The background was as follows. The victim was shot to death during an armed home invasion. “Investigating officers seized a number of items from the crime scene…. [A] State police chemist conducted DNA testing of swabs taken from [those items]. She uploaded the profiles into the [national] CODIS database to search for a match. The DNA on [three of the items] matched the defendant’s DNA profile. Based on these results, police obtained a buccal swab from the defendant, which was submitted to the State police crime laboratory for DNA testing. A different State police chemist determined that the DNA on the [seized items] matched the defendant’s DNA.” In his appeal, “[t]he defendant contend[ed] … that testimony that DNA taken from items found at the crime scene matched his DNA profile in the CODIS database was inadmissible hearsay and a violation of his right to confrontation.”
In its decision, the SJC stated that “for the limited purpose of explaining the state of police knowledge,” “the Commonwealth [was] permitted to introduce evidence that an investigator submitted crime scene DNA samples to a national database.” However, stated the Court, the test results obtained from that database inquiry (the match to the defendant’s DNA) were inadmissible hearsay “because those responsible for conducting the CODIS database testing did not testify and were not subject to cross-examination.” Nonetheless, the Court concluded that the error was not prejudicial because “[a]part from this testimony regarding the match …, State police crime laboratory chemists also testified to the match found using the defendant’s DNA profile obtained from the buccal swab. Therefore, evidence of a match was independently before the jury.” In a similar vein, the Court opined that “[b]ecause the testimony involving the CODIS DNA match was testimonial hearsay admitted through a State police trooper without proper foundation to establish personal knowledge [as to the creation and maintenance of the database], its admission violated the defendant’s right of confrontation under the Sixth Amendment and art. 12 [of the Massachusetts Declaration of Rights].” However, stated the Court, the error was harmless beyond a reasonable doubt.
