The defendant, Tony T. Deberry, challenges his convictions in the Superior Court for first degree rape (11 Del.C. § 764), first degree kidnapping (11 Del.C. § 783A), and possession of a deadly weapon during the commission of a felony (11 Del.C. § 1447). He has been sentenced to life imprisonment.
Deberry first contends that reversible error occurred when the State did not produce or account for potentially exculpatory evidence. We agree and reverse since this deprived Deberry of evidence to which he was entitled under Superior Court Criminal Rule 16(b) and
Brady
v.
Maryland,
I.
A.
The alleged victim, Beverly, and Deberry were both employed by Delaware Park racetrack during the summer of 1980. The State’s evidence was that on August 14, 1980, Beverly, her boyfriend, Mark, and De-berry had been attending a party which began about 12:30 or 1:00 p.m. on the track premises. People were drinking all afternoon and taking drugs. As the party went on into the night, Mark became involved in several fights, and on one occasion Deberry helped break up an altercation. After-wards Deberry invited Beverly and Mark to his room to calm down from these incidents. There, they continued to drink and take drugs. According to Beverly, Deberry tried to persuade her to spend the night with him. Soon after Deberry’s proposition, Beverly went to another bunkhouse to sleep with two other men, one of whom Mark had fought earlier. Mark accompanied her but decided to sleep outside because of his earlier fight with one of the occupants.
Beverly claims she was awakened by De-berry shortly after falling asleep. She told him to leave, and he did so. Sometime later she was again awakened by Deberry, who was attempting to pull her pants off. This time Deberry put a knife to Beverly’s throat. When she saw the knife, she supposedly grabbed for it and cut several fingers.
Beverly and Deberry then went about one hundred yards from the bunkhouse to a spot behind a barn. He threatened to kill her if she screamed, and he ordered her to undress. After partially undressing, Deber-ry had intercourse with her. They spent about thirty minutes behind the barn when Deberry began to fear discovery. He ordered Beverly to dress and led her at knife point to a more secluded area outside the track enclosure. To reach this location, they had to pass a guard station, where a guard observed two people leave the track. When they reached the second spot, Deber-ry made Beverly undress, and for an hour or more they had intercourse.
The two then returned to the track complex. The guard at the gate asked for and examined their employee identification cards. When they separated, Deberry warned Beverly not to mention the incident. Returning to her boyfriend, Beverly woke him to take her to the hospital to have her hand treated (which later required sutures). On the way out of the track complex, she told him that Deberry had raped her. The police were called and arrived about ten minutes later. Beverly explained what happened and led them immediately to Deberry’s bunkhouse. An officer went inside and brought Deberry to the door. Beverly was sitting in a police car about 20-30 feet from Deberry, and the ear’s headlights were aimed toward the door in which Deberry stood. A policeman asked *748 her if Deberry was the assailant, and she answered without hesitation that he was.
Deberry’s version of the facts was that after accompanying Beverly and Mark to the bunkhouse where she wanted to sleep, both Deberry and Mark bedded down outside her door. However, the ground was damp, and after a few minutes he returned to his own bunkhouse where he promptly went to sleep. The next thing he knew was when he was awakened by the police. He has consistently denied any participation in the alleged attack on Beverly.

In a pre-trial discovery request, the defense asked for the following:
3. A list of all books, papers, documents or tangible objects in the possession of the State pursuant to its investigation of the above-captioned case.
******
5. All information and materials in the possession of the State which fall within the scope of Brady v. Maryland ... and its progeny as to the defendant in the above-captioned ease.
The State replied that there were no objects in its possession, and that there was no Brady material.
Immediately before the start of Deberry’s first trial (which resulted in a mistrial), the defense inquired about production of the clothes Deberry wore during the alleged attack. The clothing was of obvious relevance since the likelihood of Beverly’s blood being found on it was very strong. She and the defendant purportedly had intercourse in two places for IV2 hours or longer; she claimed to have been cut when Deberry awoke her; and the injury was severe enough to require stitches several hours later. Under such circumstances the defense argued that Deberry could not avoid getting Beverly’s blood on his clothes if he in fact was her assailant. Counsel asked the court to determine if the clothing was available, and he indicated that the defendant would seek dismissal of the charges if these items were not produced.
