On May 8, 2006, a jury convicted appellant Kenneth Millard of possession of marijuana, see D.C.Code § 48-904.01(d); possession of cocaine, see id.; carrying a pistol without a license (“CPWL”), see D.C.Code § 22-4504(a); possession of an unregistered firearm (“UF”), see D.C.Code § 7-2502.01; and unlawful possession of ammunition (“UA”), see D.C.Code § 7-2506.01(3). By order dated June 5, 2008, we granted appellant’s unopposed motion to vacate both of his drug possession convictions on the ground that the trial court’s admission of a Drug Enforcement Administration (“DEA”) substance analysis report (a so-called “DEA-7 report”) without testimony by the authoring chemist violated the Sixth Amendment Confrontation Clause and was not harmless error. 1 We now vacate appellant’s weapon convictions as well because we believe there is a reasonable possibility that admission of the DEA-7 report contributed to the jury’s guilty verdict on those charges.
I.
In summary, the evidence at trial was as follows. Metropolitan Police Department (MPD) Officer Howard Anderson testified that, shortly before 8 p.m. on February 9, 2005, he and Officers Marc Wilkins and Mark Harrison, all wearing police vests, were parked in the 2700 block of Jasper Road, S.E. in their unmarked police vehi- *157 ele. 2 The vehicle was at the bottom of a dirt path or “cut” that ran down a steep, wooded hill to the roadway. Appellant Millard “popped out of the woods” and ran into the left front quarter panel of the officers’ vehicle. After bouncing off the vehicle and falling, appellant grabbed his right waist area with his right hand as he rose to his feet. Perceiving appellant’s grabbing motion as an indication that appellant had a gun, Officer Anderson exited the car and began chasing appellant down the sidewalk. When they had run just a few feet away from the car, Officer Anderson tried to hit appellant’s shoulder, but appellant jerked away and again grabbed his right waist area. Officer Anderson then slapped appellant’s right elbow and a handgun “flew out” from appellant’s waistband. Appellant reversed direction and, as he was passing the police vehicle again, Officer Harrison emerged and helped Officer Anderson tackle and handcuff appellant. Besides appellant, police detained two other individuals who were in the vicinity that night. Officer Anderson also acknowledged that, in his Gerstein affidavit, he wrote that there were other individuals who ran through a “cut” in the area that night. 3
Officer Harrison substantially corroborated Anderson’s testimony. Although he did not see a gun fly out from appellant’s person, he recalled hearing the “clang” of a metallic object hitting the sidewalk when Officer Anderson was struggling with appellant. While searching appellant incident to his arrest, Officer Harrison found in the right front pocket of the jumpsuit that appellant was wearing an envelope containing cash and ten zip-lock bags containing a “greenish weed substance” and a “white chunk-like substance.” The DEA-7 report that the government offered into evidence and that was admitted over defense objections identified the “greenish weed substance” as marijuana and the “white chunk-like substance” as cocaine.
Officer Matthew Nickerson testified that he recovered a loaded Colt .22 semi-automatic handgun from the sidewalk on Jasper Road. An MPD fingerprint expert testified that the analysis of latent fingerprints recovered from the gun was inconclusive. Police also recovered a second handgun from a dumpster between Jasper Road and Robinson Place. The government’s evidence also included a Certificate of No Record of License to Carry a Pistol, and a Certificate of No Registration of a Firearm. Defense counsel objected to these exhibits on the basis of Crawford.
The defense called Investigator Adam Choka, who testified that he visited Jasper Road and located the three sites where (according to the defense’s interpretation of the government evidence) MPD officers saw appellant emerge from the woods, effectuated the arrest, and recovered the Colt .22 handgun. Referring to photographs of the area, Investigator Choka testified that, relative to the point where appellant ran out of the woods above Jasper Road, the location from which police *158 retrieved the gun was several feet in the opposite direction from the place where police tackled appellant. Investigator Choka further testified that the only-street-lamps on Jasper Road are across the street from the sidewalk bordering the woods, and that the sidewalk itself (where police found the Colt .22 handgun) was unlit.
