FBI latent-print examiner Elizabeth Fontaine testified that adhesive in the shape of a heart was found on a corner of a piece of duct tape that was covering the mouth portion of Caylee's remains during ultraviolet testing. Fontaine examined three pieces of duct tape found on Caylee's remains for fingerprints, and said she did not find fingerprints but did not expect to, given the months the tape and the remains had been outdoors and exposed to the elements, stressing that any oil or sweat from a person's fingertips would have long since deteriorated. Though Fontaine showed the findings to her supervisor, she did not initially try to photograph the heart-shaped adhesive, explaining, "When I observe something is unexpected, I note it and continue with my examination."
