State v. Mendoza, 250 N.C.App. 731, 794 S.E.2d 828 (Dec. 6, 2016)

In this child sexual assault case, the defendant failed to preserve the argument that the trial court committed prejudicial error by allowing the State’s expert witness to testify that she diagnosed the child with PTSD, thus improperly vouching for the witness. At trial, the defendant did not object to the expert’s testimony on the basis that it impermissibly vouched for the child’s credibility or the veracity of the sexual abuse allegations; rather, his objection was grounded on the fact that a licensed clinical social worker is not sufficiently qualified to give an opinion or diagnosis regarding PTSD.
