last update/edit 11/2/09

In this post I will relate all direct visual evidence, gathered from different sites, relating to the circuit board fragment found in the evidence of the Lockerbie bombing. These should be official photographs and documents, mostly from the British side of the investigation. My sources are a few, but mostly websites run by Mebo, the board’s manufacturers and confusing advocates in the trial and its controversies. At the risk of accepting bad evidence, I will accept these as accurte, if not the commentary, and simply lay them out in approximated chronological order with some of the available information on them.
The fragment was allegedly first gathered by DCs Gilchrist and McColm, unseen within a piece of cloth logged in mid-January 1989 as item PI/995, “Cloth (charred).” Anomalously, the label was later changed with “debris” written right over “cloth.” In the 2000 trial, Gilchrist was asked about the overwriting; the judges found his explanations "at worst evasive and at best confusing," but found no "sinister connotation" in this (and neither do I, in particular). Note also how the date (13/1/89 as on the left side) seems faintly penciled in for "introduction in case against," and the loaction found line seems written over with invisible ink. The resolution on these is not good - here I took the full tag and a clearer zoom-in (original images page) and merged them for the best effect.

One signature on this cluttered tag seems to be Dr. Thomas Hayes [wiki] of RARDE (Royal Armament Research and Development Establishment), who analyzed this material more closely on May 12, 1989, according to his lab log (on page 51, left - r-click new window for readable view). This was the first mention anywhere of the pivotal timer fragment, as item b) at left. Reportedly, the pages following this in Hayes’ journal were renumbered, which he was unable to explain in later testimony. This could well mean this page was inserted after the fact, as widely speculated, to introduce a backdated paper trail for a later plant. It's a little sloppy to my eyes, and doesn’t add much detail to the record; there is nothing about the board other than a simple note of “a fragment of green coloured circuit board." He offers no drawing, no details. Note that the paper fragments, carefully re-sketched here (five sheets, 2 sides each, lower half of page), were identified early and given the evidence no. PT/2. The exploded electrics of items a-c, on the same page here, are "raised" collectively as PT/35 “assorted materials RECOVERED from clothing PI995.” (caps in original) I think this means 31 pieces of evidence were catalogued between these identifications allegedly noted on the same day.

The first photograph to be taken of the fateful fragment was reportedly taken, on or around September 12 1989, by Hayes, or by “RARDE photographer Heines.” according to different web pages sponsored by Mebo, the board’s confusing makers. (Hayes version, Heines version). This is three days prior to the September 15 Feraday letter (see below), leading some to suspect he took the picture then. Its acual date of capture seems to be prior to Hayes' May 12 entry, as the lumpy shape to the right of the fragment seems to be the paper fragments prior to being separated and drawn therein. The famous photo shows the shirt collar and all the evidence taken from it, with the circuit board chunk circled in red in the publicly available version. Considering the quality of blow-ups possible from this (see below) it is presumably 35mm, and not one of the "polaroids" mentioned below. (Original Image)

At left is the best blow-up of this available, from a higher resolution original than is up anywhere on the Internet. Here can be noted the “1” shaped touch pad, twin solder lines beneath this, the intact top edge, rounded corner, crumbly edges. The "etched" sideways “M" and "scratches" beneath it have been called clues of forgery, but likely are fibers of fabric like those clustered on the left side. The color of this board's coating plastic, described as green by RARDE people, and as evidently BROWN by Mebo missives, seems to me no particular color, but more precisely off-black or muted dark gray-blue with a slight greenish hue. It's probably supposed to be burnt, so green-blue seems closer than brown. (source)

Another to take a crack at this fragment was Alan Feraday [wiki] the director at the time of DERA (Defense Evaluation and Research Agency), who at some point made a study using another shot, straight on, with another view of it flipped over on its back. Using enlarged photos (“approx X 3”), perhaps photocopied on paper, he added notes around the mirror-flipped dark shapes - the following are my best reading:
"straight edge" pointing to the straight top edge.
"curved edge" pointing to curved edge
"trimmed copper" pointing to solder lines. ("track pattern on underside" added)
"Green top surface" pointing to back view.
There isn’t much resolution here to work with, but that back view is totally unique. So I used a separate layer with maxxed out contrast to pop out all details (below, right). There seems to be a small bump corresponding to the middle of the touch pad, and some roughness (fracture? bubbling?) around the edges, quite a ways in at bottom and right. Otherwise little can be seen. image source

