Coroner John Meyer said in the autopsy report:
"A red ink line drawing in the form of a heart is located on the palm of the left hand."
But it doesn't look anything like a heart to me, and no red ink pen was ever found.
I think it could be a contusion, and appears to be in the V shape of the leg of a plastic lawn chair. If a chair was swung at JonBenet it could be a defensive wound, or she could have been held down with a chair on her hand.
I am also of the belief that a stun gun had been used on JonBenet, and the marks on her palm could be defensive stun gun burns as she gripped the business end of the gun as she wrestled with the perp to keep from being stunned. The burns would form lines as the gun's prongs moved about on her palm as she gripped it. The lines on the palm seem to be about 1 3/8 inches apart, the same distance between the prongs of a Taser brand stun gun.
