I don't like to guess because I try to avoid speculating. It's not always possible, but I do like to try not to. I like to go with the evidence, when it's available.
I've not heard before that there was dusting of window sill and then immediately "the" knife in the knife block was dusted.
I'm not convinced of Camm's innocence and in fact I think there well may have been a situation where he hired Boney. But that's another topic for a whole nother board.
Charles Hamilton works for the Rowlett police department. His testimony on January 15th, 1997...
1 Q. Can you tell the members of the jury
2 what area you processed first?
3 A. The area I processed first was a
4 window in the garage, it had a slashed screen, the window
5 was opened slightly. An alleged point of entry or exit
6 for a potential suspect. That was the first area I
7 processed for latents.
8 Q. Okay. And just again, why did you
9 pick that as the first area to go process?
10 A. That was just a starting point. I
11 felt it was important. My sergeant felt it was important 12 enough to process immediately....
9 Q. Okay. If you would, let's start again
10 with State's Exhibit 85-A, and just tell us where you
11 actually retrieved that latent print, sir.
12 A. This latent print, in addition to the
13 others, were recovered from the window I mentioned
14 earlier in the garage with the slashed window screen,
15 open window....
6 Q. Of that window screen. Let me ask
7 you, sir: Whether or not you processed the inside
8 portion of the window screen frame?
9 A. I did, in fact.
10 Q. The top, sides and the bottom?
11 A. Yes.
12 Q. Were you able to lift any latent
13 fingerprints from the inside portion of this frame?
14 A. I was not....
1 Q. What did do you after you finished
2 processing the utility room for latent fingerprints?
3 A. I came back and worked my way through
4 the kitchen....
24 A. I don't recall.
25 Q. Okay. Do you recall right now, do you
1 recall any other items in the kitchen that you processed
2 for latent fingerprints?
3 A. Not that I recall....
Cross Examination:
5 Q. To get a print. Okay. So, after you
6 have visually inspected the object, what do you do then?
7 A. I apply a light coat of fingerprint
8 powder, in this case black powder is the agent I used to
9 process.
10 Q. Okay. And --
11 A. With a brush, of course.
12 Q. Do you brush the whole object?
13 A. You might.
14 Q. How would you decide what to brush and
15 what not?
16 A. It's just a matter of experience,
17 common sense, and gut feeling. In this case on that
18 window, I pretty much processed the whole thing because I
19 felt it might be important.
20 Q. Okay. And, you, I guess, you have
21 this dust in a little bowl or something in your kit?
22 A. It's in a container, plastic jar
23 container.
24 Q. So you take off your container and you
25 get a brush, did you say?...
7 Q. Okay. And did you process any objects
8 on the counter?
9 A. On the center island?
10 Q. No, on the -- I'm talking about the
11 right --
12 A. The sink counter?
13 Q. Yes. The sink counter. On that side
14 that has the refrigerator on it, that is generally toward
15 the garage?
16
A. Okay. I don't recall processing any
17 specific items on there. If I did, I don't remember....

He just can't seem to recall if he dusted the knives.
Then Charles Linch testified on January 20th, 1997....
3 Q. While you were there, did you ever see
4 a butcher block with some knives in it?
5 A. Yes, I did.
6 Q. Okay. What, if anything, did you do
7 with it?
8 A. At that time, nothing. It was eight
9 knives remaining in this black, wooden butcher block....
10 Q. Okay. Did you ever form an opinion as
11 to whether or not you thought this cut had been made from
12 the outside looking in or from the inside of the garage
13 looking out?
14 A. There is one microscopic finding that
15 is more suggestive of it being punched from the outside....
22 A. Now, the strand to the right of that,
23 indicates a stress puncture. If the knife goes in and
24 that is the first strand that is cut, the strand next to
25 it is experiencing the force, in my opinion, going inward
1 to the garage.
2 Q. So more suggestive of from the
3 outside?
4 A. Yes, sir....
10 Q. What sort of examinations did you do
11 with knife number 4?
12 A. I looked first with the naked eye for
13 any hairs or fibers that might be on it. And then I put
14 this knife under the stereo microscope, that is like a
15 dissecting microscope, to look for material that was
16 within the serration grooves of this knife.
17 Q. Okay. Did you find anything within
18 the serrations themselves?
19 A. Yes, sir, I did.
20 Q. What did you find?
21 A. There were some fibrous debris and
22 some gray-type debris.
Cross Examination:
2 Q. Okay. And, after you had done your
3 test, your miscellaneous test cuts, and you never did a
4 full T-cut for a test, did you?
5 A. I did a pretty long one, but not as
6 big as on the evidence screen.
7 Q. And in all of your tests, you found,
8 more or less consistent rubber particle compared to what
9 you found on the knife?
10 A. Yes, sir, I did.
11 Q. But in all of your tests, you found
12 more fiberglass rods than what you found on Number 4?
13 A. Yes, I did.
14 Q. So, in that sense, your testing was
15 inconsistent with what you found on Exhibit Number 4,
16 wasn't it?....
2 Q. So, in -- but the two tests, the
3 rubber dust is similar from the test to the knife, but
4 the fiberglass rods are dissimilar from the test to the
5 knife?
6 A. Only in the number found....
On Redirect:
3 Q. Let me ask you, when you looked at the
4 butcher block and the eight knives were still in the
5 block, correct?
6 A. Right.
7
Q. When you looked at it? Did you ever
8 find any black fingerprint powder inside the butcher
9 block?
10 A. Not inside. The only fingerprint
11 powder I observed was on the knives on either side of the
12 open slot. None of the other knives had been printed.
13 Q. Okay. The Number 4 knife that you
14 tested where you found the fiberglass and the rubbery
15 material, was there any fingerprint powder on that knife?
16 A. No, sir.

Charles Linch affidavit from July 11th, 2002...
6. On or about June 8, 1996, I received several pieces of evidence from Detective Jim Patterson. This evidence included a butcher block with eight knives. The butcher block and knives were identical to the butcher block and knives I observed on the kitchen counter at 5801 Eagle Drive, Rowlett, Texas, on June 6, 1996.
7.
At the time I received this butcher block and knives at the SWIFS Laboratory, both the butcher block itself and all the knives in it had been dusted for fingerprints. This included a serrated bread knife which I later designated as "Knife #4." This knife was located on the left end of the bottom row of knives in the butcher block.