Defense counsel sought to call Officer Mark Harrison back to the stand to testify that, on the day after the arrest, MPD officers searched appellant’s house pursuant to a warrant for drugs and drug paraphernalia, but found nothing incriminating. The trial judge (the Honorable Lynn Lei-bovitz) precluded the proffered testimony as irrelevant.
II.
Appellant argues that the erroneous admission of the DEA-7 report tainted the entire trial, entitling him to reversal not only of his drug-possession convictions, but also of his weapon convictions. As appellant emphasizes, where constitutional error has occurred at trial, we may affirm a judgment of conviction only if the error was “harmless beyond a reasonable doubt” as to the conviction.
Chapman v. California,
We conclude that there is a reasonable possibility that admission of the DEA drug analysis report did contribute to the guilty verdict on the weapon charges. During closing arguments, defense counsel’s remarks focused exclusively on the evidence related to those charges. In rebuttal, the prosecutor urged the jury to reject the defense theory that there was a merely coincidental relationship between appellant’s possession of drugs when he ran through the cut toward Jasper Road, and the gun found on the sidewalk along Jasper Road. Telling the jury that “the defendant is not, as the defense seems to want you to believe, the unluckiest person in the world,” the prosecutor mocked the defense suggestion that appellant “just happened to be on Jasper Road-with cocaine and marijuana in his pocket and a gun was lying there.” Thus, the prosecution invited jurors to draw a connection between the drugs' that appellant was carrying (which the defense did not deny during closing argument) and the Colt .22 handgun found in the vicinity of appellant’s arrest. In this context, the DEA-7 report confirming that the weed substance and white “chunk-like” substance that police found on appellant actually were marijuana and cocaine could well have helped persuade the jury that appellant had been carrying the loaded gun that police recovered.
Further, we cannot say that the government’s evidence against appellant as to the weapon charges was overwhelming. Officer Harrison heard a metallic “clang” but never saw appellant with a gun. Officer Anderson testified to seeing a gun fly out of appellant’s waistband, but the defense challenged the accuracy and credibility of his testimony on several grounds. The incident took place on the unlit side of *159 Jasper Road around 8 p.m. on a February night, when it would have been dark outside, making clear observation more difficult. Defense counsel argued to the jury that Officer Anderson’s general credibility was undermined by his “reluctan[ce]” to “admit that it would be nighttime.” 4 Defense counsel also emphasized that a photograph entered into evidence showed that on the night of his arrest, appellant was wearing coveralls, an article of clothing on which “[t]here is no waistband and there is no way a gun pops out of that waistband.” The latent fingerprints lifted from the gun that police recovered could not be matched to anyone, and (the defense argued, on the basis of Investigator Choka’s testimony) the gun was found some distance from where it would likely have fallen if it had “flown” out of appellant’s possession at the location where Officer Anderson slapped appellant’s arm. Both Officers Anderson and Harrison testified that appellant was holding his waistband area after he got up from falling and continued running, but that action was not inconsistent with the possibility that appellant injured himself when he ran into the police vehicle and fell to the ground. Further, the police officers’ testimony confirmed that other individuals scattered at the sight of police and ran through a “cut” toward Jasper Road that same evening, that a second gun was recovered nearby, and that two other individuals were arrested in the vicinity the same evening.
Of course, to prove its case, the government was “not required to negate every possible inference of [appellant’s] innocence,”
Coleman v. United States,
Because there is a reasonable possibility that the erroneously-admitted DEA-7 report contributed to the verdict on the weapon charges and because the evidence supporting those charges was not overwhelming, we vacate appellant’s CPWL, UF and UA convictions.
III.
We turn to appellant’s remaining arguments in the event that they arise on (possible) retrial.
6
First, we analyze appellant’s argument that, under the Supreme Court’s holdings in
Crawford
and in
Davis v. Washington,
In
Crawford,
the Supreme Court held that the admission of hearsay evidence against a criminal defendant without affording the defendant an opportunity to cross-examine the declarant violates the Sixth Amendment Confrontation Clause if the hearsay is “testimonial.”
