A forensic DNA expert testified on Tuesday that fingernail clippings from Laken Riley's right hand were linked to the genetic profile of Jose Ibarra, the accused killer. The testing revealed only two likely genetic profiles - those of Riley and Ibarra.
GBI crime lab scientist Ashley Hinkle explained that finding one person's DNA under another person's fingernails typically indicates some form of scratching or contact with the nail. In this case, Riley's shorter nails made accidental contact less likely.
