Which Alice?

The White Knight Couldn't Quite Remember
ANOTHER CASE "I remember another trial at which I was
present," began the White Knight. "Again there were three defendants,
and only one of them was guilty. I remember that the first
defendant accused the second defendant, but I can't at all remember
what either the second or third defendant said. I also remember
that last week I told the case to the Red Queen, and I told her
another fact which I cannot now quite remember. I either told her
that the guilty one was the only one who lied, or I told her that the
guilty one was the only one who told the truth, but I can't
remember which. But I do remember that the Red Queen was able
to solve the case." Who was guilty?
AND THIS CASE? "There was one trial about which I remember
a great deal," said the White Knight. "I remember that there
were again three defendants and that only one of them was guilty. I
distinctly remember that the first defendant accused the second
defendant, and the second defendant accused himself. Then the
third defendant either accused himself, or he accused the first
defendant, but I can't remember which.
"I told this problem to Humpty Dumpty some time ago,"
continued the White Knight, "and Humpty Dumpty asked me how
many of the three statements were true. I can't remember now what
I told him, but after I told him, Humpty Dumpty was able to solve
the case."
Who was guilty?
WHAT WAS THE FATE OF THE GOAT? "Yes, I've seen some
fine trials, very fine, very fine!" continued the White Knight. "I
remember one curious one, and I even remember who the
defendants were!"
