To strengthen; to add weight or credibility to a tiling by additional and confirming facts or evidence. Still v. State (Tex. Cr. R.) 50 S. W. 355; State v. Hicks, 0 -S. D. 325. 00 N. W. 00; Schefter v. Hatch, 70 Hun. 597. 25 N. T. Supp. 240. The expression ” corroborating circumstances ” clearly does not mean facts which, independent of a confession, will warrant a conviction; for then the verdict would stand not on the confession, but upon those independent circumstances . To corroborate is to strengthen, to confirm by additional security, to add strength. The testimony of a witness is said to be corroborated when it is shown to correspond with the r epresentation of some other witness, or to comport with some facts otherwise known or established. Corroborating circumstances , then, used in reference to a confession, are such as serve to strengthen it, to render it more probable; such, in short, as may serve to impress a jury with a belief in its truth. State v. Guild, 10 N. J. Law, 103, 18 Am. Dec. 404.
