Defendant-appellant Cruz Roberto Ramos-González (“Ramos”) appeals his conviction for possession with intent to distribute in excess of 500 grams of cocaine. See 21 U.S.C. §§ 841(a)(1), 841(b)(1)(B). Among other claims of error, Ramos contends that his Sixth Amendment right to confrontation was violated when the district court allowed a forensic chemist to testify regarding the results of a drug analysis that he did not conduct. Recent Confrontation Clause jurisprudence compels us to agree. For the reasons set forth below, we vacate the conviction and remand for a new trial consistent with this decision.
I. Background
In July 2002, while on routine traffic patrol in Caguas, Puerto Rico, Transit Police Officers Wanda Vélez-Mojica (“Vélez”) and Javier Reyes-Flores (“Reyes”) attempted to stop a pickup truck with unlawfully tinted windows. The driver refused to yield, and a chase ensued. Although the officers were able to forcibly stop the vehicle, the driver fled on foot and managed to elude capture. Upon closer inspection of the abandoned truck’s interior, Vélez identified two plastic-wrapped blocks of a substance that she believed to be drugs, and the blocks were taken to the Puerto Rico Transit Police Station in Caguas (“Caguas station”) for analysis.
At the Caguas station, an agent from the Drug and Narcotics Division, Juan Santana Rodriguez, conducted a field test of the blocks. Neither Vélez nor Reyes participated in the field test, and there is no evidence that it was observed by any other officer. The two blocks were subsequently transferred to the Puerto Rico Forensic Science Institute (“the Institute”), where they purportedly tested positive for cocaine.
The Institute chemist who analyzed the seized substance, José Borrero, was initially listed as a prosecution witness; however, due to mental illness and related treatment, he was unavailable to testify regarding his analysis. Thus, three days *3 before the trial commenced, the government amended its witness list to substitute Kelvin Morales-Colón (“Morales”), another chemist at the Institute, for Borrero. Despite the substitution, the witness description remained unchanged, identifying Morales as an expert who would testify “[biased on his specialized training and experience in the examination and analysis of controlled substances ... including the methodology used to examine the [drugs seized from the pickup], and the conclusions reached based on his expertise and examination of the substances.”
At trial, neither Velez nor Reyes testified definitively as to the contents of the blocks. Velez, who was at the Caguas station but not in the room when the blocks were analyzed, stated that she “believe[d]” they tested positive for cocaine. Reyes’s only testimony that the seized blocks were cocaine was' his 2002 statement memorializing the incident, which he read into the record. In the statement, he reported that Rodriguez had performed a field test on the evidence which yielded a positive result for cocaine. Reyes did not testify, however, that he was present when the field test was performed, and Rodriguez himself did not testify at trial.
The government then called Morales, as its expert witness, to testify regarding the composition of the seized substance. After outlining the Institute’s intake and chain of custody procedures, Morales began to discuss the results of Borrero’s test. Defense counsel objected on the basis that Morales had no personal knowledge of the underlying analysis, but the trial court determined that, based on Morales’s experience and familiarity with official procedure 1 he should be allowed to testify as to the veracity of this particular test. Morales -in fact had no involvement in testing the seized substance, and was no longer working in Borrero’s department when the testing occurred.
Morales confirmed that the evidence envelope entered by the government bore the signature of his colleague José Borrero, which he recognized from their years of working together. Based on the envelope’s unique number, Morales explained that the analyzed substance was that which had been seized by Reyes and delivered to the Institute by Rodriguez, and that it was evidence in a matter involving Ramos. He verified that the information on the evidence envelope matched the results reported in Borrero’s certificate of analysis, and when questioned about those results, provided the following testimony:
PROSECUTOR: Do you know the results of — I’m sorry. Looking at the envelope here, can you say what are the results of this test that was conducted? MORALES: Both bricks were positive for cocaine, and had a combined weight of 2,116 grams, including its wrapping in the plastic.
No further evidence was introduced at trial to prove that the blocks seized from the truck contained cocaine.
Ramos was ultimately convicted by a jury and sentenced to 327 months in prison. This timely appeal ensued.
II. Analysis
A. Standard of Review
We first address the appropriate standard of review for the Sixth Amendment claim. The government argues that because Ramos did not specifically invoke
*4
the Sixth Amendment in his objection, he failed to preserve a cognizable Confrontation Clause challenge.
See United States v. Mercado,
I originally thought [Morales] was the chemist who conducted the analysis of these controlled substances, but I believe [he is] not. It was Mr. Borrero. So I object to the fact that he has no personal knowledge of the test being conducted.
(emphasis added). In context, it was clear that counsel was objecting to the inability to confront the declarant.
See United States v. Cabrera-Rivera,
B. Confrontation Clause Challenge
Ramos contends that Morales’s testimony regarding the substance of Borrero’s report was barred by the Sixth Amendment, as construed in
Crawford v. Washington,
The Sixth Amendment guarantees that “[i]n all criminal prosecutions, the accused shall enjoy the right ... to be confronted with the witnesses against him....” U.S. Const, amend. VI. In
Crawford,
which effected a shift in Confrontation Clause doctrine, the Supreme Court established a new constitutional baseline: admitting “testimonial” statements
2
of a witness not present at trial comports with the Sixth Amendment “only where the declarant is unavailable, and ... the defendant has had a prior opportunity to cross-examine [the declarant].”
