Here is another (mysterious) case with mysteriously missing hyoid bone (among other things), also Dr Baden was the one who seem to have tried helped the family to get closer to the truth. Horrible case by the way.

"Also suspicious to the Antonacci family was the Navys handling of their sons death.
Antonaccis family said a Navy representative came to their Long Island home saying the 22-year-old had died in a car wreck.
Later, the Navy reportedly told them he had suffered a massive aneurysm.
The family also claimed to ABC News that the Navy failed to mention that Kyles nose and been broken, as well as other signs he had been beaten.
He looked like he was tortured, his mother said.
Unconvinced by the initial autopsy, Kyle's family had his body exhumed and hired famed forensic pathologist Dr Michael Baden to examine him.
Dr Baden found that the hyoid bone - the only bone located in the throat which critical in investigations like these - was gone.In addition, photographs and x-rays of Kyles body had also disappeared.
With those key pieces of evidence missing, a conclusive cause of death is nearly impossible to determine."
