Even in those instances where the probation officer recommends incarceration rather than probation, it is his duty under law to "indicate specifically those resources available in the community which could provide needed assistance to the defendant should he be released on probation ..." C.Cr.P. 875 A(2). This probation officer did not indicate community resources that might assist the defendant. The entire report was prepared with little or no attention given to the truth of its contents, or to the thoroughness of the investigation.
At the hearing on the motion to traverse, the probation officer was unable to cite his sources, except generally to name persons with whom he frequently talked about criminal defendants. The state did not produce one witness to substantiate any of the contested information. The defendant produced witnesses who directly contradicted statements made in the report. It appears that the PSI report on Lockwood is significantly and substantially inaccurate and should not be used in sentencing, classification, parole or pardon deliberations, or for any other purpose.
The purpose of the PSI and report is so important to the defendant and to the integrity of the judicial system that it must be fair, not based solely on impression or opinion, but based on conclusions rationally derived from information from identifiable sources.
The probation officer should check the veracity of his sources, and maintain some record of his discussions, to enable a court to verify that the information in the PSI report is reliable.
The trial court on remand did not state his reasons for denying the defendant's application for supplemental PSI, or for making his previous sentence executory. We cannot conclude from the record that, when sentencing the defendant, the court considered the testimony of the defendant's witnesses at the hearing on the motion to traverse.
The defendant is entitled to a new presentence investigation and report, and is entitled to be resentenced, based on the findings of the new investigation, by a judge who has not been exposed to the existing inaccurate and prejudicial report.
The sentence is vacated and the case is remanded for a new presentence investigation and report, and for resentencing in accord with this decision.
BLANCHE, J., concurring in part and dissenting in part.
*398 BLANCHE, Justice (concurring in part and dissenting in part).
While this writer concurs that there would be a denial of due process to allow an inaccurate PSI to remain in defendant's criminal records, I dissent from the opinion's remand of the case to a different judge. There is no showing that the trial judge could not render a fair sentence despite his knowledge of the first inaccurate PSI. Rather, two years does not seem excessive despite the biased and inaccurate report.
The case should be remanded to the same trial judge to require the Department of Corrections to supplement the PSI based on the evidentiary hearing and to thus sentence the defendant in accordance with the law.
