Background
Melvin Lavon Shields was convicted in 2019 of two premeditated first-degree murders committed in 1988. The State’s evidence included DNA linked to Shields from the victim’s underwear, sexual-assault-kit samples, rectal swabs, and cigarette butts in the victim’s car, along with fingerprints and eyewitness testimony placing him in the car.
Before sentencing, Shields sought DNA retesting of certain evidence under K.S.A. 21-2512. The district court denied that petition because he had not alleged either untested biological evidence or a new testing method likely to yield more accurate and probative results. Shields did not appeal. In a 2021 petition, he sought retesting using “touch DNA” methods and testing of additional items he alleged had been touched.
The Court’s Holding
The Kansas Supreme Court affirmed. It first held that res judicata did not bar Shields’ second petition. Although successive DNA-testing petitions may be barred when they relitigate the same claim, Shields’ 2021 petition raised new arguments about touch-DNA testing and sought testing of additional items; the statute also permits eligible prisoners to petition “at any time” after conviction.
But Shields did not adequately allege that retesting previously tested material with touch-DNA methods would likely produce more accurate and probative results, as K.S.A. 21-2512(a)(3) requires. And, liberally construing his pro se allegations, the court concluded that testing the newly identified items could not produce noncumulative, exculpatory evidence. DNA from other people—or the absence of Shields’ DNA—on those items would not undermine the existing evidence placing Shields’ DNA on the victim, her underwear, and other items in her car. A remand under State v. Angelo would therefore be futile.
Key Takeaways
- A later DNA-testing petition is not necessarily barred when it raises materially new testing requests or legal arguments.
- A petitioner seeking retesting must specifically allege that a new DNA technique is reasonably likely to provide more accurate and probative results.
- Even under the low threshold for potentially exculpatory evidence, requested testing must tend to prove a disputed material fact.
Why It Matters
The decision distinguishes between a procedurally permissible successive petition and a substantively sufficient one. It also confirms that courts must liberally read pro se DNA-testing petitions, while still requiring a concrete connection between the requested testing and potentially exculpatory evidence.
