Articles related to DNA

My colleague Joe Hyde blogged last week about the Court of Appeals’ determination in State v. Tate, __ N.C. App. ___ (June 18, 2025), that the trial court did not err when it instructed the jury on a theory that was not alleged in the indictment. I’m returning to Tate this week to discuss another aspect of the Court’s holding, namely its determination that the defendant’s confrontation clause rights were not violated when an expert from the State Crime Lab testified to an opinion that was based in part on DNA test results generated by private third-party laboratory. This post will unpack the court’s analysis of that issue and will consider what it might mean for testimony by substitute analysts more generally.

What do the topics in the title of this blog post have in common? They were the focus of the students’ criminal justice presentations this week. Nine teams of students, two on each team, have been researching and preparing their presentations throughout the semester. Here are some of my takeaways from the first set of presentations.

The State of North Carolina goes to trial against Donnie Defendant, who is alleged to be the infamous “Tarheel State Killer” and charged with committing a series of brutal assaults and murders several decades ago. The state’s case depends heavily on matching DNA evidence from the crime scene to a sample of DNA taken off a cigarette butt discarded by Donnie. At trial, Special Agent Wanda Witness testifies as an expert in forensic DNA analysis for the state. After explaining the science behind PCR, STR, loci, and markers, Wanda opines that Donnie’s DNA is indeed a match to the DNA recovered from the crime scene.

Sounds like good news for the state, but what exactly does a “match” mean? And how may the significance or statistical probability of that “match” be expressed to the jury? It’s an important question, because what might sound like two similar ways of expressing the same probability can have dramatically different meanings – and possibly even be considered error on appeal.
