Thanks, Glenda. Just one correction. Nick Dellow is the one who has done the terrific research on the proximity of the houses. I found that Bix, Duncan, and Bailey all entered Davenport high school in the same term, though I don't know how closely the three were associated. (Bailey and Duncan were fairly closely associated with each other, it appears, from at least grammar school on.) I'm sure it's hard to keep track of the deluge we've been loosing.
The grand jury never reached the question of identification, I presume, since from what we can tell Preston Ivens' testimony about not wanting to put his daughter through the trial process appears to have caused the grand jury to decline to indict.
