UNITED STATES OF AMERICA, v.

JIN GUANGHUA, Criminal Action No. 23-91-2 (CKK)

Defendant.

MEMORANDUM OPINION

(August 1, 2025)

Defendant Guanghua Jin faces a twelve-count indictment charging him with participation in a bank-fraud, money-laundering, and sanctions-evasion conspiracy. Jin moves the Court under the Fourth Amendment and Franks v. Delaware, 438 U.S. 154 (1978), to hold an evidentiary hearing to determine whether to exclude evidence seized in connection with the execution of a search and seizure warrant on his email account. For the reasons that follow, the Court shall DENY Jin’s motion.

I. BACKGROUND

The Government alleges that Jin, a Chinese national and Australian resident, conspired with several others between 2009 and 2019 to commit bank fraud, launder money, and evade U.S. sanctions on North Korea. See Indictment, ECF No. 13. In simplified form, Jin’s alleged scheme was as follows: Jin and his co-conspirators Qin Guoming and Han Linlin operated a series of companies, many of which had names including the word “Winney” (collectively, the “Winney Entities”). The Winney Entities brokered sales of products—principally bulk shipments of raw tobacco—from international suppliers to North Korean entities through U.S. dollar-denominated transactions that relied on correspondent banking services from U.S. financial institutions.

Because U.S. financial institutions would not knowingly process transactions for these entities due to anti-money laundering restrictions, and because the United States imposed country-wide sanctions against North Korea in 2016, Jin and the Winney Entities falsified shipping records and routed transactions through front companies in an effort to make it appear as if the shipments were being made in furtherance of legitimate trade with China. In sum, the Government alleges that, through the Winney Entities, Jin conspired to and did defraud U.S. financial institutions, helped North Korean entities illegally access the U.S. financial system, and launder the proceeds of those activities.

During its investigation into Jin and his co-conspirators, the Government sought a warrant to search and seize the contents of five email accounts, including the account identified as “jinguanghua2014@gmail.com.” See Mot. to Suppress and for Franks Hearing Ex. 1, ECF No. 46-1 at 2–5 (March 14, 2025). In its warrant application, the Government represented that it had reason to believe the target email accounts contained evidence of a crime, namely violations of 50 U.S.C. § 1705 (evasion of sanctions under the International Emergency Economic Powers Act) and 18 U.S.C. § 1956 (money laundering). ECF No. 46-1 at 2. On December 10, 2019, Magistrate Judge Robin M. Merriweather determined that the Government had demonstrated probable cause for the search and issued a warrant authorizing the search and seizure of the target email accounts. Id. at 2.

In finding probable cause, Magistrate Judge Merriweather relied on an affidavit in support of the Government’s warrant application sworn out by FBI Special Agent Joy Gallante. See ECF No. 46-1 at 3, 16-17. The Court will discuss the details of Agent Gallante’s affidavit in greater detail below, but in broad strokes, and as relevant to Jin’s email account, Agent Gallante’s affidavit offers five categories of support for the warrant application: (1) background information about

North Korean commerce and U.S. sanctions against North Korea (id. ¶¶ 7–18); (2) information gleaned from Government interviews with Cooperating Company 1, 1 a bulk tobacco seller that had done business with the Winney Entities (id. ¶¶ 18–21); (3) information revealed from subpoena returns from Cooperating Company 1 and financial institutions (id. ¶¶ 26–29); (4) information learned during the course of an undercover investigation, including a meeting between Jin and undercover agents (id. ¶¶ 22–25); and (5) information returned from prior court orders under 18 U.S.C. § 2703(d) (id. ¶¶ 33–35).

Jin filed the instant [34] Motion for a Franks Hearing and to Suppress the Fruits of Email Search Warrant (“Def.’s Mot.”), arguing that Agent Gallante’s affidavit contains materially false statements and omissions that, if corrected, would have precluded Magistrate Judge Merriweather’s probable-cause determination. The Government opposed Jin’s motion. See Gov’t’s Opp’n, ECF No. 64. And Jin replied. See Def.’s Reply, ECF No. 73. The matter is ripe for review.

II. LEGAL STANDARD

The Fourth Amendment prohibits “unreasonable searches and seizures” and provides that

“no Warrants shall issue, but upon probable cause, supported by Oath or affirmation.” U.S. Const. amend. IV. The Supreme Court has described the task of evaluating probable cause as “a practical, common-sense decision whether, given all the circumstances set forth in the affidavit . . . there is a fair probability that contraband or evidence of a crime will be found in a particular place.” Illinois v. Gates, 462 U.S. 213, 238 (1983). “When police obtain evidence by way of an unlawful

1 Cooperating Company 1 is Cooperativa de Tabacaleros de Jujuy. Elsewhere, the parties have agreed that Cooperating Company 1 need not be referred to pseudonymously moving forward. See Mem. Op. & Order, ECF No. 96, at 3–4. But Cooperating Company 1’s identity is immaterial to Jin’s motion. And Agent Gallante’s affidavit and the parties’ briefs use the pseudonym. So, for ease of reference, the Court does the same here.

search, the exclusionary rule may require exclusion of that evidence in some circumstances.” United States v. Glover, 681 F.3d 411, 418 (D.C. Cir. 2012).

But “the exclusionary rule has limited force in cases involving a search with a search warrant.” Glover, 681 F.3d at 418. In United States v. Leon, 468 U.S. 897 (1984), the Supreme Court instructed that, subject to narrow exceptions, courts may not exclude evidence “when an officer acting with objective good faith has obtained a search warrant from a judge or magistrate and acted within its scope.” Id. at 920. One exception to Leon’s default rule arises when “the magistrate or judge in issuing a warrant was misled by information in an affidavit that the affiant knew was false or would have known was false except for his reckless disregard for the truth.” Leon, 468 U.S. at 923.

That exception, which Jin invokes here, was originally set forth in Franks v. Delaware, 438 U.S. 154 (1978). Under Franks, if a defendant makes a “substantial preliminary showing,” the court must hold an evidentiary hearing to determine whether the fruits of the warrant should be excluded. 438 U.S. at 155–56. In this Circuit, the substantial preliminary showing necessary to trigger a Franks hearing requires a defendant to show that (1) the warrant affidavit contained false statements or omitted certain facts; (2) the false statements or omitted facts were material to the finding of probable cause; and (3) the false statements or omissions were made knowingly and intentionally, or with reckless disregard for the truth. United States v. Becton, 601 F.3d 588, 594 (D.C. Cir. 2010); United States v. Spencer, 530 F.3d 1003, 1007 (D.C. Cir. 2008).

“An affidavit offered in support of a search warrant enjoys ‘a presumption of validity.’”

United States v. Maynard, 615 F.3d 544, 550 (D.C. Cir. 2010) (quoting Franks, 438 U.S. at 171). To overcome that presumption, the defendant must make a “substantial showing” that is “more than conclusory” and “accompanied by an offer of proof.” Id. (quoting United States v. Gaston,

357 F.3d 77, 80 (D.C. Cir. 2004)). Additionally, false statements are “material” if, when they are “set to one side, the affidavit’s remaining content is insufficient to establish probable cause.” Franks, 438 U.S. at 156. By extension, omissions are material if “their ‘inclusion in the affidavit would defeat probable cause.’” Spencer, 530 F.3d at 1007 (quoting United States v. Colkley, 899 F.2d 297, 301 (4th Cir. 1990)).