On September 15 1989, judging by the header, Feraday sent a memo to Detective Inspector William Williamson, a counterpart in the Dumfries and Galloway police (along with the FBI, they were the official investigators). This was to explain “some Polaroid photographs of the green circuit board,” which he found "potentially most important," depending on what ID the D&G could come up with. Feraday apologized for the quality of these pictures, noting “it is the best I can do in such a short time.” Some have presumed he was sending the circled photo above, but the use of plural photographs, could mean what he sent was the analysis above, having two photos in it. It’s not entirely clear what the rush was all about or why that precluded better pictures. (source)

Following this is a long gap in the timeline of what I've sorted out, from later '89 into early 1990. Investigators analyzed the fragment (though not for explosives residue), searched for matching board patterns, and so on. According to a Mebo site, on February 8, 1990 “a needle-thin section” was removed from the evidence, apparently for forensics work, “by Mr. French from CIBA-Geigy." Four days later, the site continues,

“Mr. Roderick MacDonald, withness no. 589, had been called into Strathclyde police-station to take some photographs of an allegedly Lockerbie-recovered MST-13 timer fragment with the allocated no: PT/35 (evidence: production no:1754) According to Court-documents, the alleged MST-13 timer fragment PT/35 was at that time no longer in its orginal condition and in one piece!” (source)

For a good trans-Atlantic, Anglo-American (sorry, Scots-American) investigation, it only seems appropriate to bring in some expertise from across the pond. Investigator Paul Foot (Flight from justice, PDF, page 11) reports a July 1990 call from FBI forensic authority and political scientist James "Tom" Thurman [wiki] offering a lead to DCI Williamson on the fragment Feraday told him of. Reportedly Feraday and Williamson both went to Virginia to meet him. Although some have said this fragment was physically taken there, and the controversy recently upped with Levy’s Lockerbie Revisited video, the preponderance of testimony suggests to me, so far, that it was just a photo. I may sort it out in a separate post.

At any rate, Thurman was able to get pictures also of a captured Libyan MST-13 timer and, on June 15 as he recalls (not July as Foot reported) found a perfect match to the fragment from Scotland. He kept some photos on file to show reporters later, including a giant blow-up, heavily blue-tinted, of the fragment, perhaps MacDonald's view. This is shown alongside a comparison board with unfilled solder lines and some odd spatterings off the touch pad. (this Mebo photo seems to be the same board Thurman compared to, here in odd color, a different angle, and labeled). The image at left also is from a Mebo graphic, with the backdrop only altered by me for aesthetic reasons. (Original Image) This is the earliest view I know of showing he top sliver missing, as well as the lower right corner cut out or at least deeply scored. Otherwise, it appears to be the same piece, if perhaps a bit bluer, probably due to photo tinting. Also note, the “M” is missing, supporting the idea it was a transitory fiber since cleaned off.

I’m still vague as to when the famous trial photo below was taken. Showing evidence PT/35(b) and, apparently, the separated corner labeled DP/31, compared to model DP/347(a), an intact MST-13 timer. This might seem the photo taken by MacDonald on Feb 12, which would leave one wondering why the trip to America if they already knew what to put it alongside. It may have been after Thurman’s ID in June, as a verification with cleaner sample, and done in 3-D. Or as some have stated, this side-by-side was done by Thurman himself, with access to both real items. Whenever, wherever, and by whomever it was captured, again with intense blue tinting of the whole evidence photo. Here I’ve color-corrected to the best (app) nexus of natural whites, standard blue backdrops, and fragment plastic color. I’m not sure where this model is from, but it’s clearly different from the one Thurman used for comparison.