In response to the defense allegation that the presence or absence of blood on Deber-ry’s clothing was material to the case, the prosecutor stated that he was unaware of any blood found on Deberry’s clothes. The trial judge observed that if the presence of blood was at issue, testimony that there was no blood on the clothing would be an acceptable substitute for the actual clothing. However, the judge’s ultimate ruling went only to the scope of testimony about the injury on Beverly’s hand, rather than the potentially exculpatory effect of the absence of blood on Deberry’s clothes. 1 The prosecutor was also directed to determine if the clothing was available and to so advise the defense. The clothing, however, was not found.
At the second trial, one state police detective testified, consistent with his testimony at Deberry’s first trial, that a detective assigned to the evidence unit took Deberry’s clothing and the victim’s clothing. The evidence unit detective, however, testified that Deberry’s clothing had not been seized and had not been sent to the FBI for analysis. Furthermore, he did not know what had happened to those items. Deberry testified that the police took all of his clothing from his room. He never returned there, having been incarcerated since his arrest. Thus, he *749 states that the police have had full control over his personal effects since that night.
The forensic evidence introduced at trial consisted of results of blood and hair comparisons. From the victim’s jeans, a black head hair of Negroid origin was recovered. Though the majority of structural characteristics resembled those of Deberry’s hair, there were sufficient disparities to prevent the FBI analyst from reaching any conclusion as to its origin. . In the combings obtained from Deberry’s pubic region, a hair was found that was dissimilar to that of the victim, and no other hair was recovered. While there were blood and semen stains on Beverly’s clothes, results of blood typing tests were inconclusive. There was no evidence about blood on the knife allegedly used by Deberry in the attack. The doctor who examined the victim testified that there were no signs of forcible intercourse, but the absence of trauma would be consistent with either non-eonsensual or consensual intercourse.

Deberry contends that the State was required by
Brady v. Maryland,
In response, the State argues that the duty under
Brady
and
Agurs
attaches only when it actually possesses or has access to the requested material.
Boyer v. State,
Del.Supr.,
The parties have argued this case along the lines suggested by
Brady
and
Agurs,
i.e., was the evidence favorable to the defense, and was the evidence material? However, we view the issue differently. The question is not whether the clothing was subject to discovery by the defense, but what should be done when the State takes possession of exculpatory (or potentially exculpatory) evidence and then loses or destroys it before or in response to the defendant’s discovery request. Perhaps in a broad sense
Brady, Agurs,
and
Stokes v. State,
Del.Supr.,
Instead, claims of this type must be examined as follows:
1) would the requested material, if extant in the possession of the State at the time of the defense request, have been subject to disclosure under Criminal Rule 16 or Brady? 3
2) if so, did the government have a duty to preserve the material?
3) if there was a duty to preserve, was the duty breached, and what consequences should flow from a breach?

Superior Court Criminal Rule 16(b) allows a defendant “to inspect and copy or photograph designated books, papers, documents, tangible objects, buildings or places, copies or portions thereof which are within the possession, custody or control of the State....
”
In
State v. Winsett,
Del.Super.,
Here, Deberry first asked for a list of materials and objects that would have been subject to disclosure. We assume that Deberry intended to use this list to prepare a subsequent discovery request, specifying as required by Rule 16(b) the particular items he wished to inspect or copy.
See State v. Traenkner,
Del.Super.,
C.
The second step in our analysis — the State’s duty to retain discoverable evidence — is well settled: the failure of the government “to take adequate steps to preserve evidence may deny a defendant due process and thereby jeopardize otherwise viable convictions”.
E.g., Government of the Virgin Islands v. Testamark,
It is most consistent with the purposes of those safeguards to hold that the duty of disclosure attaches in some form once the Government has first gathered and taken possession of the evidence in question. Otherwise, disclosure might be avoided by destroying vital evidence before prosecution begins or before defendants hear of its existence .... Only if evidence is carefully preserved during the early stages of investigation will disclosure be possible later.
We fully endorse this view, and hold that the State’s duty to disclose evidence includes a duty to preserve it as well. The obligation to preserve evidence is rooted in the due process provisions of the four
*752
teenth amendment to the United States Constitution and the Delaware Constitution, article I, section 7. The duty of preservation extends not only to the Attorney General’s office, but all investigative agencies, local, county, and state.
Bryant,
D.
The last step in our analysis is whether the State has breached its duty to preserve evidence, and if so, what effect such breach has on this conviction. In making that analysis, we draw a balance between the nature of the State’s conduct and the degree of prejudice to the accused. The State must justify the conduct of the police or prosecutor, and the defendant must show how his defense was impaired by loss of the evidence. In general terms, the court should consider “(1) the degree of negligence or bad faith involved, (2) the importance of the lost evidence, and (3) the sufficiency of the other evidence adduced at the trial to sustain the conviction”.
