OPINION OF THE COURT
Appellant, Juan Perdomo, was convicted on cocaine possession charges in the District Court of the Virgin Islands. He appeals the denial of his motion for a judgment of acquittal or, in the alternative, a new trial. He asserts that his Fifth Amendment right to due process as set forth in
Brady v. Maryland,
I. Background
On October 17, 1989, Juan Perdomo was arrested in St. Thomas by Narcotics Strike Force officers and charged in connection with cocaine that he was alleged to have sold, approximately one month earlier, to a paid govеrnment informant, Hector Soto. At trial Soto, recounted the facts of the drug transaction and established that Per-domo had sold him “an eighth” (2V2 to 3V2 grams) of cocaine for $225. (App. at 121, 146). It was also established by other testimony that the transaction occurred in the area between “Smitty’s” Bar and Perdo-mo’s apartment building which is approximately 397 feet from the Evelyn Marcelli Elementary School. (App. at 126-29). On November 29, 1989, the jury found Perdo-mo guilty of three offenses as charged: possession of cocaine with intent to distribute in violation of 21 U.S.C. § 841(a)(1); distribution of cocaine in violation of 21 U.S.C. § 841(a)(1); and distribution of cocaine within 1000 feet of a school in violation of 21 U.S.C. § 845a(a).
Prior to trial, defense counsel submitted two written requests for any information relating to the criminal background of any prosecution witnesses. The prosecution responded that its key witness, the government informant Hector Soto, did
not
have a criminal record. (App. at 23). On the day following the return of the jury verdict, it

сame to light that Soto had a prior arrest and conviction record.
2
(App. at 14-15). Following the discovery that a criminal record existed, appellant filed a motion for a judgment of acquittal or, in the alternative, for a new trial on December 20, 1989. He argued that the prosecutor’s failure to disclose this information denied him his Fifth Amendment right to due process of law as guaranteed by
Brady v. Maryland,
II. Discussion
We turn now to review appellant’s argument that the trial court abused its discretion when it denied the motion for a new trial. Ordinarily we review a district court’s ruling on a motion for new trial on the basis of newly discovered evidence for abuse of discretion.
See e.g., Government of Virgin Islands v. Lima,
Appellant argues that the prosecution’s failure to provide defendant with information regarding the gоvernment informant’s
*970
prior criminal record constituted a violation of his right to due process under
Brady v. Maryland. Brady
provides that the suppression by the prosecution of evidence favorable to an accused, upon request by the defense, violates due process where the evidence is material either to guilt or to punishment, irrespective of the good faith or bad faith of the prosecution.
Brady,
A valid
Brady
complaint contains three elements: (1) the prosecution must suppress or withhold evidence, (2) which is favorable, and (3) material to the defense.
Moore v. Illinois,
A. Suppression of Evidence
Wе agree with the appellant that the prosecution’s failure to conduct a search of local Virgin Islands records to verify Soto’s criminal background meets the first element of a valid
Brady
complaint. It is well accepted that a prosecutor’s lack of knowledge does not render information unknown for
Brady
purposes. The Fifth Circuit has spoken the most often on this issue and has declined to excuse non-disclosure in instances where the prosecution has not sought out information readily available to it.
See United States v. Auten,
We agree with and adopt the reasoning of the Fifth Circuit. In the instant case, the prоsecutor’s argument that he did not have any knowledge of Hector Soto's criminal history is without merit. The prosecutor was obliged to produce information regarding Soto’s background because such information was available to him. In view of the fact that local Virgin Islands arrests and convictions are not recorded in the NCIC database, {see Perdomo Br. at 10) it is apparent to this court that the computer search was merely a token effort. Such an ineffectual attempt to verify a key pros *971 ecution witness’ criminal history amounted to conduct unworthy of the United States Attorney’s Office.
