People v. Thomas CA4/1, D082842

Adam Thomas was convicted by a jury of first-degree murder for killing his brother Trenton Thomas with a crossbow in San Diego in 2021.
Video surveillance, physical evidence, and testimony linked Adam to the scene; police later recovered weapon-related items near the crime scene and at Adam's Sacramento residence.
Adam testified he did not intend to kill Trenton, asserting the shooting was an accident during an attempted gift presentation.
At trial, Adam was impeached with statements he made during a police interrogation after he had invoked his right to counsel but ultimately chose to speak to detectives.
Adam moved to suppress these statements, arguing they were involuntary and coerced, but the trial court allowed them for impeachment purposes if Adam testified.
On appeal, Adam challenged the voluntariness of his statements under Miranda and constitutional standards, seeking reversal of his conviction.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Voluntariness of Custodial Statements	Statements were voluntary and not the result of coercion; admissible for impeachment	Statements were coerced, involuntary; should be excluded, especially after repeated requests for counsel	Statements were voluntary and admissible for impeachment; trial court did not err
Use of Impeachment Evidence	Permitted to use Miranda-violative statements for impeachment if voluntary	Not permissible because they were obtained after invoking right to counsel and via coercive tactics	Permitted if voluntary; Miranda violation alone does not bar impeachment use
Trial Court's Evidentiary Rulings	Court correctly relied on totality of circumstances and independent review	Court failed to give proper weight to requests for counsel and alleged psychological tactics	Court properly weighed all relevant factors and circumstances
Instructional Error (CALCRIM No. 510)	Change in law subsequent to trial rendered any instructional issue moot	Initially challenged modification of then-current jury instruction	Issue withdrawn; no error found due to intervening change in instruction