In the end, counter-claims aside, the fragment looks the same throughout, other than the noted diminishings, so if any planting happened it was at the beginning, which could be later than the paperwork suggests. But the case was made and handed to us thusly: this was from the wreckage, near the bomb, perhaps part of it. It was handled carefully by trained and diligent professionals leaving a clear paper trail. It was rigorously matched, with photos AND microscopes, to a style used by Libyan operatives. And it all came down to a fragment of circuit board, and wound up appealing to the kind of late-90s popular TV fiction mentality needed to win crucial public/political support for the indictment. As agent Thurman bragged to the TV news just after the 1991 indictment, "when that identification was made, of the timer, I knew that we had it." Whether by accident or staging, it was brilliant theater.

A CHIP OFF THE OLD BOARD AND A CHIP OFF OF THAT
[Pan Am 103 Series]

Last update 10/22

Among the evidence used to implicate Libyan al Megrahi for the bombing of Pan Am 103, the strongest, most tangible, most sciencey, is the small but identifiable fragment of timer circuit board though by some to have triggered the bomb that brought the plane down on Lockerbie Scotland in December 1988. What we know is the style is the same, circuit-wise, as a MST-13 board, made by a Swiss company, Mebo, in a limited run of 20 (plus three prototypes) for Libyan intelligence in the mid-1980s. Notwithstanding the likelihood of anything surviving the reported type of explosion, fact is little is alleged to survive, and I will proceed on the notion that it's possible for this to be genuine, but far from a foregone conclusion.

In the course of a discussion thread started at the JREF forum by member Rolfe, examining whether the timer fragment was planted, I was able to establish some visual patterns helpful to understanding the issue. There are already numerous documented, eyebrow-raising anomalies with how this historic evidence has been handled and by whom, and I will address these elsewhere - here I hope to just make a quick post to convey, mostly with pictures, what I thought might be an important piece of new information I discovered looking at some jpeg images, available online and purporting to be genuine trial-related evidentiary photos. One may note a color shift from the first to view to the last, with an original faintly blue-tinted gray later showing as tinted blue all over the image. The board's color is referred to by all who speak of it as "green." The shape and layout of the fragment as seen in each photo, however, remains consistent enough, steadily holding the known shape of Mebo's MST-13 board.

< The first, chronologically, shows a battered collar from a "Slalom" brand shirt, from which were supposedly removed some fragments, the interesting one of which is visible, blown-up, at left. This poster is annotated, in Dutch it seems, and attributes this photo to Dr. Thomas Hayes, RARDE scientist, on September 12 1989. For convenience, I'm using this to identify the shot.

> The next is a file photo shown on ABC News in Nov. 1991 by FBI agent James "Tom" Thurman. This was presumably taken at the time of his June 15 1990 identification of the fragment as from a MST-13. There is plenty of confusion also as to whether he actually inspected the fragment or a photo of it, but here I'll just share his publicized hard copy, stretched to the same proportions as the exhibit photo (below), from Gideon Levy's totally amazing (but partly Dutch) Lockerbie Revisited video. Note the deep cuts, meeting at a right angle in the lower right of the touch pad. This does not seem to be present in the older photo.

< Exhibit PT35(b) photo - it's unknown at what time this was taken, but probably sometime around mid-1990. This is the most commonly seen view, as it clarifies just how open-and-shut the case is. Case being, does this dubious fragment match a board style similar to one usually made by... etc. The comparison model is reportedly an intact MST-13 confiscated from another Libyan intelligence agent, who had been planning some different bombing. It's supposedly just these two items side-by-side that allowed agent Thurman to make the connection.

Dr. Ludwig De Brackeleer, however, as a minor point of a detailed article largely about the fragment, disagreed:

There is a small glitch... It is obvious that the fragment PT35(b) does not come from one of the 20 machine-made MST13 timer delivered to Libya. The location of the T shaped touch pad, its absolute and relative dimensions do not match. Moreover the curvature of the fragment round edge equally differs!

< I took the corner from the intact board in PT35(b) into Photoshop and applied the 'trace contour' filter. Beneath this I scaled a blowup of the fragment until the "1" shaped touch pad and as much as possible matched. It's quite a perfect fit in fact, minus a missing top portion, in addition to missing sections left, right, and below - not too surprising.

