State v. Herrera, 315 P.3d 343

Background

Herrera shot a friend outside his home; the friend later died. Herrera admitted shooting but claimed self-defense or, alternatively, provocation reducing the crime to manslaughter.
After the shooting Herrera hid the handgun in a crawlspace; police later found it. He was charged with first-degree murder and third-degree tampering with evidence (tampering with evidence of a capital, first- or second-degree felony).
Jury convicted Herrera of second-degree murder and third-degree tampering with evidence.
The tampering jury instruction tracked the statutory conduct (hide firearm; intent to avoid prosecution) but omitted an instruction that the tampered evidence related to a capital, first- or second-degree felony (an element that increases punishment under NMSA §30-22-5(B)).
Herrera did not preserve the instructional error at trial; he raised it on appeal along with claims about a witness comment concerning his post‑Miranda silence, admission of ammunition evidence, and various jury-instruction issues.

Issues

Issue	State's Argument	Herrera's Argument	Held
Whether the tampering statute's subsection identifying the underlying crime (capital/first/second-degree) is an element that the jury must find	Implicitly conceded that subsection (B) factors are elements but argued the omission did not require reversal because evidence showed the tampered item related to the murder	Omitted element violated Sixth and Fourteenth Amendments; jury must find the underlying crime type beyond a reasonable doubt	The court held the subsection (B) crime-type is an element under Apprendi/Jones/Alleyne, but the omission was not fundamental error because the record uncontrovertibly showed the gun related to the second-degree murder the jury found.
Whether the unpreserved jury-instruction error was fundamental (warranting reversal)	The State argued the error was not fundamental because evidence established the missing element beyond a reasonable doubt	Herrera argued any omission of an essential element is fundamental and requires reversal when not submitted to the jury	Court held error was not fundamental: evidence was overwhelming and uncontroverted that the tampering related to the murder (second-degree felony), so fairness/integrity of proceeding was not undermined.
Whether a detective's comment that Herrera spoke after being read Miranda (implying post-Miranda silence) required a mistrial	The State noted the comment was elicited by defense counsel and the prosecutor did not exploit it; law enforcement comments are not automatically attributable as prosecutorial misconduct here	Herrera argued the comment impermissibly referenced his post-Miranda silence and required a mistrial	Court denied relief: no reversible error since the comment was not elicited by prosecutor, was isolated/unsolicited, and was not exploited in closing.
Admission of evidence about multiple types of ammunition found at Herrera's house	State maintained the evidence was admissible; relevance and proper foundation supported admission	Herrera argued admission of ammunition that could not have been fired from the murder weapon was prejudicial	Court declined to reach the undeveloped argument; Herrera failed to preserve/brief the claim adequately, so no relief.
