Recross-examination of Dr. Robin Cotton (part 2)

Witness: Dr. Robin Cotton
Examiner: Peter Neufeld
Called by: Prosecution • Date: Monday, May 15, 1995 • Lines: 5
Neufeld concluded his recross-examination by obtaining confirmation that the database contained two people typed like Mr. Simpson across all five loci, then stated that he had no further questions.
1 MR. NEUFELD:

Dr. Cotton, recognizing but in this case, when you calculated the frequency of the rarity of Mr. Simpson's genetic profile, you did rely on all five loci; is that correct?

2 DR. COTTON:

Yes, we did.

3 MR. NEUFELD:

Okay. And so as to the all--as to the entire--whoops. Excuse me. And so in your database, the number of people that you have typed like Mr. Simpson across all five loci were just two people; isn't that right?

4 DR. COTTON:

Across all five, yes.

KEY QUOTE
5 MR. NEUFELD:

Yes. No further questions.
