NCIS Season 3 Episode 16

A military ambulance carrying the charcoaled body of USMC lance corporal William Danforth Jr., a Marine who allegedly died trying in a car accident to avoid a deer, explodes. It's a cleverly staged non-accident, designed to let the medics survive, and cover up the body was not Danford's. Corporal Kenneth Merrill, his best friend since childhood, lies about a fight the previous evening, but dad Dandord is his alibi. Yet forensics come up with surprises.