The following statement made by the district court judge during the sentencing hearing indicates that the court may have been under the impression that local records of crimes committed in the Virgin Islands are not readily available to the United States Attorneys Office:
THE COURT: If an NCIC check does not demonstrate there was a prior criminal conviction, then let the Third Circuit say that U.S. Attorneys and [the] U.S. Attorney’s office has to do more, they have to go through the sewage of San Juan and sewage of St. Thomas to see if there are some other files there. I’m not going to require that. (App. at 31).
We view the U.S. Attorney’s obligation somewhat differently than did the district court.
Auten
also stands for the proposition that non-disclosure is inexcusable where the prosecution has not sought out information readily available to it.
Id. Au-ten
and other cases indicate that the availability of information is not measured in terms of whether the information is easy or difficult to obtain but by whether the information is in the possession of some arm of the state. For example, in
United States v. Deutsch,
B. Favorable and Material Evidence
The second and third elements of a valid
Brady
complaint are that the information must have been favorable and material to thе defense.
Moore v. Illinois,
We also conclude that the evidence wаs material to the defense.
See Landano v. Rafferty,
Appellant has presented a compelling argument that the withheld information was material. Had the evidence been disclosed, the result of the proceeding might have been different. Soto appears to have had several contaсts with the criminal justice system. He has had, at least, two prior convictions and has been subjected to a *972 psychiatric exam. (App. at 221-227). Such information would have been critical in presenting the witness’ mental state, demeanor and behavior to the jury, and in questioning the witness’ credibility. In the instant case, defense counsel had the rare opportunity of being able to proffer, on appeal, a case that demonstrates exactly how the information might have been utilizеd in Perdomo’s defense. In a case arising out of an unrelated incident, but with a factual setting quite similar to the case at hand, Jose Rosario was acquitted of charges arising from another Narcotics Strike Force operation that involved the same Hector Soto. At Mr. Rosario’s trial, Soto testified as the key prosecution witness. The significant difference in the Rosario case was that, this time, the defense was provided with Soto's criminal history. Our review of the excerpts from the Rosario trial transcript reaffirms our judgment that the information concerning Soto’s criminal background would have contributed significantly to the outcome in Perdo-mo’s trial. Seldom have appellate judges seen such persuasive evidence that the availability of information on a prior conviction could have made a difference. We emphasize, however, that we simply find the information from the Rosario trial persuasive. We do not mean to suggest that in order to establish that undisclosed information is material, an appellant must offer proof of how the information was actually utilized in a subsequent trial. The inquiry for the court is simply whether there is a reasonable probability that the outcome of the trial would have been different. We find that a strong probability exists here.
The district court did not apply the correct standard for measuring materiality at the sentencing hearing. The court reasoned that the undisclosed information was not material because the jury had ample opportunity to evaluate Soto’s credibility due to other damaging testimony that had been elicited concerning the government payments to Soto and his prior drug usage. (App. at 27). Whether or not the jury has had an opportunity to consider other impeachment evidence is not the correct standard for determining materiality of undisclosed information. It is well-established that “impeachment evidence as well as exсulpatory evidence falls within the
Brady
rule.”
Bagley,
[i]f the standard applied to the usual motion for a new trial based on newly discovered evidence were the same when the evidence was in the State’s possession as when it was found in a neutral source, there would be no special significance to the prosecutor’s obligation to serve the cause of justice. Bagley,105 S.Ct. at 3383 .
The question is, therefore, whether the testimony that the defense would have been able to elicit would have been different had counsel known of Soto’s criminal record beforehand. In
Bagley,
the Supreme Court found that therе was a significant likelihood that the prosecutor’s negative response to the motion for discovery misleadingly induced defense counsel to believe that the two key witnesses could not be impeached on the basis of bias or interest arising from inducements offered by the Government.
Bagley,
C. Alleged Defense Knowledge of Undisclosed Information
The district court decided, not оnly that the prosecutor had not committed a
Brady
violation, but, also that defense counsel, a member of the Office of the Public Defender, was charged with the knowledge of Soto’s criminal record because a
different
person in the Public Defender’s office had represented Soto on an arrest that had resulted in a conviction. (App. at 29, 31). The court cited no authority in support of this holding. It is true that
Brady
does not oblige the government to provide defendants with evidence that they could obtain from other sources by exercising reasonable diligence.
