3 N.C. App. 114
STATE
v.
James Millard SNYDER.
No. 6825SC356.
Court of Appeals of North Carolina.
November 20, 1968.
*43 T. W. Bruton, Atty. Gen., by Bernard A. Harrell, Asst. Atty. Gen., for the State.
Wilson & Palmer, by Hugh M. Wilson, Lenoir, for defendant appellant.
CAMPBELL, Judge.
The first contention of the defendant is that the trial judge erred in denying his motion for nonsuit. The mother of the child testified that while she had had sexual relations with some six or seven young men prior to the defendant, the last time had been in the month of January 1967 with Randal Snyder, the defendant's second cousin. She further testified that her last menstrual period had been 22 April 1967; that she met the defendant on 21 May 1967; that she began having sexual relations with him the following day, 22 May 1967; that she continued doing so until sometime during the month of July 1967; and that from the time she first met the defendant until her baby girl was born on 27 December 1967, she did not date or go out with any other men. The mother, who became sixteen years of age on 12 September 1967, testified that the defendant was the father of her child. There was also corroborating evidence, including a purported statement from the defendant himself that he knew he was the father of the child.
After the birth of the child and before the warrant was issued, demand for support was made upon defendant by the brother-in-law of the mother. The defendant never contributed anything to the support, and he was able to do so.
"The practice is thoroughly settled in this jurisdiction that on a motion to nonsuit, the evidence is to be considered in its most favorable light for the State, and the State is entitled to every inference of fact which may reasonably be deduced from the evidence, and contradictions and discrepancies in the State's evidence are for the jury to resolve and do not warrant the granting of the motion *44 of nonsuit." State v. Carter, 265 N.C. 626, 144 S.E.2d 826; State v. Bryant, 250 N.C. 113, 108 S.E.2d 128; State v. Woodlief, 2 N.C.App. 495, 163 S.E.2d 407.
This assignment of error is overruled.
The second contention of the defendant is that the trial judge committed error in placing two of his witnesses in custody after they had testified. The first such witness was the defendant's cousin, Randal Snyder, who testified to having sexual relations with the fifteen year old mother on several different occasions. After his testimony had been concluded the jury was excused and, in the absence of the jury, the trial judge ordered the witness taken in custody to be charged with contributing to the delinquency of a minor. The second such witness was another cousin of the defendant, Joe Snyder, who testified to having sexual relations with the fifteen year old mother in company with the defendant on the one occasion he saw her. At the conclusion of his testimony, the jury again was excused and he, too, was placed in custody. Both witnesses were removed from the courtroom prior to the return of the jury. No explanation or comment was made about their absence in the presence of the jury. The defendant did not request the return of either of these witnesses for purposes of rebuttal.
The defendant contends that other witnesses were intimidated by this action on the part of the trial judge; however, the record does not reveal such intimidation. There is nothing in the record to show that any other witness was tendered or called or that an effort was made to produce any other witness. It is not to be presumed that such additional witnesses, if any, would have committed perjury if they had been offered.
This action on the part of the trial judge did not constitute an expression of opinion in violation of G.S. § 1-180 since no doubt was cast upon the testimony of these witnesses and since their credibility was in no way impeached. The present situation is clearly distinguishable from State v. McNeill, 231 N.C. 666, 58 S.E.2d 366, and State v. McBryde, 270 N.C. 776, 155 S.E.2d 266, where, in each instance, the witness was taken into custody under such circumstances that the jury observed it.
This assignment of error is overruled.
The third contention of the defendant is that the trial judge erred in admitting testimony of Dr. Segars to the effect that the records in his office which were kept by his nurse revealed that the mother had told the nurse that her last menstrual period was 22 April 1967.
The mother testified that Dr. Segars was her attending obstetrician; that she first went to him in November 1967 before her child was born 27 December 1967; and that she told him her last menstrual period was in April 1967. The doctor was testifying as to what the records in his office showed. These records were kept by his nurse in the regular course of business and were clearly admissible. "If the entries were made in the regular course of business, at or near the time of the transaction involved, and are authenticated by a witness who is familiar with them and the system under which they were made, they are admissible." Stansbury, N.C. Evidence 2d, § 155.
