Commonwealth v. Oppenheim
12 N.E.3d 502
Mass. App. Ct.2014Background
- Defendant David Oppenheim ran a community theater (PACE) and was convicted by a Superior Court jury of five counts of child rape based principally on victim Ann Ross’s testimony and corroborating witnesses.
- Key inculpatory evidence included an extended March 10 instant message (IM) from the defendant to Ryan DiMartino describing sexual acts with Ross, plus multiple oral admissions to other witnesses and testimony from former students about prior sexual conduct.
- DiMartino testified about a long-running IM relationship with the defendant, a February 13 name-change to mask identity, and identified stylistic and factual details in the March 10 IM as showing the defendant authored it.
- At a pretrial hearing the judge found sufficient corroborating circumstances to admit the IMs and instructed the jury that they must find by a preponderance of the evidence that the defendant authored the messages before considering their content.
- Defense objections at trial and in closing asked for a higher (beyond a reasonable doubt) authorship standard for admission and for the jury to be so instructed; the judge refused.
- The defendant also challenged (1) elicitation of witnesses’ positive background/credentials, (2) limits on cross-examining DiMartino about self‑mutilation and bondage, and (3) the judge’s excusal of student jurors during empanelment.
Issues
| Issue | Commonwealth's Argument | Oppenheim's Argument | Held |
|---|---|---|---|
| Authorshp/authentication of IM confession | Preponderance standard for preliminary fact of authorship; jury may consider message if judge finds author likely | Authorship must be proved beyond a reasonable doubt before jury may consider a defendant’s inculpatory IMs | Authorship/authentication is a preliminary fact decided by preponderance; jury instructed to consider IMs only if convinced by preponderance defendant authored them; no beyond‑reasonable‑doubt requirement imposed |
| Weight of witnesses’ positive credentials | Background/achievements respond to defense attack on credibility; permitted in rebuttal | Such testimony improperly bolstered prosecution witnesses and should be excluded | No reversible error; any incremental credentialing did not create substantial risk given strength of Commonwealth’s case and tactical choices by defense |
| Scope of cross‑examination of DiMartino (self‑mutilation, bondage) | Judge allowed broad impeachment and excluded only marginally relevant/prejudicial topics | Exclusion of these subjects denied meaningful impeachment and was prejudicial | No abuse of discretion; limits were reasonable given relevance/prejudicial balance and did not prejudice defendant |
| Excusal of student jurors during empanelment | The court’s individualized hardship approach was proper; no systematic exclusion | Systematic exclusion of students denied jury with online-savvy peers and prejudiced defendant | No reversal: defendant failed to timely object under G. L. c. 234A § 74; judge did not apply a categorical student exemption and excusals were individualized |