United States v. McKenzie,
D. Evidentiary Hearing
Although appellant has made a very persuasive showing that a
Brady
violation did occur, we will nevertheless remand for an evidentiary hearing. We think that there аre several factual questions that should be determined before the issue can finally be resolved. This court has previously recognized that “where a factual question is raised as to whether a
Brady
violation occurred, the defendant is ‘entitled to have it determined by the district court in a hearing appropriate to the factual inquiry.’ ”
Gov’t of Virgin Islands v. Martinez,
[wjhere the submission of written affidavits raises genuine issues of material fact and where, as here, the Brady claims are neither frivolous nor palpably incredible, an evidentiary hearing should be conducted. Id. (quoting United States v. Dansker,565 F.2d 1262 (3d Cir.1977)).
In the case at hand, the district court’s consideration of the motion for a new trial during the sentencing hearing did not rise to the level of an evidentiary hearing that is required when a credible Brady claim has been raised. Certain pieces of key information were not before the district court or were not adequately considered at *974 the time of hearing. For example, Soto’s complete criminal record was not considered because the criminal history had not been compiled at the time that the hearing was conducted; appellant has raised questions as to the complicity of the Narcotics Strike Force agents in a possible cover-up of Soto’s criminal background; the effect of the undisclosed information on the outcome at trial was never actually considered; and appellant asserts that there is no evidence, beyond the prosecution’s statements at the sentencing hearing, as to whether an NCIC search was, in fact, actually conducted. We agree with appellant that an evidentiary hearing is necessary to resolve these unanswered questions. Once these questions are resolved, the court will be able to consider the proper measures to be taken to remedy the violation of Perdomo’s right to due process of law including the award of a new trial or other appropriate relief.
III. Conclusion
On the arguments before us, we conclude that the appellant has presented an undisputable argument that a Brady violation occurred. Accordingly, the judgment of the trial court denying a motion for a new trial and denying the motion for a judgment of acquittal will be vacated and the case remanded for further proceedings in accordance with this opinion.
Notes
. We, of course, recognize that there is a more rigid standard for the granting of a judgment of acquittal,
see United States v. Coleman,
.The exact way in which this information was discovered is unclear. At the sentencing hearing, the government alleged that the information first came to light as a result of a records search by two members of the Public Defender’s Office in preparation for another case. While searching their files, the public defenders found that their office had represented the informant in an earlier case that resulted in a conviction for burglary. (Govt.Br. at 12 citing A-24, A-29).
MR. HARRIS: * * * * The way that it came to light and what defense counsel is not telling to the court is that it came to light because Mr. McKelvin at the Public Defender’s Office knew about it and asked Attorney Peter Mabe of my office, isn’t this the guy that was convicted over in St. Croix, and upon that information being given with that specific point of reference, an inquiry was made and it was determined [it was] in fact the same Hector Soto.
(App. at 24). Appellant, on the other hand, argued that Mr. McKelvin was informed by an Assistant United States Attorney, Mr. Mabe, about the informant’s record.
. At the time of the hearing all of the facts regarding Mr. Soto’s criminal background had not been discovered. Subsequent to the sentencing, further investigation revealed that Soto had been arrested five times and had been convicted of burglary and cruelty to animals. As a result of that conviction, he was ordered to have рsychiatric evaluation and treatment. (Perdo-mo Br. at 15).
. The instant case is a tragic example of justice delayed. Perdomo was in custody from April 11, 1990 to November 5, 1990. By the time that his appeal was argued before this court, on December 5, 1990, he had already served his sentence and been released from custody. The appeal is, of course, not moot because Perdomo has a conviction of record and is still subject to up to six years of supervised release.
. The Office of the Public Defender represented Hector Soto in 1979. (Perdomo Br. at 11).
