Since Dan and Earl contradict each other one of them must be lying. If Earl is lying then Abe is lying and so is one of Rex and Jack, which is not possible (Earl + Abe + one of Jack and Rex = 3 liars). If Earl is telling the truth, then Dan is lying. However, only one part of Dan's statement has to be false for him to be lying, if the first part is false then that means that both Jack and Rex are lying, which is impossible again (Dan + Jack & Rex = 3 liars), which means the first part is definitely true and the second part is surely false. This means that not only is the statement (one of is lying and the other telling the truth) false, but so is (both jack and rex are lying) leaving only one possibility, that they are both telling the truth.
So:
Truth-tellers:
Rex, Jack, Earl
Lairs:
Dan & Abe
So Rex says that neither Earl nor he did it, which we know is true
Jack says it was Rex or Abe, but because what Rex said was true, it cannot be Rex so Abe is the culprit.
=)
In short, Absentee is correct

You can figure out the answer using the first 3 statements only.

First of all, we prove that Abe is lying.
If Abe was saying the truth, then what Rex said was wrong. This means that Rex and Earl both stole the candy, which opposes the question.
So, if Abe is lying, then Rex and Jack are telling the truth.
According to Jack, the thief is Rex or Abe.
But, Rex is not the thief as he is telling the truth.
Therefore, Abe is the culprit.

Since when does lying mean you say the exact opposite of the truth?
