MEMORANDUM DECISION

Judge Samuel A. Thumma delivered the decision of the Court, in which Presiding Judge Paul J. McMurdie and Judge Kent E. Cattani joined.

T H U M M A, Judge:

¶1 Defendant Brandon Lujan (Lujan) appeals his convictions and natural life prison sentences for murdering his brother, M.L., his father, L.L., and his mother, I.L.1 Lujan argues that specific acts of prosecutorial error and cumulative error deprived him of his rights to due process, to present a defense and to a fair trial. Lujan also argues the superior court erred in denying his motion to preclude late disclosure of witness testimony and in denying his requested jury instructions and related motion for a mistrial. Because Lujan has shown no error, his convictions and sentences are affirmed.

FACTS AND PROCEDURAL HISTORY

¶2 Just before midnight on August 7, 2021, Lujan arrived at his parents’ home in Phoenix with his wife and two children. Once there, Lujan shot and killed his brother outside the home and shot and killed his mother and father inside the home. Lujan’s wife drove away with their two children. Lujan then apparently brought his brother’s body inside the home and left. A neighbor who heard the shots called 9-1-1, but responding officers could not locate where the shots came from.

¶3 The next day, Lujan checked himself into the United States Department of Veterans Affairs hospital, reporting that he was suffering from anger issues. Lujan was provided a room and, after speaking with several workers there, he confessed to a nurse that he had killed his family. When Phoenix Police Officers arrived, Lujan told them he shot his brother, mother and father the day before. Officers went to Lujan’s parents’ home and confirmed his parents and his brother had been shot and were dead. Lujan was arrested and indicted on three counts of first-degree murder. He has remained in custody ever since.

2 STATE v. LUJAN Decision of the Court

¶4 The case was designated complex, and the trial was continued several times, including time to determine whether a guilty except insane (GEI) defense was viable. In April 2023, the court granted Lujan’s request for evaluation related to a possible GEI defense. See Ariz. Rev. Stat. (A.R.S.) § 13-502 (2025).2

¶5 On April 30, 2024, a week before trial, the State provided a supplemental disclosure about statements made in a second interview of Lujan’s brother, T.L. T.L. indicated that when he was interviewed years earlier (soon after his parents and brother were shot) he was still in shock from their deaths. Specifically, during cross-examination, when T.L. was asked why he initially said Lujan never abused alcohol and drugs, T.L. mentioned the detectives “came to me slightly under two weeks from when my family was murdered” and he “just wanted to answer their questions because [he] had a lot [he] was dealing with.”

¶6 T.L. stated that, having thought further, and after speaking with the police, he had revealed additional information in his second interview. Among other things, T.L. told officers (contrary to his initial interview) that Lujan used methamphetamine. T.L. explained that his motivation to come forward with this new information stemmed from him remembering “the severity of [Lujan] getting away with things that he always got away with again.”

¶7 On May 1, 2024, Lujan filed a motion arguing T.L. should “be strictly prohibited from testifying to anything contained in the attached eleventh-hour supplement.” The court denied the motion, noting the disclosure was “arguably six or seven days prior to the trial date” and there was “fair time and opportunity here to prepare for and respond to even this new disclosure.”

¶8 During the 19-day trial, which began on May 6, 2024, the State presented testimony from various witnesses about Lujan’s strained relationships with his family and wife, and his previous encounters with law enforcement. The defense countered and mentioned Lujan’s alleged military sexual trauma (MST), and relied on their theory, through expert testimony, that Lujan met the GEI criteria.

3 STATE v. LUJAN Decision of the Court

¶9 Lujan moved for a mistrial, arguing that testimony by T.L. and the State’s expert, Dr. Dana Kirby, misstated the law. The court denied the motion. The court also denied Lujan’s requested corrective jury instruction, relying instead on the court’s standard final instructions. The jury deliberated and found Lujan guilty of all three counts of first-degree murder, rejecting his GEI defense for all three counts. Lujan was sentenced to natural life in prison on all three convictions This court has jurisdiction over Lujan’s timely appeal pursuant to Article 6, Section 9, of the Arizona Constitution and A.R.S. §§ 12-120.21(A)(1), 13-4031 and 13-4033(A).

DISCUSSION

I. Lujan Has Not Shown Reversible Error Resulting from Prosecutorial Error.

¶10 Lujan argues that the State engaged in numerous instances of prosecutorial error3 by “asking argumentative questions that impugned the integrity of a defense expert; attempting to mislead the jury; misstating the evidence in closing; and vouching.” “To prevail on a claim of prosecutorial misconduct, a defendant must demonstrate that the prosecutor’s misconduct ‘so infected the trial with unfairness as to make the resulting conviction a denial of due process.’” State v. Morris, 215 Ariz. 324, 335 ¶ 46 (2007) (citation omitted); see also State v. Murray, 250 Ariz. 543, 548 ¶ 13 (2021). “Prosecutorial misconduct constitutes reversible error only if (1) misconduct exists and (2) ‘a reasonable likelihood exists that the misconduct could have affected the jury’s verdict, thereby denying defendant a fair trial.’” Morris, 215 at 335 ¶ 46 (citation omitted); see also State v. Hughes, 193 Ariz. 72, 80 ¶ 32 (1998) (similar).

3 Lujan alleges several instances of prosecutorial error, which he often refers

to as misconduct. However, the Arizona Supreme Court recognized the difference between the terms and noted “courts should differentiate between ‘error,’ which may not necessarily imply a concurrent ethical rules violation, and ‘misconduct,’ which may suggest an ethical violation.” Matter of Martinez, 248 Ariz. 458, 470 ¶ 47 (2020). Given the distinction between the two, this court uses “error” throughout, given that the prosecutor’s conduct appears better characterized as alleged error. See State v. Murray, 250 Ariz. 543, 548 ¶ 12 (2021).

4 STATE v. LUJAN Decision of the Court

¶11 The standard of review depends on whether Lujan objected. See State v. Gallardo, 225 Ariz. 560, 568 ¶ 35 (2010) (citing cases).