What I do find interesting is, well, this:

The earlier view is lacking the right-angle cut marks marking the lower right quadrant, and the later one is lacking the top portion straight across. Why on Earth would the top portion of a piece of evidence just go missing, and why would someone hack lines across it like that?

I had my own elaborate thoughts about some renegade scientist who smelled a rat swiping a chunk to hold as blackmail, using a safe deposit box and a team of Swiss lawyers, and was trying to tie in both the Mossad and an elaborate car chase through the plazas of Rome. Before I got this far however, JREF member Dan O, who seems to know a lot about electronics and investigations, offered a more plausible explanation:

In order to examine the cross section of the piece for identification of the material, it must be cleanly cut through a good part of the board. They need to make two cuts at right angles to map the orientation of the fibers in the epoxy board. Obviously some of the documentation for this chip is not present or this would have been explained. link

That the gouges are deep into the board is evident looking at the middle view, Thurman's file photo. The portion above the horizontal slice is definitively darker than the section below, indicating slightly different planes catching the light differently. The board is either bent or completely cut through there. Where the vertical slice crosses the solder lines at bottom, it seems the solder was pulled along into a short connecting line. This is only hinted at in the later exhibit photo but quite pronounced in Thurman's picture. Below is a closer view, shown on 60 Minutes in 1999.

The missing top is a little more problematic. Dan O. seems to think a cross-section examination or something of that sort might explain the decapitation, but agreed with me that it's unusual to not present the evidence as whole as possible, with cut off parts either put back in or near their original places. Mebo's in-house designer of the MST-13 Ulrich Lumpert, In his highly unusual 2007 affidavit, mentioned a fragment cut up and presented as evidence. Lumpert claims he handed a non-operational brown-base prototype board to Swiss investigators for the Lockerbie investigation, and the next time he saw it was as the green/blue exhibit PT35(b) after it "had been sawed into two pieces apparently for forensic reasons."

Originally I had taken this to mean one small piece (the fragment) was presented, with the other piece (most of the board) chucked or whatever. However I'm now seeing a missing piece even of the small piece, and Mebo's "it was a fraud!" page seemed to be hinting at it when their site said the fragment itself, not the whole board, "was sawed into two parts in Scotland for forensic reasons." They specify that both were shown as evidence; "The large piece was given the police no. PT/35(b) and the smaller one was given the no. DP/31(a)." Looking back at the exhibit photo, it's got the label DP31 off to the side, right next to 35(b). Is the severed top shown off to the right, cropped off here along with the (a)? Mebo's take actually seems more on-target here after all. They seem to have decided it refers to the totally cut free lower-right corner section. The label does indeed point to that sector of the board, although it seems strange to log this as a separate piece of evidence, and it still leaves the top just gone.

The funny thing about this is, the Fraud page suggests first a full substitution - the forgers cut up Lumper's sample, as the original "brown" chip in the circled photo. Apparently they cut around the sideways letter "M" Lumpert scratched into it next to the "1" touch pad, to make sure he could recognize it later. In reality thisis more likely a fabric fiber like those hanging on the side, or perhaps some other illusion. But by Mebo's reckoning It wasn't til later that the perps realized it should be green, and this was after they'd cut up the brown one for "forensic reasons." In the exhibit photo "the larger piece," PT35(b), "was replaced with a green duplicate MST-13 fragment," carefully milled to mimick the original brown fake. This is known not so much by the color as the simple fact that "it can be clearly seen that no letter “M” was carved into it!" Oops! And for no particular reason I can discern, they decided the corner piece DP31(a) was actually from the brown original fake swapped back in to the swapped-out second replacement fake. Apparently they painted that section blue before fitting it in, so it would not stand out, since it doesn't. But you can't fool its designers, no! They see through any ruse no matter how imaginary it might be!

And nowhere in there, at least in graphics or English, did they make note of the missing top section as a glaring difference between the two fragments. For my part, I don't know what to make of it, and am willing to let it go as duly noted.
