Recross-examination of Gregory Matheson (part 2)

Witness: Gregory Matheson
Examiner: Robert Blasier
Called by: Prosecution • Date: Friday, May 5, 1995 • Utterances: 11
Defense attorney Robert Blasier conducted a brief three-question recross of criminalist Gregory Matheson focused on the Grunbaum article's reference to degraded BA blood being mistyped as type B. Matheson admitted he could not say exactly how many bands the degraded sample had, and had never contacted the article's authors for clarification. Judge Ito pointedly noted that Blasier's declared 'one question' had become three.
1 MR. BLASIER:

One question.

FURTHER RECROSS-EXAMINATION BY MR. BLASIER

2 MR. BLASIER:

Mr. Matheson, in the Grunbaum article that you testified to where there's reference to one example of a BA degrading and being mistyped as a b, do you have any idea how many bands that degraded BA had?

3 MR. GOLDBERG:

Calls for speculation, asked and answered.

4 THE COURT:

Overruled.

5 MR. MATHESON:

Not exactly, no.

6 MR. BLASIER:

You can't tell whether there were two bands at the end or one band, can you?

7 MR. MATHESON:

Not unless the term "patterns" makes reference to that, but not specifically, no.

8 MR. BLASIER:

Have you ever called Dr. Grunbaum or Mr. Zajac and ask them?

9 MR. GOLDBERG:

Calls for speculation, your Honor.

10 THE COURT:

That's three. That's three.

KEY QUOTE
11 MR. BLASIER:

No further questions.

Key Quotes (2)

Gregory Matheson
Not exactly, no.
Matheson concedes he cannot confirm a key detail about the Grunbaum article he had testified to — undermining the certainty of his earlier testimony.
Lance A. Ito
That's three. That's three.
Ito dryly calls out Blasier for promising 'one question' and asking three — a light moment that also signals the court's patience is thin.

Evidence (1)

Informal
The Grunbaum article, which describes an example of degraded BA blood being mistyped as type B — relevant to ABO serology and blood evidence reliability
