Connecticut Supreme Court to Hear Manslaughter Appeal
The state's high court will review the 2023 conviction of Patrick Griffin on October 29.
Updated on Oct. 21, 2026 in Criminal Justice
The Connecticut Supreme Court is set to hear an appeal in the manslaughter case of Patrick Griffin on October 29. Griffin seeks to overturn his conviction for the 2022 stabbing death of James Knapp.
Why it matters
The appeal challenges critical trial procedures, specifically whether jurors were incorrectly instructed on self-defense law and if the defendant's constitutional rights were violated by questioning his post-arrest silence. A successful appeal could result in a new trial for the 63-year-old defendant.
Patrick Griffin is currently serving a 16-year prison sentence with 5 years of probation. The court will now weigh if procedural errors in the original trial require a legal reversal.

Legal Context
This case centers on constitutional interpretations similar to the precedents set in Doyle v. Ohio regarding the use of post-arrest silence. It highlights the ongoing tension in Connecticut courts between self-defense claims and the admissibility of defendant testimony.
Residents should note that this high-profile appeal may establish new benchmarks for how trial judges instruct juries on self-defense in Connecticut. The outcome could influence future criminal proceedings involving claims of preemptive force.
The takeaway
Appellate courts frequently re-examine cases where procedural or constitutional questions arise during trial testimony. Defendants aiming to use self-defense claims must be prepared for rigorous prosecutorial scrutiny of their post-arrest silence.
