v. No. 24-6130 (D.C. No. 5:23-CR-00237-SLP-2) TONG LIN, (W.D. Okla.)
Defendant - Appellant. _________________________________
ORDER AND JUDGMENT * _________________________________
Before HOLMES, Chief Judge, SEYMOUR, and BACHARACH, Circuit Judges. _________________________________
Defendant Tong Lin appeals his conviction for conspiracy to possess with the
intent to distribute 1,000 or more marijuana plants, a Schedule I controlled substance, in
violation of 21 U.S.C. § 846. He argues on appeal that: (1) the evidence was insufficient
to support the jury’s verdict, (2) the district court erred in excluding evidence of his belief
that the distribution of marijuana was legal under state law, (3) the district court erred in
instructing the jury on deliberate ignorance, and (4) there was cumulative error sufficient
to reverse the jury’s verdict. For the reasons explained below, we reject each of these
arguments and affirm Mr. Lin’s conviction.
This order and judgment is not binding precedent, except under the doctrines *
of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1. Appellate Case: 24-6130 Document: 46-1 Date Filed: 03/24/2025 Page: 2
I. Background 1
In late 2021 and early 2022, the FBI, Oklahoma Bureau of Narcotics, and the
Oklahoma City Police Department started an investigation into illegal marijuana
distribution in Oklahoma. This investigation led law enforcement to conclude that
Brandon Ye was collecting marijuana from grow locations throughout Oklahoma for
redistribution out of state. Mr. Ye used multiple vehicles to conduct these collections,
including a van marked as belonging to Arch Granite (his former business) and a blue
Mercedes sprinter van disguised as an Amazon delivery van.
Beginning in April 2022, Mr. Ye would use these vans (first the Arch Granite
van and later the fake Amazon van) to make collections from black market marijuana
grows throughout Oklahoma. Several times per week he collected hundreds of
pounds of marijuana, vacuum-sealed in individual packages and contained in black
trash bags or in commercial boxes from, among other places, Home Depot, and
brought it back to his Arch Granite warehouse. On Fridays, the collected marijuana
was loaded into a semi-truck and driven out of state for further distribution.
One of the grows Mr. Ye visited approximately a dozen times over a four-
month period was a black-market marijuana grow location in Wetumka, Oklahoma
operated by Jeff Weng and Mr. Lin. Mr. Ye picked up about 150 pounds of marijuana
each time he visited, and Mr. Lin was one of the people who helped him load the
bags and boxes of marijuana into his fake Amazon van.

On May 17, 2023, law enforcement executed a search warrant on the Wetumka
grow. Agents seized 19,661 marijuana plants and 460 pounds of processed or loose
marijuana. They also found and seized a firearm and holster, and two bundles of
vacuum-sealed cash totaling over $100,000 hidden in the attic above the master
bedroom closet. Law enforcement also interviewed Mr. Lin, who told them he had
worked at the grow for five months and described himself as a “management intern.”
Rec., vol. I at 275. Mr. Lin’s initials appeared on employee to-do lists posted on
several of the buildings.
Mr. Lin was charged with one count of conspiracy to possess with the intent to
distribute 1,000 or more marijuana plants, a Schedule I controlled substance, in
violation of 21 U.S.C. § 846. Mr. Lin pled not guilty but was convicted by a jury at
trial and sentenced to 120 months’ imprisonment together with a term of supervised
release of five years. This timely appeal followed.
II. Analysis
Mr. Lin challenges his conviction on several different grounds. First, he
contends that the government failed to provide sufficient evidence that the plants
recovered from the Wetumka grow were in fact marijuana. Because Mr. Lin did not
move for a judgment of acquittal as required under Federal Rule of Criminal
Procedure 29(a), we review his sufficiency of the evidence claim for plain error.
The jury heard evidence that the site was a state-licensed medical marijuana
grow. It also heard evidence from Mr. Ye that the substance he collected from the
Wetumka grow was marijuana. Though the government provided significantly more 3 Appellate Case: 24-6130 Document: 46-1 Date Filed: 03/24/2025 Page: 4
evidence than this, these two examples alone are more than sufficient to uphold the
jury’s finding that the plants in question were marijuana.
Second, Mr. Lin argues that the evidence was insufficient to prove his
knowledge that possession and distribution of marijuana was illegal and argues that
he should have been able to present evidence to the jury that he was unaware of the
discrepancy between state and federal law regarding the legality of marijuana. We
address these two related issues in turn.
The parties disagree about what the government’s burden is in this case. Mr.
Lin contends that the government must prove he knew that the substance in question
was controlled (even if he didn’t know exactly what the substance was). The
government argues that it could also prove simply that Mr. Lin knew what the
substance was, even if he didn’t know that it was controlled. The argument turns on
whether dicta from McFadden v. United States, 576 U.S. 186 (2015), should still
control. However, we have no need to reach this question yet, as the evidence
presented at trial was more than sufficient for a reasonable jury to find that Mr. Lin
knew both that he was dealing with marijuana, and that he was doing so outside the
law. “The government can, and ordinarily does, prove knowledge and intent through
circumstantial evidence.” United States v. Banks, 884 F.3d 998, 1018 (10th Cir.