9
See Crawford,
Following the Supreme Court’s decision in
Crawford,
this court held in
Thomas
that the DEA-7 chemical analysis report at issue in the case was “core” testimonial evidence.
Many of the factors that led us to conclude in Thomas that DEA-7 reports are testimonial weigh in favor of a similar conclusion about the CNRs in issue here. However, the CNRs are not entirely analogous to the DEA-7 report at issue in Thomas, and we do not believe that Thomas, or Crawford, requires us to hold that the CNRs are testimonial.
Like the DEA-7 report at issue in
Thomas,
the CNRs are formal and solemn documents that were prepared at the instance of and in response to an inquiry by law enforcement officials and were obtained expressly for use in prosecuting appellant.
Thomas
did not hold, however, that this subset of the factors it discussed is dispositive of whether a statement is testimonial.
13
And, in contrast to DEA-7
*162
reports, we think it is appropriate to regard the CNRs
not
as “substitutes for live testimony,” which was how we characterized the DEA-7 report at issue in
Thomas.
Notably, in the immigration context, where the government uses the absence of any iecord that an alien has been lawfully re-admitted to the United States as evidence supporting criminal prosecution for violation of an order of deportation,
16
every court to rule on the issue has concluded that CNRs are non-testimonial.
See United States v. Burgos,
*164 IV.
The original indictment charged appellant with possession of cocaine with intent to distribute while armed (“PWIDWA”). During trial, Judge Leibovitz precluded the government, as a discovery-sanction, from presenting certain expert testimony. Because the expert testimony was essential to the government’s case on the PWIDWA charge, the court reduced the charge to one of simple possession and dismissed the PWIDWA charge. Earlier, however, before the PWIDWA charge was dismissed, the court had ruled that the defense would not be permitted, in an effort to counter the intent-to-distribute charge, to elicit testimony that police had executed a search warrant at appellant’s home on the day after appellant’s arrest and found no evidence of drugs or drug paraphernalia. Judge Leibovitz reasoned that whether or not appellant had such items in his home the next day was not probative of his intent to distribute on the day of his arrest, and thus not relevant. After the court dismissed the PWIDWA charge, the defense renewed its request to present evidence about the fruits of the search, proffering that the testimony would be that police “did not find anything associated with guns or drugs.” Judge Leibovitz declined to change her ruling. *165 Appellant now argues that the ruling was in error as to the weapon and drug possession charges. We address this issue because, like the CNR/Confrontation Clause issue, it could arise again if the government seeks to retry appellant.
“Relevant evidence is that which tends to make the existence or nonexistence of a fact more or less probable than would be the case without that evidence.”
Brown v. United States,
*166 Conclusion
For the foregoing reasons, we vacate appellant’s convictions. In the event the government retries appellant, the trial court is not precluded from admitting into evidence, without testimony by the individual who searched the MPD’s firearm licen-sure and registration records, certificates of no record that appellant possessed a firearm registration certificate or a license to carry a firearm on February 9, 2005. The court may also exclude evidence that police found no gun or drug paraphernalia when they searched appellant’s home on February 10, 2005.
So ordered.
Notes
. At trial, the defense objected to the admission of the DEA-7 report on the basis of
Crawford v. Washington,
. On cross-examination, Officer Anderson testified that he did not recall whether it was dark outside.
. Officer Anderson testified on re-direct, however, that "nobody else ran through that cut” (presumably referring to the cut through which appellant ran).
Officer Leroy Rollins testified that he was involved in the same police operation as Officers Anderson and Harrison on the night in question, but was waiting on Robinson Place, the street that runs along the hill above Jasper Road. He observed several individuals gathered near a parking lot and, when he pulled up in his (unmarked) car, the individuals scattered. Two people ran by him, one of whom fled behind a nearby building and one of whom went into the woods towards Jasper Road.
. See note 2 supra.
.
See Winters v. United States,
. We read appellant’s “Unopposed Motion to Vacate [Drug] Convictions and Remand for Retrial” to indicate that appellant was scheduled to complete serving his jail time on the weapon convictions on October 13, 2008. Because it appears that by now appellant has completed serving that time, we surmise that "retrial is doubtful.”
