I went through Bryn Ridge's testimony and I don't see where he testified to any "ME" markings on a tree at the crimescene. I think the media got that wrong but if you find anything else let me know
Ridge testified several times during the trial, and his March 7 testimony hasn't been transcribed yet. It's currently only available in audio form. The "ME" markings was briefly brought up during Price's cross-examination, as you can tell from this snippet I transcribed from the audio:
Q: Inspector Ridge, at the crime scene were there any drawings found on the ground or in the trees?
A: No drawings, no sir.
Q: Okay. Were there initials found on a tree near the crime scene?
A: Yes sir.
Q: Okay. And were those initials "ME"?
A: Yes sir.
Q: My client -- his birth name was Michael Hutchison. Is that correct?
A: I suspect. I'm not sure. That's what he told me, I guess.
Q: Okay. And then he later -- are you aware that he later changed his name to Damien Echols?
A: That's what I understand, yes sir.
Q: Okay, so the initials "ME" could not stand for my client's name because he's never gone by "ME" as his initials. Correct?
Mr. Fogleman: Your Honor, is Mr. Price testifying or is he asking a question?
Mr. Price: I'm asking a question.
The Court: It's kind of hard to distinguish.
Mr. Price: Alright.
The Court: Okay. Do you know what the initials "ME" stood for?
A: No sir, I do not.
Q: Did y'all do any kind of test on the tree to indicate how long the initials "ME" had been on the tree?
A: No sir.
