State v. Herrera, 315 P.3d 343

Background

Defendant Israel Herrera shot a friend outside his home; he then hid the firearm in a crawlspace under the house and was later arrested.
Charged with first-degree murder and third-degree tampering with evidence (tampering with evidence of a capital, first- or second-degree felony).
At trial Herrera admitted shooting but claimed self‑defense or, alternatively, sufficient provocation to reduce the offense to manslaughter.
The jury convicted Herrera of second‑degree murder and third‑degree tampering with evidence.
The tampering jury instruction tracked Subsection (A) (the act and intent) but omitted any requirement that the jury find the tampered evidence related to a capital, first‑, or second‑degree felony (the sentencing tier in Subsection (B)).
Herrera appealed, arguing omission of that element violated his Sixth and Fourteenth Amendment rights; the State conceded the omission was unpreserved, so review was for fundamental error.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Herrera)	Held
Whether the tampering statute’s sentencing-tier facts (type of underlying crime) are elements that must be found by a jury beyond a reasonable doubt	The State argued the omission was not preserved and any error was not fundamental because the evidence tied the tampering to the murder.	Herrera argued the jury must be instructed to find the tampered evidence related to a capital, first- or second-degree felony; omission violated his right to a jury determination of every element.	Court held the Subsection (B) tier facts are elements under Jones/Alleyne and must be jury-found, but omission here was not fundamental because the record overwhelmingly and uncontrovertedly showed the gun tampering related to the second‑degree murder the jury convicted him of.
Whether a witness’s statement that Herrera spoke after being Mirandized (implying post‑Miranda silence/invocation) required a mistrial	The State (responding to motion) maintained no reversible error because the comment was not solicited by prosecution and was isolated; prior‑authority attributing police statements to prosecutors did not extend here.	Herrera argued the detective’s comment constituted an improper reference to post‑Miranda silence and required a mistrial under Franklin/Boyer.	Court held no reversible error: the comment was made in response to defense questioning, was isolated, and prosecutor did not exploit it.
Admissibility of evidence that Herrera had multiple types of ammunition, including kinds not matching the murder weapon	State relied on relevance and that only one type matched the murder weapon; introduction was not objected to contemporaneously.	Herrera argued admission of unrelated ammunition was prejudicial under Franklin/Boyer.	Court declined to review the undeveloped argument and did not find reversible error in the record presented.
Instructional claims (imperfect self‑defense, manslaughter instruction) and sufficiency of evidence	State maintained existing New Mexico law and instructions (manslaughter covers imperfect self‑defense theory) were adequate; evidence supported convictions.	Herrera sought an imperfect self‑defense instruction and argued insufficiency of evidence for murder/tampering.	Court held imperfect self‑defense instruction not required (New Mexico law treats that concept within manslaughter instructions); sufficiency review affirmed convictions for second‑degree murder and tampering (intent to hide and connection to murder established by circumstantial evidence).
