Not trying to be glib here, but if that's a 77% match in whatever "API geometrics" are, what it tells me is that you'd need a 100% match. I'm no expert, but I see eyes that are completely wrong, and Gill does not have MH's distinctive cheekbones. Those things don't change with age. I'd be astonished if this were a match. But as I said, I don't have any credentials other than what I can see. While on the subject of possible matches - there was another possibility brought forward (may have been ruled out now) by the name of Matthew Prendergrast, who has been missing a long time but would be in the right age range if he were still alive. There are photos of him online, as well as a video interview with his parents. Matthew Pendergrast, still considered missing 15 years later | KATV I had to agree with many who commented that Matthew resembled but did not really look like a match for MH. But in the video interview, the elder Prendergrast (Matthew's father) looks astoundingly like MH, except for a receding hairline. Probably nothing more than a coincidence, but I really found it striking. Anyone else notice this? I'm a newbie here, so apologies if this has been discussed before.
