Quick Summary
Alfred Trenkler (defendant) was convicted for his role in a fatal bombing in Roslindale, Massachusetts. Thomas Shay Jr. (co-defendant) was implicated as his accomplice. The central dispute revolved around whether evidence from a similar prior bombing in Quincy and computer database information could be admitted to establish Trenkler’s identity as the bomb maker.
The United States Court of Appeals for the First Circuit upheld Trenkler’s conviction after evaluating the admissibility of such evidence under Federal Rule of Evidence 404(b) and performing a Rule 403 analysis. The Court concluded that there was no abuse of discretion by the lower court.
Facts of the Case
Alfred Trenkler (defendant) was convicted for his involvement in a bomb explosion that occurred in Roslindale, Massachusetts, resulting in the death of a bomb squad member and severe injuries to another. The prosecution argued that Trenkler constructed the explosive device at the behest of Thomas Shay Jr. (co-defendant) for use against Shay Jr.’s father.
Additionally, the government sought to establish Trenkler’s identity as the bomb maker by introducing evidence of a similar bomb, which Trenkler had previously built and was used in Quincy, Massachusetts.
The similarities between the two bombs were central to the prosecution’s case, with components, design, and construction methods serving as indicators of Trenkler’s involvement. Furthermore, testimony regarding a computer database that identified characteristics of bombs was presented to link the two devices to Trenkler.
Procedural History
- Alfred Trenkler and Thomas Shay Jr. were indicted on charges related to the bombing in Roslindale.
- Trenkler filed for severance and was tried separately from Shay Jr., who was convicted on conspiracy and property destruction charges.

- After being convicted, Trenkler appealed to the United States Court of Appeals for the First Circuit, challenging the admission of evidence from the Quincy bombing and the computer database.
I.R.A.C. Format
Issue
Whether the district court erred in admitting evidence of a prior bombing incident and computer database information to establish Trenkler’s identity as the maker of both bombs.
Rule of Law
Federal Rule of Evidence 404(b) permits the use of evidence of other crimes, wrongs, or acts to prove motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident when such evidence is relevant to an issue other than the defendant’s character.
Reasoning and Analysis
The court’s analysis centered on whether evidence from the Quincy bombing had ‘special relevance’ under Federal Rule of Evidence 404(b) beyond demonstrating Trenkler’s propensity for criminal behavior. The court found that the distinct similarities between the Quincy and Roslindale bombs provided significant relevance on the issue of identity.
The court also conducted a Federal Rule of Evidence 403 analysis to determine if the probative value of this evidence outweighed any potential unfair prejudice against Trenkler.
The court further considered testimony regarding a computer database known as EXIS, which was used to establish similarities between the two bombings. Despite challenges to its admissibility, the court found that this evidence supported the inference that Trenkler had constructed both bombs.
Conclusion
The United States Court of Appeals affirmed Trenkler’s conviction, concluding that the district court did not abuse its discretion in admitting evidence from the prior Quincy bombing and the computer database information linking both bombs to Trenkler.
Dissenting Opinions
The dissent argued that admitting evidence derived from the EXIS computer database violated Trenkler’s Sixth Amendment right to confront witnesses against him and that this error was not harmless beyond a reasonable doubt. The dissent also contended that without this evidence, the government’s case consisted of circumstantial evidence and an unreliable jailhouse confession, which did not constitute ‘overwhelming evidence’ of guilt.
Key Takeaways
- Federal Rule of Evidence 404(b) allows for the admission of other crimes or acts as evidence if it is pertinent to an issue other than character.
- The similarity between separate incidents can be used to establish identity if they share distinguishing features indicative of a singular perpetrator.
- A Rule 403 analysis must be conducted to ensure that probative value is not substantially outweighed by unfair prejudice.
- The court will uphold evidentiary rulings unless there is a clear abuse of discretion.
