UPDATE April 2019:
The Case Against Adnan Syed documentary from HBO has shown a possible option: concrete grinding tools. The diamonds do not overlap in the harlequin pattern, though. But maybe the abstract shape we have been working from isn’t correct.
After doing additional web searching, I found a site that supplies them. It’s still not clear that this is what caused the marks, but an interesting fact: the man who found Hae’s body was known to polish/grind concrete. The private investigators are still working on this.
Here is the website if you want to look for yourself. I won’t put a photo this time.
Original theory: I found this from a company after hours searching the internet. It is the ONLY shape I found even close to matching.
This is a die cast used by this person:
You will see it near the bottom of her blog page.
The green bit at the right is the master for it from
No idea if this pattern was in existence back in 1999, but perhaps something similar did. It might be worth contacting the Sizzix company who makes this and see if they have seen anything similar or if they made this pattern back then.
Note the irregular shapes in the row above, similar to the irregularity of the marks on Hae’s body. It’s not just one of those patterns on the body. It’s a ‘string’ of them.
Anyone in the suspect list into craft or printing? Or their families?
Key word: Harlequin — which is ‘stacked’ diamonds
Maybe there’s something in this, maybe not. But there MUST be something that caused those marks as it certainly wasn’t at the burial site. The prosecution cannot wash this away as meaningless.
