Rule of Law:
Electronic communications, such as emails, may be authenticated by the proponent through circumstantial evidence, known as 'confirming circumstances,' sufficient for a reasonable jury to find by a preponderance of the evidence that the defendant was the author.
Facts:
- The defendant, Purdy, owned and operated the About Hair Salon, which also functioned as a massage parlor.
- On September 22, 2005, undercover Detective Cherubino visited the salon. Purdy offered him a massage with 'extras,' such as the masseuse being 'topless' or 'totally nude' for an additional fee.
- During the massage, a masseuse named Lydia described other sexual services available, including 'pop the cork' (anal intercourse) and a 'Russian ending,' and told the detective to speak with Purdy if he wanted any extras.
- On October 4, 2005, undercover Detective Hyde visited the salon and overheard Purdy on the phone describing a 'Russian ending' as a 'satisfactory ending to the session between a woman’s breasts.'
- Hyde paid Purdy for a massage with a 'topless' extra and received the service from a masseuse.
- On October 7, 2005, police executed a search warrant and seized a desktop computer from the salon.
- Purdy admitted to police that the computer was his, that he used it, and he provided from memory the passwords needed to access its programs.
- A search of the computer's hard drive revealed numerous email exchanges sent from an account bearing Purdy's name, which he admitted using, that discussed hiring women and arranging sexual services for clients.
Procedural Posture:
- The defendant, Purdy, was convicted by a jury in a state trial court of deriving support from the earnings of a prostitute and maintaining a house of prostitution.
- The defendant appealed his convictions to the Massachusetts Appeals Court, which is an intermediate appellate court.
- The Appeals Court affirmed the convictions in an unpublished memorandum and order.
- The defendant then applied for further appellate review by the Massachusetts Supreme Judicial Court, the state's highest court, which granted the application.

Issue:
Are emails sufficiently authenticated as having been authored by the defendant when they are found on the hard drive of a computer he owns, originate from an email address bearing his name that he acknowledges using, he provides the passwords to access the computer, and the emails' contents align with his known activities?
Opinions:
Majority - Gants, J.
Yes, emails may be sufficiently authenticated through confirming circumstances even without direct evidence of authorship. Here, the evidence was sufficient for a reasonable jury to find that the defendant authored the emails. The court affirmed the conviction for deriving support from the earnings of a prostitute but vacated the conviction for maintaining a house of prostitution. The court reasoned that authorship can be established by circumstantial evidence, adapting traditional authentication principles for letters and phone calls to electronic communications. The 'confirming circumstances' in this case included that the emails came from Purdy's named account on a computer he owned, he provided the passwords, and the emails' content described his unique business operations. The court also held that while the trial judge erred in failing to provide a limiting instruction regarding a masseuse's out-of-court statements, the error was not prejudicial to the first conviction due to other overwhelming evidence of Purdy's guilt. However, the conviction for maintaining a house of prostitution was overturned because the trial judge gave an erroneous jury instruction defining 'sexual intercourse' to include acts beyond penile-vaginal penetration, which is the statute's sole definition, and the evidence was legally insufficient to prove that specific act was offered.
Analysis:
This case establishes an important precedent for authenticating digital evidence in the modern era, particularly emails and social media messages. It clarifies that the standard for authentication does not require direct proof, like an eyewitness to the creation of the message, but can be met through a collection of circumstantial 'confirming circumstances.' This flexible, fact-based approach makes it easier for prosecutors to admit digital communications, shifting the battleground from admissibility to the weight the jury should give the evidence. The decision also underscores the importance of precise statutory interpretation, as the narrow definition of 'sexual intercourse' was dispositive in vacating one of the convictions.
