Caylee's Killer May Have Put Heart Sticker Over Her Mouth

A heart-shaped sticker might have been affixed to the duct tape placed over Caylee Anthony's mouth, according to the testimony of a forensic examiner in the murder trial of mom Casey Anthony. Residue in the dime-sized shape of a heart was observed on the duct tape, reports People, and the prosecution says it found similar stickers in Anthony's home.

"If you were to wear a band-aid for an extended period of time, and then take it off, there would be glue residue and debris," says the expert. "That's what this looked like, but in the shape of a heart." The remnants of the sticker vanished after FBI agents tested the tape for fingerprints—on which they found none. But the expert said that the absence of fingerprints on a body left in the woods for several months wasn't unusual. "Fingerprints are fragile," she testified. "It's not surprising that there were none." (More Casey Anthony stories.)
