United States v. Anthony Martinez, Jr., 410 F. App'x 759

Police received midnight calls about multiple shots fired; a large police presence responded and converged on Martinez's home.
Martinez admitted firing several weapons that night during a protective sweep after a preliminary detention.
The officers discovered a gun safe inside the home and numerous firearms, with shell casings from multiple calibers and 12 people present (including Martinez's 14-year-old son).
Three firearms fired that night were identified; serial numbers of additional guns in the safe were recorded after the seizure.
Two firearms remained stolen and were later seized under a federal warrant; Martinez was indicted on machine gun charges under federal law.
Martinez challenged the admissibility of the serial-number records and sought a two-level reduction for acceptance of responsibility at sentencing, which the district court denied.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Was Martinez's consent to search voluntary?	Martinez contends the search was not voluntary.	Martinez argues the search was coerced by police presence and custodial status.	Consent found voluntary under totality of circumstances.
Did implicit requests for consent render consent valid?	Consent was not clearly consented to; silence was not consent.	Silent acquiescence after implied request to locate weapons constitutes consent.	Implicit consent supported by conduct; voluntary and valid.
Did the scope of consent extend to recording serial numbers of all firearms?	Scope limited to firearms fired that night.	Scope reasonably included all firearms in the safe for identification and inventory.	Scope extended to serial-number recording of all guns in the safe.
Was recording serial numbers justified under plain view or as within consent scope?	Plain view or consent scope does not cover serial-number logging for all guns.	Plain view and inventory purposes justified the recording.	Supported by plain-view and scope of consent; proper seizure of serial numbers.
Whether the district court erred in denying a two-level acceptance of responsibility reduction at sentencing?	Cooperation and attempt at conditional plea justify reduction.	Misrepresentations at suppression and other conduct negate acceptance.	District court's denial affirmed; no 'clear error' in weighing conduct and responsibility.
