But David is our best witness to many other things also.

The man's expression did not change as he lost what was probably his best witness.

The two best witnesses, the women in the car, were dead.

The best witnesses would not be friends or relatives who may become heirs.

Maybe the right question is: Who else would try to make the defense too scared to call its best witness?

The man who had been carrying the 10-mm Hoylbar was the best witness of the lot, and he knew little.

"I can see he'll not be telling you and him the best witness to it all."

"So you're saying that I can't use the two best witnesses to defend you?"

He could turn out to be our best witness.

His best witnesses to the immediate aftermath of the murder were in trouble.
