May a law enforcement officer who personally investigates, but does not observe, a vehicle crash testify as to his opinion about who was driving the vehicle? Does the answer depend upon whether the officer is qualified as an expert in accident reconstruction? The court of appeals considered those questions in State v. Denton, ___ N.C. App. ___ (June 4, 2019), decided yesterday.
The rules of thumb about expert testimony in child sexual abuse cases are (1) that an expert can’t testify that a child was, in fact, abused absent physical evidence, and (2) that an expert can testify to common characteristics or “profiles” of sexual abuse victims. A recent court of appeals case holds that even if the State doesn’t give notice of an expert’s opinion regarding victims’ characteristics, the expert has the leeway to discuss his or her own experiences with survivors of sexual abuse.
