United States v. Melendez-Santiago, 644 F.3d 54

Meléndez-Santiago was convicted after a 28-day trial of conspiracy to import cocaine and heroin and actual importation of cocaine as part of a large drug organization.
He argued the district court erred by not suppressing conversations recorded under two Title III wiretaps due to allegedly defective affidavits and lack of Franks hearing, and by denying suppression of his statements as involuntary.
The district court denied both suppression motions in Melendez II and Melendez I respectively; the court also noted the wiretaps were based on affidavits by FBI agent Mena supporting necessity.
The wiretap applications detailed the investigation’s progress, limited surveillance success, and reasons why traditional methods risked tipping off conspirators; they cited confidential sources and pen/trap data.
The government contends the affidavits were more than minimally adequate, and the district court found Meléndez voluntarily and knowingly waived his rights during two custodial interviews.
On appeal, the First Circuit affirmed, holding no Franks hearing was required and the statements were voluntary with valid Fifth and Sixth Amendment waivers.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Were the wiretap affidavits sufficient to support necessity?	Meléndez argues affidavits failed to show necessity and inadequately explained alternatives.	Government argues affidavits were thorough and satisfied § 2518(1)(c) necessity.	Affidavits were sufficient to support necessity.
Did the allegedly omitted information require a Franks hearing?	Meléndez claims omissions about Dominican origin and undercover risk mandate a Franks hearing.	Government contends omissions were immaterial and did not undermine probable cause.	No Franks hearing required; omissions did not affect probable cause.
Were Meléndez's statements to investigators voluntary under the Fifth and Sixth Amendments?	Meléndez contends coercive pressure and lack of counsel rendered statements involuntary.	Government asserts the district court properly credited agents and found voluntary cooperation.	Statements were voluntary; valid waivers of Fifth and Sixth Amendment rights.
