evidentiary rulings by the district court at trial, and the reasonableness of her sentence. We AFFIRM. FACTUAL AND PROCEDURAL BACKGROUND This case began when Ralph Jones, an investigator with the Bureau of Alcohol, Tobacco, Firearms and Explosives (“ATF”), received a referral regarding the purchase of eight firearms by Karina Deluna from a pawn shop in Houston, Texas between September 29, 2018, and July 7, 2021. The referral reported that one of those firearms had been recovered in Mexico. The case was further referred to Special Agent Benjamin Bynog in ATF’s Houston office. Bynog concluded there were several “strong indicators of straw purchasing” in the referral. Straw purchasing is falsely stating that one is the actual buyer or transferee of a firearm while instead acquiring the firearm for someone else. 2 Special Agent Bynog, accompanied by a colleague, Special Agent Matthew McDavid, went to question Deluna at her home in Houston. This would be the first of three interviews conducted with Deluna. At no point during the three interviews was Deluna informed of her rights under Miranda v. Arizona, 384 U.S. 436 (1966). Bynog recorded the second and third interviews, and they were later introduced at trial.

_____________________ 2 When buyers purchase firearms from a licensed firearm dealer, they must fill out a portion of ATF Form 4473. Abramski v. United States, 573 U.S. 169, 172–75 (2014). ATF developed Form 4473 to implement federal statutory record-keeping and verification requirements imposed on dealers to ensure that they do not sell firearms to prohibited buyers. Id. at 173. Making a false statement on the form is a felony under 18 U.S.C. § 924(a)(1)(a). See id. at 191–193. Question 11a of Form 4473 asks: “Are you the actual transferee/buyer of the firearm(s) listed on this form?” The form cautions in bold: “Warning: You are not the actual transferee/buyer if you are acquiring the firearm(s) on behalf of another person. If you are not the actual transferee/buyer, the licensee cannot transfer the firearm(s) to you.” For the purposes of this case, straw purchasing is the false answer “Yes” to Question 11a.

The initial interview took place outside of Deluna’s home. Bynog and McDavid identified themselves as ATF agents and told Deluna that they wanted to ask her about “some suspicious firearms purchases.” According to Bynog, Deluna first explained that she had purchased the firearms for hunting but, after questioning, changed her story and said that she just “liked them” and enjoyed target practice. When the agents asked Deluna where the firearms were, she told them that the weapons were at her mother’s home and that her mother was in Colombia. Bynog ended the interview by asking Deluna to call him when her mother returned and the pair could see the firearms. Shortly thereafter, Bynog learned that another firearm purchased by Deluna had been recovered in Mexico. After an unsuccessful visit to her mother’s house to confirm her story, Bynog and McDavid decided to question Deluna once more. The second interview also took place outside of Deluna’s home. The agents attempted to be discreet in their interrogation to avoid alerting Deluna’s nearby family members to the fact that she was involved in a federal investigation. Bynog, at least, was dressed in plain clothes. The pair methodically questioned Deluna about her story, occasionally indicating disbelief at her answers and prodding her to answer differently. Deluna eventually admitted that she had purchased the firearms for her sister-in-law’s boyfriend, Chino. Deluna signed a statement to that effect, confessing that she had purchased eight firearms on Chino’s behalf and delivered them to him. Deluna was not yet arrested. As the investigation proceeded, Deluna became connected to the firearm purchases of Haley Medlin, another subject of an ATF referral. Medlin, too, had purchased a weapon that was later recovered in Mexico. In August 2022, Bynog learned that Medlin was in the process of purchasing a firearm, a Barrett .50 caliber rifle, from an online firearms dealer. ATF staked out the pick-up at a local Houston gun store.

When Medlin, along with Deluna and several children, arrived to take possession of the firearm, ATF agents followed her car back to Deluna’s home. Special Agent Bynog and his team detained Medlin in front of the residence and seized the firearm she had purchased. Bynog approached the house and had a final recorded interview with Deluna, the third interview. The agents cautioned during the interview that if Deluna was not cooperative, they could “come back and charge [Deluna] with those things” she had already “admitted,” namely, straw purchasing. At one point, Bynog warned Deluna that the agents intended to detain her, and if she was not able to have another family member take care of her two children, ATF would call Child Protective Services to watch them. At the end of the interview, Deluna admitted that Medlin had informed her that she intended to buy guns on behalf of Chino. Deluna also provided written consent for a search of her cell phone. Deluna’s phone contained a trove of evidence regarding her purchases with Medlin later used at trial. Several months later, the Government filed a two-count indictment in the Southern District of Texas charging Deluna with a violation of 18 U.S.C. § 924(a)(1)(A), which prohibits making a false statement with respect to firearms records required to be maintained by a federal firearms dealer, and both Deluna and Medlin with aiding and abetting the same. Medlin pled guilty to the aiding and abetting charge and was sentenced to one year of probation. In 2024, the Government filed a superseding nine-count indictment that charged Deluna alone with one count of conspiracy, in violation of 18 U.S.C. § 371; one count of smuggling, in violation of 18 U.S.C. § 554; and seven counts of making a false statement with respect to firearm records, in violation of 18 U.S.C.
