Nancy Louise Abernathy (“Abernathy”) appeals the district court’s denial of her petition for habeas review. Specifically, Abernathy alleges that the district court unreasonably applied Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984), in finding that her trial attorney was not constitutionally ineffective for asserting simultaneous defenses of innocence and insanity to the charge that she murdered her daughter-in-law. Additionally, Abernathy argues that because the district court denied Abernathy’s request to hold an evidentiary hearing, the record is insufficient for this Court to determine whether the district court unreasonably applied Strickland.

A court may decide an ineffective assistance of counsel claim on a trial record “when the record is adequate to assess the merits of the defendant’s allegations.” United States v. Hill, 142 F.3d 305, 308 (6th Cir. 1998). We find that the district court did not err in ruling on the habeas petition without holding an evidentiary hearing because the record was sufficiently developed, as reflected in the district court’s opinion. After carefully reviewing the record, the applicable law, the parties’ briefs, and counsels’ arguments, we are convinced that the district court did not err in its conclusions. As the district court’s opinion, which incorporates the Magistrate judge’s report and recommendation, carefully and correctly sets out the law governing the issues raised, and clearly articulates the reasons underlying its decision, issuance of a full written opinion by this court would serve no useful purpose. Accordingly, for the reasons stated in the district court’s opinion, we AFFIRM.
