STATE of Nebraska, Appellee,
v.
Richard V. KEITH, Appellant.
No. 38568.
Supreme Court of Nebraska.
January 19, 1973.
*501 Frank B. Morrison, Sr., Public Defender, Stanley A. Krieger, Asst. Public Defender, Omaha, for appellant.
Clarence A. H. Meyer, Atty. Gen., Harold S. Salter, Deputy Atty. Gen., Lincoln, for appellee.
Heard before WHITE, C. J., and SPENCER, BOSLAUGH, SMITH, McCOWN, NEWTON, and CLINTON, JJ.
NEWTON, Justice.
The defendant was convicted of burglary. All assignments of error are based on the admission of evidence in rebuttal pertaining to checks made for fingerprints. We affirm the judgment of the district court.
On direct examination, the prosecution did not introduce any evidence regarding fingerprints or attempts made to lift fingerprints at the scene of the crime. It was brought out on cross-examination of prosecution witnesses that the premises burglarized had been examined for fingerprints. There was no testimony on this subject by defense witnesses, but, in rebuttal, the State introduced evidence regarding the lifting of fingerprints at the scene of the crime, their subsequent examination, and the conclusion of experts that due to smudging and overlaying, it was impossible to determine whether they were or were not prints of the defendant. The names of two of these witnesses had not been endorsed on the information.
It would appear that the prosecution had knowledge of the reference to fingerprints in ample time to have introduced this evidence in its case-in-chief. It does not appear to be proper rebuttal evidence. We recognize, however, that the trial court may in its discretion permit the introduction of evidence in rebuttal that is not strictly rebuttal evidence. See, § 29-2016(4), R.R.S.1943; State v. Howard, 184 Neb. 461, 168 N.W.2d 370.
Section 29-1602, R.R.S.1943, requires the endorsement on the information of the names of witnesses for the State, other than rebuttal witnesses. The purpose is to inform the defendant of the names of persons who will testify against him and give him an opportunity to investigate regarding their background and pertinent knowledge. If the testimony of unendorsed witnesses is not damaging to the defendant, there can be no prejudice. In the present instance, the testimony objected to did not in any manner tend to show defendant's guilt. On the contrary, it indicated that no evidence of his guilt could be adduced by reason of fingerprints. Such evidence is essentially immaterial and neither harmful nor beneficial to either party. The failure to endorse on the information the names of witnesses called by the State is not grounds *502 for a reversal of conviction in the absence of prejudice. See, Waite v. State, 169 Neb. 113, 98 N.W.2d 688; State v. Adels, 186 Neb. 849, 186 N.W.2d 908.
No reversible error appearing, the judgment of the district court is affirmed.
Affirmed.