Saltys v. Adams,
. The Certificate of No Record of a License to Carry a Pistol reads:
This is to certify that the records of the Metropolitan Police Department relating to the issuance of licenses to carry a pistol are in my custody and control, pursuant to the above-quoted directive of the Chief of Police of which I certify the foregoing is a true and accurate copy, and state that a diligent search has been made of those records for information concerning the following described person: Kenneth Millard. According to the records of this department the above-named person did not on 2/9/05 have a license to carry a pistol in the District of Columbia nor does he now have such a license.
. The Certificate of No Registration of Firearm reads:
This is to certify that the records of the Metropolitan Police Department relating to the issuance of Firearm Registration Certificates are in my custody and control pursuant to the above-quoted directive of the Chief of Police of which I certify the foregoing is a true and accurate copy, and state that a diligent search has been made of these records for information concerning the following described person: Kenneth Millard.... According to the records of this department, t he above-named person did not on 02-09-05 have a Firearms Registration Certificate issued or pending for the below-described firearm/ammunition ... Colt .22 lr Semi-Auto ... Serial Number PH48169 [and] .221r lOrounds.
. More specifically, the Court explained, "the Framers would not have allowed admission of testimonial statements of a witness who did not appear at trial unless he was unavailable to testify, and the defendant had had a prior opportunity for cross-examination.... The Sixth Amendment therefore incorporates those limitations.”
. The Court did not define the term “testimonial,” but did describe "[v]arious formulations of this core class of 'testimonial' statements” urged in the briefs of the
Crawford
petitioners and
amici
or set out in a concurrence to a prior opinion of the Court.
. As the Court later clarified in
Davis,
statements to police “are nontestimonial when made ... under circumstances objectively indicating that the primary purpose of the interrogation is to enable police assistance to meet an ongoing emergency [and] are testimonial when the circumstances objectively indicate ... that the primary purpose ... is to establish or prove past events potentially relevant to later criminal prosecution.”
Davis, supra,
. We relied on similar factors in subsequent opinions.
See, e.g., Roberts v. United States,
.Nor has the Supreme Court held that this subset of the "various formulations” it described in Crawford is dispositive of whether a hearsay statement is testimonial. See note 10, supra.
We note also that numerous federal and state courts have held that certificates of authenticity, which also are formal declarations often prepared for use at trial (to facilitate the admission of other documents) are non-testimonial.
See, e.g., United States v. Weiland,
. It might be argued that, similarly, a DEA-7 report is really just a substitute for bringing into the jury room the samples, litmus chemicals, and laboratory paraphernalia that the jury would need to discern for itself whether a substance is contraband. However, in that scenario, the jury would still need instruction from an expert about how to conduct the testing and read the test results-demonstrating that the DEA-7 report inevitably is a substitute for live testimony. By contrast, with a (non-testimonial, see note 13 supra) certificate authenticating the files brought into the jury room as the complete firearm registration and licensure files, a jury would need no more instruction to be able to sift through the files to discern whether the files contain a record of a certificate or license issued to defendant.
. See also 5 John Henry Wigmore, Evidence in Trials at Common Law § 1678(6)-(7) (James H. Chadbourn rev.l974)(explaining that the so-called "rule of completeness,” rather than the principle of confrontation, animated most common law courts’ exclusion of certificates of nonexistence of public records).
.
See, e.g., United States v. Cervantes-Flores,
.
But see People v. Niene,
. We recognize that one rationale underlying a number of the decisions we have cited above is that a CNR is, or is indistinguishable from, a business record (which
Crawford
specifically referred to as an example of a non-testimonial statement,
see
In concluding that the admission of CNRs without an opportunity for cross-examination of the declarant does not violate the Confrontation Clause, some courts also have questioned the value of cross-examination in this context.
See, e.g., Salinas-Valenciano,
That said, we cannot fail to mention a factor that applies, perhaps uniquely, to the CNRs at issue here. We would be ignoring reality—and behaving much like the denizens in
The Emperor’s New Clothes
— were we not to acknowledge that, at the time of the charged weapon offenses, "[t]he District of Columbia generally prohibited] the possession of handguns.”
