FBI hair and fiber expert Douglas Deedrick is sworn in as a People's rebuttal witness. Marcia Clark uses the opening of his direct examination to establish his general expertise in fabric analysis — including fabric matching, physical reconstruction of torn fabric, and determining weapon type from fabric damage patterns — before the proceeding ends with a sidebar request.

DIRECT EXAMINATION BY MS. CLARK

8 MS. CLARK:

Agent Deedrick, you've previously testified in this case as an expert with regard to hair and fiber comparisons that you made in this case, correct?

9 MR. DEEDRICK:

That's right.

10 MS. CLARK:

Now, you also testified regarding the fabric samples you received from the victims in this case, correct?

11 MR. DEEDRICK:

That's right.

12 MS. CLARK:

Do you have any experience or have there been many cases in which you've examined--you've--there have been many cases that you've been involved in, sir, that cause you to do fabric analysis in the FBI laboratory in the past?

13 MR. DEEDRICK:

Right. Fabric analysis is very common because it's the type of material that is submitted for examination most of the time, whether it's fabric damage where you have to reconstruct pieces of fabric or determine what type of material, a knife or a bullet or a club or some other type of instrument may have caused the damage to the fabric. Fabric is examined for the presence of fiber composition and also design construction. So fabric is commonly examined in our unit.

14 MS. CLARK:

Have you done any work to establish--to do fabric matching?

15 MR. DEEDRICK:

Well, fabric matching is another type of exam that's done where fabric may be recovered from a victim such as the bindings or wrappings around the hands of a victim found at a crime scene, and that fabric might need to be compared with pieces of fabric left in the suspect's car or found in the suspect's residence. He may have stripped off pieces of a bed sheet or a pillow case so that he could prepare bindings for the victim. In so doing, in tearing that fabric, each tear is unique so that it's possible to physically match the piece of fabric from the victim or from the crime scene with the piece of fabric taken from his own residence.

16 MS. CLARK:

Have you ever done any work to determine fabric damage to determine the kind of weapon that made the damage?

17 MR. DEEDRICK:

Well, fabric damage is important as well. When the question is, could this particular knife have caused or this particular weapon have caused the damage in the fabric, again, it may be used--this type of work may be used in conjunction with the fiber comparison. That is, if you find fibers on the knife that exhibit the same characteristics as the fibers from the victim's own clothing, then you can use that information coupled with the type of damage that that fabric has incurred. You can determine if it's a single bladed knife, double-edged knife, the size of the knife. These are determinations that can be made. And, again, there's some flexibility there because there's actions involved in stabbings for instance.

18 MS. CLARK:

Could we approach, your Honor, already?