The testimony of Dr. Segars was offered for the purpose of corroborating the mother as to what she had told him. On cross-examination of the mother following the admission of this testimony, she was asked:
"Q You did, I believe, tell the doctor that you had a period, told somebody, that you had one on the 22nd of April?
A Yes, sir.
Q Is that correct?
A Yes, sir."
*45 This assignment of error is overruled.
The fourth contention of the defendant is that the trial judge committed error in charging the jury:
"Upon the first issue, the Court instructs you that the reasonable period of gestation prior to the birth of a human child is approximately seven, eight, nine, nine and one-half, or ten months prior to the birth of the baby, which period of time, members of the jury, and the Court can judicially notice, is the normal period of gestation. So, the Court instructs you, members of the jury, if you should find from the evidence and beyond a reasonable doubt, the burden being upon the State to so satisfy you, that the defendant James Millard Snyder had sexual intercourse with the prosecuting witness, Pamela Duckworth, on or about the latter part of May, 1967, and within a reasonable period of gestation Pamela Duckworth gave birth to the baby, Claudia Jean Duckworth; and that the defendant is the father of the child, then in that event you would answer the first issue YES. Otherwise, you would answer it NO."
The defendant argues that since Dr. Segars testified that in his opinion the period of gestation was thirty-six weeks, it was therefore mathematically impossible for the defendant to be the father of the baby. The testimony of Dr. Segars was an expression of his opinion, and it was not binding upon the State, for as previously pointed out, "contradictions and discrepancies in the State's evidence are for the jury to resolve." The taking of judicial notice that the normal period of gestation is between seven and ten months has been sustained by the Supreme Court, and a charge to that effect was approved in State v. Key, 248 N.C. 246, 102 S.E.2d 844. The charge in the instant case is not deemed prejudicial.
This assignment of error is overruled.
The fifth contention of the defendant is that the trial judge erred in failing to define the terms "reasonable doubt" and "presumption of innocence."
There was no request for special instructions.
"The remaining exceptions are to the effect that the court in the charge used phrases such as `presumption of innocence,' `burden of proof,' `quantum' and `reasonable doubt,' but did not define or explain them to the jury. The record shows no request that these terms be defined and in State v. Browder, 252 N.C. 35, 112 S.E.2d 728, the court held that it did not constitute error to fail to define `reasonable doubt' in the absence of a request. A similar holding as to `presumption of innocence' appears in State v. Perry, 226 N.C. 530, 39 S.E.2d 460 and the same reasoning will apply to the other terms and phrases." State v. Hall, 267 N.C. 90, 147 S.E.2d 548.
This assignment of error is overruled.
The sixth contention of the defendant is that the trial court committed error in failing to set the verdict aside. For the reasons previously stated above, it was not error for the trial court to refuse to set the verdict aside. The evidence was sufficient to sustain the verdict.
This assignment of error is overruled.
The seventh contention of the defendant is that the trial court committed error in failing to permit the defendant to cross-examine the mother when she first testified. The record discloses that in order to accommodate Dr. Segars by keeping him in court as short a period of time as possible, the solicitor on behalf of the State announced at the beginning of the trial that he desired to place the mother on the witness stand for a few qualifying questions before putting the doctor on the witness stand. In the discretion of the court, this procedure was accordingly followed. The mother, who subsequently resumed her direct *46 examination and was cross-examined by the defendant, was withdrawn after the qualifying questions. The record reveals no objection on the part of the defendant, but in the instant case the trial court, in its discretion, could have followed this procedure even if there had been an objection. 7 Strong, N.C. Index 2d, Trial, § 5, p. 260. A fortiori in the absence of any objection there was no error.
This assignment of error is overruled.
A review of the entire record discloses that the defendant has had a fair and impartial trial free of any prejudicial error.
No error.