United States v. Loud Hawk,
More specifically, when examining the conduct of the State,
the court should inquire whether the evidence was lost or destroyed while in [the State’s] custody, whether the [State] acted in disregard for the interests of the accused, whether [the State] was negligent in failing to adhere to established and reasonable standards of care for police and prosecutorial functions, and, if the acts were deliberate, whether they were taken in good faith or with reasonable justification .... It is relevant also to inquire whether the government attorneys prosecuting the case have participated in the events leading to loss or destruction of the evidence, for prosecu-torial action may bear upon existence of a motive to harm the accused.
Loud Hawk,
the centrality of the evidence to the case and its importance in establishing the elements of the crime or the motive or intent of the defendant; the probative value and reliability of the secondary or substitute evidence; the nature and prob *753 able weight of- factual inferences or other demonstrations and kinds of proof allegedly lost to the accused; [and] the probable effect on the jury from absence of the evidence....
Loud Hawk,
Having outlined the inquiry that a court should make, we find the record devoid of any explanations as to the loss of this evidence. Deberry says that the police removed all of his clothing from his room; one detective testified that another detective took the clothes; and the second detective denies doing so. In the usual situation, we would remand the case for additional findings of fact.
See Bryant,
Though the record contains a minimum of information about the loss of De-berry’s clothing, we think that the responsibility for the lost evidence must lie with the State. First, Deberry was an itinerant race track worker. His meager possessions were all located in his room, including the clothes he allegedly wore during the attack. When the police took him into custody he had no way of preserving or protecting this all important physical evidence. On the other hand the police were in an absolutely superior position to do so, and one officer has identified another detective as having taken possession of those items. Second, in a crime of this type, it is not unreasonable to anticipate that the apparel of both the victim and the alleged perpetrator would be crucial evidence of the defendant’s guilt or innocence. Certainly, the actions of the police reflect the importance of the clothing since they clearly obtained Beverly’s clothes, and the record supports the conclusion that they seized Deberry’s clothes as well. Having done so, the police had a duty to preserve such vital evidence. Thus, when physical evidence of this type is lost or otherwise becomes unavailable through some apparent default of the police, the State bears a heavy burden of overcoming the defendant’s claim of prejudice. A haphazard explanation of the loss is insufficient, since anything less than the fullest possible accounting could stymie the defendant’s efforts to show improper or inadequate handling of evidence and to obtain appropriate relief.
Though the track guard claimed to have checked an employee’s pass with Deberry’s name on it at the time Beverly claimed to have left and returned to the track complex, the only evidence linking Deberry to the actual rape was Beverly’s account. The physical and medical evidence was inconclusive at best. If the clothing did not contain Beverly’s hair, or blood from her serious hand wound, or semen stains, the absence of such evidence would support Deberry’s denial of having intercourse with her. Admittedly, Deberry’s disclaimer was less credible in light of the guard’s testimony, corroborating Beverly’s account of leaving and returning to the track, and the medical evidence that she had engaged in sexual intercourse, but that only underscores the potential importance of the clothing. The results of any scientific tests performed on the clothes were clearly important to either the prosecution or defense of the crime, and the weight of substitute evidence, in effect *754 only Deberry’s denial, might well have been less in the minds of the jurors than that of any scientific test. The degree of prejudice caused by the loss of the clothing is more than sufficient to justify relief, particularly considering the duty imposed on the police to obtain and preserve physical evidence clearly within its control at the scene of a crime or the site of an arrest.
The failure of the State to produce Deberry’s clothes upon request or to conduct scientific tests, as was done on the victim’s apparel, permits us to infer that any scientific evidence obtained from such items would have been favorable to Deber-ry. The State’s production of otherwise inconclusive scientific evidence, when presumably strong evidence was available (or would have been, if the evidence had been handled properly), implies that the strong evidence would have been adverse to the prosecution.
See Interstate Circuit, Inc. v. United States,
III.
Deberry also challenges the admission into evidence of his identification by Beverly. He contends that the on-site confrontation between them was unnecessarily suggestive and created a substantial likelihood of misidentification. This, according to him, led to an unreliable in-court identification by Beverly. The State responds that the confrontation was not unnecessarily suggestive or conducive to mistaken identification.
In this instance, the prompt on-site confrontation was not unnecessarily suggestive, being an “immediate product of the offense and defendant’s apprehension”.
