DANILSON, C.J.
Kimberly Chiavetta appeals the denial of her application for postconviction relief. She argues the district court erred in rejecting her claims that her criminal trial attorneys were ineffective in not presenting evidence that her statement to police was unreliable, presenting the defense that her deceased husband injected himself with insulin and caused his own death by an overdose, and requesting a jury instruction on voluntary manslaughter.
"`[W]hen the applicant asserts claims of a constitutional nature, our review is de novo. Thus, we review claims of ineffective assistance of counsel de novo.'" Lamasters v. State, 821 N.W.2d 856, 862 (Iowa 2012) (quoting Ledezma v. State, 626 N.W.2d 134, 141 (Iowa 2001)).
"[A]ll postconviction relief applicants who seek relief as a consequence of ineffective assistance of counsel must establish counsel breached a duty and prejudice resulted." Castro v. State, 795 N.W.2d 789, 794 (Iowa 2011).
The district court rejected Chiavetta's first assertion of ineffectiveness— that counsel failed to argue her statements to police (in which she confessed having injected her husband with insulin) were not reliable—on grounds that her two trial counsel had moved to suppress her statements on grounds they were not voluntarily made. That challenge was unsuccessful in the trial court and upheld on appeal. See State v. Chiavetta, No. 05-1911, 2007 WL 1828323, at *3-4 (Iowa Ct. App. June 2, 2007). On direct appeal, we stated:
Id. at *4. We are unable to discern how her present claim differs substantively from the arguments previously rejected.
As for her claim that trial counsel did not present a defense that her husband injected himself, the postconviction court found that the defense presented was reasonable "given the evidence the State had against her." We agree. As observed in Lamasters, 821 N.W.2d at 866,
(Citations omitted.) Moreover, Chiavetta chose the strategy pursued—that she administered the doses of insulin but did not intend to kill her husband.
Finally, we, like the postconviction court, find trial counsel was not ineffective in failing to request a voluntary manslaughter instruction because factually there was no evidence to support such an instruction. See Iowa Code § 707.4 (2003) ("A person commits voluntary manslaughter when that person causes the death of another person, under circumstances which would otherwise be murder, if the person causing the death acts solely as the result of sudden, violent, and irresistible passion resulting from serious provocation sufficient to excite such passion in a person and there is not an interval between the provocation and the killing in which a person of ordinary reason and temperament would regain control and suppress the impulse to kill." (emphasis added)); State v. Thompson, 836 N.W.2d 470, 476 (Iowa 2013) (stating "`[l]esser offenses must be submitted to the jury as included within the charged offense if but only if they meet both the appropriate legal and factual tests'" (citation omitted)).
We find no reason to disturb the district court's comprehensive and well-reasoned decision. We affirm the denial of Chiavetta's application for postconviction relief. See Iowa Ct. R. 21.26(1)(b), (d), (e).
