If the absent witness does not reside in the state, then the affidavit must show that the witness has promised to attend and give his testimony in the event of a continuance.18

It is sufficient if the non-resident witness promises that he will appear as a witness, and which promise the defendant in good faith relies upon.19

But the court is not bound to grant a continuance to procure evidence which is merely cumulative.20

Nor will a continuance be allowed merely to procure the attendance of character witnesses, either for the good character of the accused or bad character of another.21