In a decision which post-dates the argument in this case, the Court further clarified in
Bullcoming v. New Mexico,
— U.S. -,
These Supreme Court cases are instructive, but they do not squarely address an issue that must be explored in this case: the extent to which the Sixth Amendment permits an expert witness to disclose the substance of a previously
unadmitted
forensic lab report that he did not draft.
See Bullcoming,
The government argues primarily that, unlike in
Melendez-Diaz,
Morales’s testimony constituted permissible expert review of Borrero’s report, which was itself never actually offered as evidence.
See
Fed.R.Evid. 703 (explaining that facts or data of a type upon which experts in the field would reasonably rely in forming an opinion need not be admissible in order for the expert’s opinion based on the facts and data to be admitted). Absent further clarification from the Court, the reconciliation of
Crawford, Melendez-Diaz,
and
Bull-coming
— which forbid the introduction of testimonial hearsay as evidence in itself— with Rule 703, which permits expert reliance on otherwise inadmissible testimonial hearsay, will necessarily involve a case-by-case assessment as to the quality and quantity of the expert’s reliance.
See United States v. McGhee,
More specifically, the assessment is one of degree. Where an expert witness employs her training and experience to forge an independent conclusion, albeit on the basis of inadmissible evidence, the likelihood of a Sixth Amendment infraction is minimal.
See United States v. De La Cruz,
The government is hard-pressed to paint Morales’s testimony as anything other than a recitation of Borrero’s report. On direct examination, the prosecutor asked Morales to “say what are the results of the test,” and he did exactly that, responding “[b]oth bricks were positive for cocaine.” This colloquy leaves little room for interpretation. Morales was never asked, and consequently he did not provide, his independent expert opinion as to the nature of the substance in question. 3 Instead, he simply parroted the conclusion of Borrero’s report. Morales’s testimony amounted to no more than the prohibited transmission of testimonial hearsay. While the interplay between the use of expert testimony and the Confrontation Clause will undoubtedly require further explication, the government cannot meet its Sixth Amendment obligations by relying on Rule 703 in the manner that it was employed here.
As an alternative basis for admissibility, the government points to language from
Melendez-Diaz
to argue that “it is not the case[] that anyone whose testimony may be relevant in establishing the chain of custody, authenticity of the sample, or accuracy of the testing device, must appear in person----”
Reciting the conclusion of Borrero’s report into the record raised a host of concerns, to which Morales was ill-equipped to reply. For example, defense counsel could not effectively query Morales about whether any circumstance or condition affected the integrity of the sample or the validity of the analysis, and what test and testing process Borrero employed.
See Bullcoming,
C. Harmlessness of the Error
The government argues that any Sixth Amendment error was harmless beyond a reasonable doubt.
See Cabrera-Rivera,
The harmlessness determination in this case depends principally on whether the information disclosed by Morales was merely cumulative of the testimony offered by Officers Reyes and Vélez. In so arguing, the government asserts that “[a]n officer is permitted to express his opinion that a field tested substance is cocaine,”
see United States v. Paiva,
For example, in
Valenciar-Lucena,
we held that the “[ijdentification of a substance as a drug may be based upon the opinion of a knowledgeable lay person,” where that lay person was a confidential informant who was formerly one of the drug-traffickers, and who had both intimate knowledge of the alleged conspiracy to distribute and prior direct contact with the drugs.
By contrast, the indicia of reliability here were far less substantial. Neither Vélez nor Reyes testified as to the nature of the substance based on their experience or intimate knowledge. The sum of their testimony consisted of Vélez’s statement that the blocks “appeared to be a controlled substance,” and the officers’ recollections that Rodriguez’s preliminary field test — for which they were not present-showed the presence of cocaine. This is not the type of specially reliable lay testimony that was proffered in Valenciar-Lucena or Paiva, and it does not meet the stringent requirement of proof beyond a reasonable doubt.
Further, to the extent that the government argues that there was additional corroborating evidence, that evidence does not go to the central issue. The fact that several law enforcement agents identified Ramos as the truck’s operator, and the presence inside the truck of various identifiers bearing Ramos’s name, go to the question of whether Ramos was in fact the driver of the truck, and not whether, as Morales concluded, the substance in the truck was cocaine.
Accordingly, Morales’s testimony was neither cumulative of nor sufficiently corroborated by alternative evidence, and it comprised the only compelling basis for the jury to conclude a critical element of the government’s case — that the substance seized from the truck was cocaine. We cannot conclude that the presence of cocaine would have been proved without the testimony of Morales, and therefore the admission of his testimony was not harmless beyond a reasonable doubt.
III. Conclusion
Although Ramos presses additional claims of error, we need go no further. For the reasons set forth above, we vacate the judgment of conviction and remand to the trial court for further proceedings. It is so ordered.
Notes
. At the time of his testimony, Morales had been employed as a chemist with the Institute for eight years. He worked for six years in the controlled substances division and in 2007 moved to forensic chemistry.
. A
statement ranks as "testimonial” where it has a "primary purpose of establishing or proving past events potentially relevant to later criminal prosecution.”
Bullcoming v. New Mexico,
— U.S. -,
. The government acknowledged at oral argument that Morales was never asked to give his independent opinion as to the nature of the substance.
