Summary
The Tenth Circuit affirmed drug conspiracy and possession convictions, holding that sufficient evidence supported a single overarching conspiracy despite three separate drug transactions and that the defendant's arrest for a state drug offense did not automatically terminate his membership in the conspiracy absent affirmative withdrawal. The court also rejected a chain-of-custody challenge, finding that a reasonable jury could infer the tested drugs were the same as those seized from the defendant's vehicle based on matching weights and shipping dates. Key topics: conspiracy interdependence, withdrawal by arrest, multiple-conspiracy variance, chain-of-custody sufficiency, and drug possession under 21 U.S.C. § 841(b)(1)(A)(viii).

Questions Presented
- Whether the evidence was sufficient to support the conspiracy conviction, specifically whether the government proved a single overarching conspiracy rather than multiple conspiracies.
- Whether the district court erred in admitting evidence of events that occurred after Serr's October 2016 arrest, because his arrest automatically terminated his participation in the conspiracy.
- Whether the evidence was sufficient to support the possession with intent to distribute conviction given a gap in the chain of custody of the methamphetamine.
Holdings
- The evidence was sufficient for a reasonable jury to find a single conspiracy. Serr's single act of attempting to deliver methamphetamine demonstrated interdependence with the other conspirators, and the conspiracy did not splinter into multiple conspiracies merely because of separate transactions.
- Serr's arrest did not automatically withdraw him from the conspiracy. Affirmative action is required to withdraw; arrest alone is insufficient unless the arrest is for the conspiracy itself. Serr was arrested for possession, not conspiracy, and did not affirmatively withdraw.
- Despite a gap in the chain of custody (no direct testimony that the California lab received the exact drugs mailed from Colorado), the circumstantial evidence of matching dates and weights allowed a reasonable jury to conclude the tested drugs were the same as those seized from Serr.
Key quotations
“To prove a conspiracy, the government must establish: (1) that an agreement existed between two or more people to violate the law; (2) that the defendant knew at least the conspiracy's essential objectives; (3) that the defendant knowingly and voluntarily became a part of the conspiracy; and (4) that the co[]conspirators were interdependent.” (5)
“to withdraw from a conspiracy, an individual must take affirmative action, either by reporting to the authorities or by communicating his intentions to the coconspirators.” (10)
“deficiencies in the chain of custody affect the weight of the evidence, not its admissibility” (13)
Factual background
From October 2016 to May 2018, a group including Serr conspired to distribute methamphetamine from Colorado to Virginia. In October 2016, Serr attempted to deliver one pound of methamphetamine from coconspirator Zarate-Suarez to Fitzgerald in Kansas City but was stopped by police and arrested. He was found with 433.5 grams of methamphetamine. After his arrest, the conspiracy continued with two more transactions in November 2016 and May 2018, involving other members. Serr was later found at Zarate-Suarez's house after the May 2018 arrest of other conspirators.
Procedural history
Serr was convicted by a jury in the District of Colorado on two counts: conspiracy to distribute methamphetamine and possession with intent to distribute. He was sentenced to the statutory minimum of ten years. He appeals.
