No. 25-70005

Vasquez filed a prior federal habeas petition in 2006, but to no avail. Years later, in 2019, when preparing for a hearing in state court, a newly hired toxicologist discovered an inconsistency in the Toxicology Report discussed at trial. Vasquez later, in 2023, sought authorization to file a successive habeas petition, under 28 U.S.C. § 2244(b)(3)(A), raising new claims based in part on this discovery. We held that Vasquez made a prima facie showing of compliance with 28 U.S.C. § 2244(b)(2)(B) and allowed him to file his petition raising an ineffective assistance of counsel claim in the district court. Conducting its own independent review, as required by 28 U.S.C. § 2244(b)(4), the district court nonetheless concluded that Vasquez could not satisfy § 2244(b)(2)(B)’s due diligence requirement and granted the State’s motion to dismiss without reaching the merits of Vasquez’s claim. The district court granted a certificate of appealability on this issue sua sponte. Finding no error, we AFFIRM the district court’s dismissal of Vasquez’s habeas petition. I. Background On the morning of March 5, 1998, Vasquez injected himself with heroin and soon thereafter drove his girlfriend, Brenda Lopez, to work. 1 Vasquez and Brenda were both so seriously addicted to drugs at the time that they had ceased to care about much else. Vasquez, Brenda, and two children lived with Vasquez’s parents. The two children were Meagan, their four- month-old child, and Miranda, Brenda’s four-year-old daughter from a prior

_____________________ 1 The Texas Court of Criminal Appeals summarized the facts adduced at trial when it affirmed Vasquez’s conviction on direct appeal, Vasquez v. State, No. 73,461 (Tex. Crim. App. Oct. 3, 2001) (affirming conviction upon direct appeal) (unpublished), and we have previously summarized these facts as they were relevant to Vasquez’s first federal habeas petition. Vasquez v. Thaler, 389 F. App’x 419, 421–25 (5th Cir. 2010) (per curiam).

relationship. That morning, the children accompanied Vasquez to drop Brenda off; they rode in the backseat. While on the way, Vasquez became angry about having to watch the children while Brenda was at work and, as a result, being unable to obtain more drugs. After dropping Brenda off, Vasquez took the children back home. Only a few hours later, Vasquez called 911 and told authorities that Miranda was choking. When paramedics arrived, they saw that Miranda had a bump on her head, bruises on her back, and bruising around her eyes, indicating a possible head injury. She later died from her injuries. Vasquez was charged with intentionally or knowingly causing Miranda’s death by striking her on the head with his hand. Tex. Penal Code § 19.03(a)(8). As for mens rea, the State was required to prove that Vasquez acted with a conscious objective or desire to kill or was aware that his conduct was reasonably certain to cause Miranda’s death. Tex. Penal Code §§ 6.03(a)–(b), 19.02(b)(1). A. Trial At trial, the circumstances surrounding Miranda’s death were explained as follows. After Vasquez returned home with the children, he called Brenda to ask her where she had hidden the remainder of their drugs. When she refused to tell him, Vasquez became angry and unleashed his frustration on Miranda—striking her on the head, though he could not say how many times. Although he admitted to striking Miranda, he claimed that her fatal injuries came from falling off a stool. But evidence showed that there were “at least 20 to 30” “areas of contusion” on Miranda’s body—around her face, head, trunk, “and so forth.” ROA.11466. Evidence suggested that Miranda had been sexually assaulted, though Vasquez denied responsibility. Evidence was also admitted at trial demonstrating that Miranda had a lethal amount of cocaine in her system. But the medical examiner could not explain

how the cocaine got into Miranda’s system, and Vasquez denied giving Miranda drugs. To demonstrate the requisite mens rea, the State relied on evidence that: Miranda had head injuries equivalent to a high-speed vehicular ejection; perineal injuries suggestive of sexual assault; and a lethal amount of cocaine in her system, administered by Vasquez. The cocaine evidence is the focus of his successive petition. That evidence came from three sources: Dr. Backer; Dr. White; and the Toxicology Report. Dr. Backer’s laboratory performed the testing that resulted in the Toxicology Report. He explained that testing revealed that a toxic amount of cocaine was put in Miranda’s system an hour or two before she arrived at the hospital. 2 Dr. White, the Nueces County Medical Examiner, relied on the Toxicology Report and testified that he listed cocaine intoxication as contributing to Miranda’s death in his autopsy report. The Toxicology Report was also admitted at trial. 3 The jury found Vasquez guilty, and he was sentenced to death. B. Post-Conviction Challenges and Discoveries Vasquez’s initial state and federal habeas actions did not raise any issues related to the cocaine evidence. 4 In April 2015, he filed another state habeas petition after Texas enacted Article 11.073 of the Texas Code of

_____________________ 2 Dr. Backer also explained that his lab first conducts an initial screen to determine if drugs are present. Then, if drugs are present, the lab runs a confirmatory test to determine the quantity of drugs present. 3 Though Vasquez asserts that the State did not offer the report as a standalone exhibit, the record reveals that the report was admitted at trial as part of Miranda’s medical records. 4 See Ex parte Vasquez, No. WR-59,201-01, 2005 WL 287504, at *1 (Tex. Crim. App. Jan. 26, 2005) (per curiam); Vasquez v. Quarterman, No. CC-05-059, 2008 WL 859147, at *15 (S.D. Tex. Mar. 28, 2008).

Criminal Procedure, which allows prisoners to seek relief in Texas state court based on new scientific evidence. 5 Though that petition focused primarily on evidence regarding Miranda’s head trauma, Vasquez made a new discovery regarding the cocaine evidence, in April 2019, when preparing for the hearing at the trial court. Vasquez’s counsel retained a consulting toxicologist, Dr. Valentine, to review how cocaine could have gotten into Miranda’s system.