2018). “[I]n fact, it is rarely established by other means.” United States v. Nguyen,
413 F.3d 1170, 1175 (10th Cir. 2005). Here, the circumstantial evidence was
substantial. A firearm and over $100,000 in cash were found at the grow, items
associated with the illegal distribution of drugs. Given Mr. Lin’s managing role at the

4 Appellate Case: 24-6130 Document: 46-1 Date Filed: 03/24/2025 Page: 5
grow in Mr. Weng’s absence, the government contends the jury could have
reasonably inferred that he knew of and had access to the gun and the cash. Even
more compelling, however, is the fact that Mr. Lin helped load the marijuana into the
fake Amazon delivery truck. Mr. Lin saw and participated in the great efforts Mr. Ye
took to conceal the marijuana; not only was it transported in a fake Amazon delivery
truck, but within the truck it was stored in vacuum-sealed bags and packed in retail
store boxes. Simply put, Mr. Lin either knew what he was doing was illegal, or he
didn’t want to know (which foreshadows an argument we will address promptly).
“A district court has broad discretion to determine the admissibility of
evidence, and we review the district court’s ruling for abuse of discretion.” United
States v. Merritt, 961 F.3d 1105, 1111 (10th Cir. 2020). Mr. Lin argues that the
district court erred in granting the government’s motion in limine, excluding any
evidence of the defendants’ alleged compliance with state law. We disagree. Turning
to the earlier question of McFadden, this Court has already specifically adopted the
two methods of establishing the mens rea set forth therein. “[U]nder McFadden it
was enough that Defendant knew that he was distributing fentanyl, regardless of
whether he knew that it was a controlled substance.” United States v. Shamo, 36
F.4th 1067, 1076 (10th Cir. 2022). This panel “cannot overrule the judgment of
another panel,” and we are “bound by the precedent of prior panels absent en banc
reconsideration or a superseding contrary decision by the Supreme Court.” United
States v. Manzanares, 956 F.3d 1220, 1225 (10th Cir. 2020). No such en banc
reconsideration has occurred nor has a superseding contrary decision been issued. As
5 Appellate Case: 24-6130 Document: 46-1 Date Filed: 03/24/2025 Page: 6
a result, all the government had to prove in this case to establish sufficient mens rea
was that Mr. Lin knew the substance was marijuana; his subjective beliefs about its
legality, however well-founded, are completely irrelevant. 2
Mr. Lin also raises the issue of entrapment by estoppel, but he does so after
having waived it. We accordingly decline to address it. See United States v. Bradley,
97 F.4th 1214, 1221 (10th Cir. 2024) (“‘When an appellant fails to preserve an issue
and also fails to make a plain-error argument on appeal, we ordinarily deem the issue
waived (rather than merely forfeited) and decline to review the issue at all—for plain
error or otherwise.’” (quoting United States v. Leffler, 942 F.3d 1192, 1196 (10th Cir.
2019)).
Turning to jury instructions, Mr. Lin argues that the district court’s inclusion
of the Tenth Circuit Pattern Jury Instruction on deliberate ignorance constituted plain
error. But we find no error, plain or otherwise. “A deliberate ignorance instruction is
appropriate when a defendant denies knowledge of an operant fact but the evidence,
direct or circumstantial, shows that defendant engaged in deliberate acts to avoid
actual knowledge of that operant fact.” United States v. Delreal-Ordones, 213 F.3d
1263, 1268 (10th Cir. 2000). “The district court need not insist upon direct evidence
of conscious avoidance of a fact before tendering a deliberate ignorance instruction.”
Id. Instead, the district court may “rely on circumstantial evidence and the benefit of
2 Because irrelevancy is sufficient justification to exclude evidence, we decline to address the district court’s additional finding that the proffered evidence was prejudicial and could lead to jury nullification. 6 Appellate Case: 24-6130 Document: 46-1 Date Filed: 03/24/2025 Page: 7
the favorable inferences to be drawn therefrom.” Id. Such is the situation in this case.
If Mr. Lin did not know that he was participating in an illegal conspiracy as he
packed marijuana into a fake Amazon delivery truck, it raises the reasonable question
of whether he was willfully ignorant—exactly the circumstances that would call for a
deliberate ignorance jury instruction.
Because we have determined the district court did not err in deciding any of
the issues raised on appeal, we decline to consider Mr. Lin’s argument for cumulative
error.
III. Conclusion
Mr. Lin has not shown that the evidence against him was insufficient to sustain
his conviction, nor has he shown any error on the part of the district court.
Accordingly, we affirm.
