Mary Boyle is a famous Irish missing child: she vanished in 1977 at the age of six, while walking from her uncle’s farm to a neighbor’s home. We have a pretty good idea as to what she’d look like if she were still alive today, because she has an identical twin. However, Mary is presumed dead.
Me — well, I hope they’re right but I’m not holding my breath. I’ve seen a lot of “We’ve almost solved such-and-such ancient case!” things deflate and fade from the headlines.
