Mr. Ball.

By means of your dusting powder?

Mr. Studebaker.

By a chemical, yes. This certain print that was up there, we used this special powder for cardboard and paper. That's what it's used for.

Mr. Ball.

Now, on the 22d of November 1963, were you on duty that day?

Mr. Studebaker.

Yes, sir.

Mr. Ball.

What time did you go to work?

Mr. Studebaker.

7 a.m.

Mr. Ball.

In the morning?

Mr. Studebaker.

Yes.

Mr. Ball.

What are your hours--7 to 3?

Mr. Studebaker.

Mr. Ball.

Did you get a call to go down to the Texas School Book Depository?

Mr. Studebaker.

Yes.

Mr. Ball.

What time did you go down there?

Mr. Studebaker.

I believe we got the call about 1:05--we was down there about 1:15.

And whom did you go with?

Mr. Studebaker.

Lieutenant Day and I answered the call.

Mr. Ball.

What equipment did you take with you?

Mr. Studebaker.

We took our camera and fingerprint kits and our truck. We have a truck that is equipped with all that stuff--a station wagon.

Mr. Ball.

Each one of you had a camera, did you?

Mr. Studebaker.

No, sir; we just had one camera.

Mr. Ball.

What kind of camera was it?

Mr. Studebaker.

It's a Graflex, a 4 by 5 Speed Graflex.

Mr. Ball.

Have you had some experience in operating a camera?

Mr. Studebaker.

Yes.

Mr. Ball.

How much?

Mr. Studebaker.

Well, on this certain camera?

Mr. Ball.

Yes.

Mr. Studebaker.

About 2 months.

Mr. Ball.

But you have had photography in your crime lab work?

Mr. Studebaker.

Yes.

Mr. Ball.

For how long?

Mr. Studebaker.

Was about 2 months.

Mr. Ball.

How long have you done photography altogether?

Mr. Studebaker.

In my lifetime?

Mr. Ball.

No, as one of the assistants in the crime lab, what period of years?

Mr. Studebaker.

2 months. I went to the crime lab in October, the 1st of October.

Mr. Ball.

You did--had you done any photography before that?

Mr. Studebaker.

Just home photography.

Mr. Ball.

And the fingerprint equipment, is that the dusting powder you mentioned?

Mr. Studebaker.

Yes.

Mr. Ball.

And what else?

Mr. Studebaker.

Just anything we had in the truck. We have the truck complete.

Mr. Ball.

You have different kinds of fingerprint dusting powder for different substances?

Mr. Studebaker.

Yes.

Mr. Ball.

How many different kinds of powder do you have?

Mr. Studebaker.

Well, we have a gray powder that we use for lifting prints and use under an ultra-violet light and we have a black volcano powder that we use on white or grey surfaces, and then just recently we purchased this new powder---it's a magnetic powder. It's a new type of powder that you just use something like a pen to lift your powder out of the jar that it's in and it will lift a print off of a paper better than your regular dusting powder. It's more accurate in lifting a print than anything I have ever seen. It's a new type powder--a magnetic powder is what it is, and they have a jet black and a gray and a silver-gray and different types of powder in there that you can use on different types surfaces.
