United States v. Juan Lugo, 702 F.3d 1086

Lugo pleaded guilty to conspiracy to manufacture, distribute, and possess with intent to distribute methamphetamine and marijuana under 21 U.S.C. §§ 846, 841(a)(1).
District court sentenced Lugo to 240 months; affirming the sentence on sentencing-dating grounds.
PSR proposed base offense level 38 for quantity, +4 for leadership, −3 for acceptance of responsibility; total offense level 39.
Lugo challenged the court’s finding that the methamphetamine was “ice” (80%+ d-methamphetamine hydrochloride) rather than a mixture.
Court reduced base offense to 36 based on ice alone and proceeded with an adjusted total offense level of 37, sentencing Lugo to 240 months.
We affirm the sentence, concluding the district court’s identification of the substance as hielo/ice was not clearly erroneous and Walker governs.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the district court clearly erred in identifying the substance as ice.	Lugo argues no testing occurred to prove purity; identity not shown.	Lugo maintains lack of laboratory testing invalidates ice finding.	No clear error; identity supported by testimony and circumstantial evidence.
Whether purity testing is required to prove drug type for sentencing.	Government need not prove purity beyond preponderance.	Testing is necessary to prove purity/identity.	Guidelines do not require laboratory testing to establish methamphetamine as ice.
Whether Walker controls the decision despite an actual seizure.	Walker supports relying on non-lab evidence identifying ice.	Walker applies regardless of seizure.	Walker controls; no clear error in using non-testing evidence.
What evidence suffices to prove drug identity when testing is limited.	Conspirator testimony suffices for identity.	Appearance, price, and form can establish identity.	Circumstantial and witness testimony can establish drug identity.
