SOMERSET, Pa. --


The Somerset County coroner who helped identify victims of United Airlines Flight 93 has expressed surprise about a Pentagon report that says partial, incinerated remains of some 9/11 victims that couldn't be identified were sent to a landfill.

 
Forty passengers and crew died after the plane crashed in rural Shanksville.
 
 
County Coroner Wallace Miller said Tuesday the only remains that left the area were DNA samples sent to federal researchers. Samples of victims were returned, while samples from four hijackers' remains are being held by the FBI for potential military tribunals.

 
The Pentagon released a report by an independent committee asked to examine practices at the military's mortuary at Dover, Del.

 
Miller said he didn't know of any possibility of how Flight 93 remains would get to Dover.
