Flashlight

A flashlight was found on the kitchen counter.

The drawer in which John Ramsey's flashlight was usually kept was open, with no flashlight inside.

The Ramseys denied putting the flashlight there.

Found in the kitchen where none of the Ramseys admitted putting it. They initially claimed to recognize it but then said they didn't. Alleged to fit the dimensions of the skull fracture.

Murder weapon?
"Dr. Werner Spitz, the forensic pathologist, even ran macabre tests to see if the heavy flashlight could have inflicted the kind of massive skull fracture that was found on JonBenÃ©t. To do so, a child’s cadaver was obtained so he could strike the skull with a similar flashlight and examine the resulting injury pattern. He said the results were consistent, that the damage could have been caused by the flashlight—but it could also have been caused by other things."
