Clerk

Justice Ingrid Gustafson delivered the Opinion of the Court.

¶1 David Wayne Hyslop (Hyslop) appeals from the order of the Eighth Judicial District Court, Cascade County, denying his petition for postconviction relief which was premised primarily on claims of ineffective assistance of counsel.

¶2 We restate the issue on appeal as follows:

Whether the District Court erred in denying Hyslop’s petition for postconviction relief.

¶3 We affirm.

FACTUAL AND PROCEDURAL BACKGROUND

¶4 In 2012, Hyslop was convicted of felony murder in connection with the death of a two-year old child, October Perez. He received a 100-year sentence without parole. In 2015, Hyslop filed a pro se petition for postconviction relief (PCR) alleging various allegations of ineffective assistance of counsel (IAC). Following an evidentiary hearing in which Hyslop was not represented by counsel, his petition was denied and dismissed. On appeal, the parties stipulated that Hyslop was entitled to counsel and that the matter be remanded for appointment of such and rehearing. See Hyslop v. State, No. DA 17-0078, Order (Mont. Jun. 19, 2018). Upon remand, Hyslop was appointed counsel and filed an Amended Petition reasserting his original claims1 and adding a claim that the State inappropriately failed to produce discovery by refusing to turn over evidence it gathered regarding a drug investigation it was carrying out on the residence where the child died.

1 In the Amended Petition, Hyslop asserted his prior IAC claims and revamped his coercion claim into an IAC claim asserting counsel should have sought to suppress his statements made during a police interview.

An evidentiary hearing occurred on March 19, 2024. As Hyslop’s trial counsel, Lawrence LaFountain and Vince van der Hagen, had already testified at the prior hearing and had submitted affidavits in 2016, they were not called as witnesses again. Instead, the parties elected to present only argument. At the outset of her argument, Hyslop’s counsel asked the District Court to consider the issues raised in the original and amended petitions but advised she intended to present argument “primarily” on three IAC claims which she believed had “the greatest impact on the outcome of the trial”—failure to seek suppression of Hyslop’s statements to law enforcement, trial counsel’s concession the child’s injuries were not accidental, and failure of trial counsel to hire an independent medical expert. Following the hearing, the District Court denied Hyslop’s PCR petition concluding his claims were “either procedurally barred in that they could have been raised on direct appeal, are mere conclusory allegations not supported by any facts or evidence or were the subject of competent representation by experienced counsel making tactical decisions in Hyslop’s best interests.”

¶5 On June 23, 2011, Kristy Perez, upon returning home from work, encountered her child, October Perez, in an unresponsive state and called 911. Paramedics arrived and found the child comatose and she was transported to the nearest emergency room with severe head injuries consistent with nonaccidental trauma. From there, the child was transported to the children’s hospital in Salt Lake City where she was deemed to be brain dead. Hyslop was October’s primary caretaker while Kristy worked and attended college. That evening, Hyslop was interviewed by Great Falls Police Detectives Otto and Scott.

Before any substantive questions, Hyslop was advised of his Miranda rights,2 agreed to the interview, and signed a waiver. Although Hyslop did not confess to injuring October, he suggested various theories as to how October sustained injury—including prior tripping and falling down the stairs, eating a bad hot dog, and him accidentally dropping her on the floor when trying to put her in her bed. Additional facts will be discussed as necessary to address Hyslop’s appeal issues. Claims on Appeal.

¶6 Hyslop appeals from the District Court’s denial of his PCR petition asserting in his opening brief the following IAC claims:3 1. Trial counsel was ineffective for failing to move to suppress Hyslop’s statement to law enforcement.

2. Trial counsel was ineffective by failing to share the medical records with a hired expert.

3. Trial counsel was ineffective for arguing during closing argument that the child’s death was not an accident but a result of someone else’s actions.

4. Trial counsel was ineffective by failing to allow Hyslop to testify.

2 Miranda v. Arizona, 384 U.S. 436, 86 S. Ct. 1602 (1966).

3 It is noted that in Hyslop’s initial PCR petition he asserted trial counsel to be ineffective by failing to offer text message evidence for the purpose of impeaching the State’s primary witness, Kendall Hyslop, and in his amended PCR petition, he added an IAC claim for failure to pursue the production of discovery related to an ongoing drug investigation regarding methamphetamine use at the house where October was injured. While he notes these claims in his initial briefing in this appeal, he does not specifically raise them as issues and he does not further make argument in support of these claims. As such, we consider these IAC claims to have been waived and do not consider them herein.

5. Trial counsel was ineffective by failing to challenge the State’s introduction of other crimes, wrongs, or acts evidence.

6. Trial counsel was ineffective by failing to support a motion for change of venue.

7. Trial counsel was ineffective for failing to call defense witnesses at sentencing.

8. Appellate counsel was ineffective for failing to raise “certain issues on direct appeal[.]”

STANDARD OF REVIEW

¶7 We review a district court’s denial of a petition for postconviction relief to determine whether the court’s findings of fact are clearly erroneous, and whether its conclusions of law are correct. Stock v. State, 2014 MT 46, ¶ 9, 374 Mont. 80, 318 P.3d 1053. Claims of ineffective assistance of counsel are mixed questions of law and fact that are reviewed de novo. Whitlow v. State, 2008 MT 140, ¶ 9, 343 Mont. 90, 183 P.3d 861.

¶8 Criminal defendants are guaranteed the right to effective counsel under both the United States Constitution and the Montana Constitution. U.S. Const. amend. VI; Mont. Const. art. II, § 24. This Court reviews claims of ineffective assistance of counsel by applying the two-prong test articulated by the U.S. Supreme Court in Strickland v. Washington, 466 U.S. 688, 104 S. Ct. 2052 (1984). State v. Racz, 2007 MT 244, ¶ 22, 339 Mont. 218, 168 P.3d 684. Under Strickland, a defendant must demonstrate that (1) counsel’s performance was deficient, and (2) counsel’s deficient performance prejudiced the defense such that the defendant was deprived of a fair trial. Racz, ¶ 22. To prevail on a claim of ineffective assistance of counsel, a defendant must satisfy both

prongs; “if an insufficient showing is made regarding one prong of the test, there is no need to address the other prong.” Whitlow, ¶ 11 (citation omitted).
