MONTECALVO, Circuit Judge. Defendant Adiangel Paredes appeals from his conviction following a jury trial, of one count of conspiracy to distribute and to possess with intent to distribute one kilogram or more of heroin, 400 grams or more of fentanyl, and 500 grams or more of cocaine in violation of 21 U.S.C. § 846. Paredes now argues that, at trial, (1) the district court erroneously permitted testimony about the meaning of various telephone calls and text messages admitted into evidence, and (2) the evidence presented varied from the allegations contained in the indictment. For the reasons that follow, we are not persuaded by either argument and, accordingly, affirm.

I. Background

We recite the facts in "the light most favorable to the verdicts being appealed." United States v. Mangual-Santiago, 562 F.3d 411, 418 (1st Cir. 2009) (citing United States v. Sanchez-Badillo, 540 F.3d 24, 27 (1st Cir. 2008)). In September 2018, the Boston Strike Force of the Federal Bureau of Investigation ("FBI") began investigating an alleged drug trafficking organization ("DTO") operating in Fitchburg, Massachusetts. The FBI identified Anthony Baez and another individual who later became a confidential witness ("CW-6") as the leaders of the DTO. FBI agents worked with two other confidential witnesses to arrange drug purchases (referred to as "controlled

purchases") from Baez and CW-6, purchasing increasingly larger amounts of drugs.

During the investigation, the FBI obtained wiretaps on telephones belonging to several individuals involved in the DTO, namely, Baez, Pablo Vidarte Hernandez, CW-6, and Paredes. The FBI identified Paredes after intercepting a telephone call between Baez and Vidarte. During that telephone call, Baez asked for the price of cocaine, and, after hanging up, Vidarte immediately called a telephone number later connected to Paredes. Following that call, Vidarte immediately called Baez back and relayed the requested prices.

Over the course of their investigation -- through telephone calls and text messages between Paredes, confidential witnesses, and other members of the DTO -- FBI agents connected Paredes to several drug sales, including sales of cocaine, heroin, and fentanyl. As a general matter, the heroin1 transactions that the FBI identified followed a pattern: (1) CW-6 would call Vidarte to order drugs, (2) Vidarte would call Paredes to arrange for Paredes to deliver the drugs to Vidarte, and (3) Vidarte would call CW-6 to confirm the pick-up arrangements.

1 While confidential witnesses arranged to purchase heroin from the DTO, laboratory tests revealed that the purchased substances contained a mixture of heroin and fentanyl.

During the same time, a different confidential witness, CW-5, also purchased heroin and fentanyl from the DTO through Paredes, which he would later resell. CW-5 sold large amounts of cocaine, at least 100 grams every one to three weeks, to Paredes. These cocaine sales are at the core of Paredes's appeal. In addition, the telephone call described earlier, which the FBI used to identify Paredes as a member of the DTO, reveals that Baez purchased cocaine supplied by Paredes on at least one occasion. However, the record does not reveal from whom Paredes obtained the cocaine.

In 2020, a federal grand jury returned a superseding indictment against Paredes and other individuals involved in the DTO. Paredes was charged with conspiracy to distribute and to possess with the intent to distribute heroin, cocaine, and fentanyl2 in violation of 21 U.S.C. §§ 841(a)(1), 846.3 The indictment further alleged that the offense charged involved "400 grams or more of a mixture and substance containing a detectable amount of" fentanyl and "100 grams or more of a mixture and

2 The indictment also listed cocaine base as one of the charged

substances. However, the jury instructions did not reference cocaine base because the government had informed the court that "there was no evidence that Paredes was involved in the distribution of cocaine base." And rather than listing the specific drugs involved, the jury verdict form simply listed "controlled substances."

The eight-count indictment charged Paredes 3 along with seventeen others, including Baez and Vidarte.

substance containing a detectable amount of heroin." Additionally, the indictment alleged that both substances were "reasonably foreseeable by" and "attributable to" Paredes such that statutory mandatory-minimum sentences applied to the charge, § 841(b)(1)(A)(vi) (ten-year mandatory minimum for substance containing fentanyl), (b)(1)(B)(i) (five-year mandatory minimum for substance containing heroin).

The case proceeded to trial, during which the government elicited testimony from two FBI agents involved in the investigation, CW-5, and several of the confidential witnesses who participated in controlled purchases. The government also presented transcripts of numerous telephone calls and text messages between members of the DTO, including Paredes, and between DTO members and confidential witnesses. With respect to these calls and messages, the government asked the FBI agents multiple questions about what they understood those messages to mean (e.g., asking the agents what they understood certain slang terms to mean or what they understood certain comments to be referring to).

Following the seven-day trial, the jury convicted Paredes of the one count of conspiracy to distribute and to possess with intent to distribute 1 kilogram or more of heroin, 400 grams or more of fentanyl, and 500 grams or more of cocaine in violation of 21 U.S.C. § 846. The jury additionally found that the conspiracy involved 400 grams or more of "a mixture or substance

containing a detectable amount of" fentanyl and 100 grams or more of "a mixture or substance containing a detectable amount of" heroin and that both were "reasonably foreseeable by" or "attributable to" Paredes. Other details from the trial which are relevant to the issues on appeal are discussed below.

The district court sentenced Paredes to 135 months of incarceration to be followed by 5 years of supervised release. Paredes timely appealed his conviction.

II. Discussion

On appeal, Paredes raises two claims of error: (1) that the district court erred in allowing the FBI agents to testify as to their understanding of various telephone calls and text messages, and (2) that the evidence presented at trial varied from the charges presented in the indictment. Neither is availing.
