Mr. Cunningham. That is correct.
Mr. Eisenberg. Did you make a test with the exhibit, with the rifle, 139, to determine whether that left a powder residue on the right cheek?
Mr. Cunningham. We did.
Mr. Eisenberg. Will you describe that test?
Mr. Cunningham. Yes; this time we ran a control. We were interested in running a control to find out just what the possibility was of getting a positive reaction after a person has thoroughly washed their hands. Mr. Killion used green soap and washed his hands, and we ran a control, both of the right cheek and of both hands.
We got many reactions on both the right hand and the left hand, and he had not tired a gun that day.
Mr. Eisenberg. This was before firing the rifle?
Mr. Cunningham. Yes, sir. That was before firing the rifle. We got no reaction on the cheek.
Mr. Eisenberg. Also before firing the rifle?
Mr. Cunningham. Yes.