Watson v. State,
Del.Supr.,
REVERSED AND REMANDED.
*755 ORDER ON CONSIDERATION OF THE STATE’S MOTION FOR REARGUMENT
This 16th day of February, 1983, the Court has before it the State’s Motion For Reargument, submitted to us on February 14, 1983. It now appears that following issuance of our opinion on January 27,1983, the State found the clothes seized at the time of defendant’s arrest. The State also admits that these items have been in its possession at all times relevant to these proceedings, despite the fact that it was twice ordered by the trial court to search for and produce them, and on each occasion the State represented to the trial court that they could not be found. Indeed, the State denied both here and in the Superior Court that it ever had such items. Even now it continues to base its arguments on that premise. After carefully considering the State’s position, we do not believe that this belated discovery of evidence, which the defendant has repeatedly sought at two separate trials, alters our conclusions. If anything, the circumstances which have now come to light only underscore the importance of and need for the rules we announced regarding the State’s handling of evidence in criminal matters.
Accordingly, the Motion For Reargument is DENIED.
Notes
. This appears from the following exchange between the trial judge and the deputy attorney general trying the case:
THE COURT: Well, let me just make this point: That if the clothing is itself not available, the State shouldn’t attempt to introduce any testimony that there was blood, unless notice is given to the defendant, and I can hear any further application.
MR. MIECZKOWSKI [Deputy Attorney General]: When you say blood on the clothing— THE COURT: Yes.
MR. MIECZKOWSKI: I don’t think we expect doing that. The only evidence we intend to introduce of the injury would be the victim’s treatment and the doctor who examined and treated that injury.
THE COURT: Well, I would ask you—
MR. MIECZKOWSKI: I’ll avoid any reference to it.
THE COURT: Yes.
. The State argued that the detective’s recollection about who had custody of the evidence might have been faulty since it was clear that the victim’s clothing had been taken by a hospital employee and not by the evidence unit detective. However, the detective’s statement that the evidence unit detective took the victim’s clothing can also be interpreted to mean *750 that the evidence officer took the clothing after the hospital staff took it from the victim. This latter interpretation is supported by the testimony of a nurse at the hospital: the victim’s clothing was bagged, labeled, and then given to a detective.
. Rule 16 provides in pertinent part:
(a) Defendant’s Statements; Reports of Examinations and Tests; Defendant’s Grand Jury Testimony. The defendant may serve upon the Attorney General a request to permit the defendant or someone acting in his behalf to inspect and copy or photograph any relevant (1) written or recorded statements or confessions made by the defendant, or a co-defendant (whether or not charged as a principal, accomplice or accessory in the same or in a separate proceeding), or copies thereof, and the substance of any oral statement which the State intends to offer in evidence at the trial made by the defendant whether before or after arrest in response to interrogation by any person then known to the defendant to be a state agent which are known by the Attorney General to be within the possession, custody or control of the State, (2) written reports of autopsies, ballistics tests, fingerprint analyses, handwriting analy-ses, blood, urine and breath tests, and written reports of physical or mental examination of the defendant or the alleged victim by a physician, dentist or psychologist made in connection with the particular case, or copies thereof, which are known by the Attorney General to be within the possession, custody or control of the State, and (3) recorded testimony of the defendant before a grand jury.
(b) Other Books, Papers, Documents or Tangible Objects. The defendant may serve upon the Attorney General a request to permit the defendant or someone acting on his behalf to inspect and copy or photograph designated books, papers, documents, tangible objects, buildings or places, copies or portions thereof which are within the possession, custody or control of the State, upon a showing that the items sought may be material to the preparation of his defense and that the request is reasonable. This subdivision does not authorize the discovery or inspection of reports, memoranda, or other internal State documents made by agents in connection with the investigation or prosecution of the case, except as provided in subdivision (a) of this rule, or of statements made by State witnesses or prospective State witnesses (other than the defendant or a co-defendant) to agents of the State.
. At the time of the Winsett decision, Rule 16 read:
Upon motion of a defendant at any time after the filing of the indictment or information, the court may order the Attorney General to permit the defendant to inspect and copy or photograph designated books, papers, documents, tangible objects, confessions or written statements obtained from or belonging to the defendant or a co-defendant or obtained from others by seizure or by process upon a showing that the items sought may be material to the preparation of his defense and that the request is reasonable. The order shall specify the time, place and manner of making the inspection and of taking the copies and photographs and may prescribe such terms and conditions as are just.
