The instant appeal arises from appellant’s conviction for rape and related offenses following a trial without jury. Ultimately, appellant was sentenced to three to six years in prison for rape, and sentencing on the remaining charges was suspended. On appeal appellant argues: (1) That the victim was incompetent to testify because of her mental retardation; (2) That trial counsel was ineffective for failing to require the court to persevere in inquiring into the competency of the victim; and (3) That appellant was denied due process of law because the evidence failed to establish with sufficient specificity the date of the alleged rape. The relevant facts, taken in the light most favorable to the Commonwealth, are as follows.
In late August or early September, 1976, the victim, Donna, was home alone watching television in the afternoon when appellant, an acquaintance of hers, entered the home through the kitchen door. When appellant’s efforts to persuade Donna to voluntarily go with him were unsuccessful, he grabbed her by the arms and led her from the home to a neighbor’s yard where he forced her to have intercourse with him. The act consummated, he returned with Donna to her home and remained there for a few minutes before departing. According to Donna she bled profusely and vomited after the rape. When her mother returned home later, Donna reported her bleeding but did not disclose its cause because she was afraid.
Subsequently, Donna received several phone calls from appellant during which he threatened to kill her if she were pregnant. Within a week or two of the incident, Donna was watching television late at night with her sister-in-law when both women heard noises outside. Donna was visibly upset and began to cry, and when her sister-in-law inquired why she was so frightened, Donna recounted the incident and the ensuing threats. Thereafter, the instant charges were filed against appellant.
Obviously, the foregoing facts if believed by the fact-finder, in this case the judge, were sufficient to sustain the *437 verdict of guilty. The difficulty with this case is that the victim, while she was a twenty-four year-old woman at the time of the offense, had the intellectual age of an eleven or twelve year-old girl, and suffered from cerebral palsy. Consequently, her competence as a witness was immediately placed at issue, especially because she was the only witness to the crimes. At trial, Donna’s mother was called to the stand first and questioned concerning her daughter’s competence. 1 She testified that Donna could read and write, although she had some difficulty with spelling words correctly, that Donna had been educated in special schools, that Donna could function normally and did not require constant supervision, that Donna frequently attended church on religious holidays and believed in God, and that Donna could understand the nature and obligation of an oath. Furthermore, Donna’s mother testified that Donna had quite a good memory upon which her mother frequently relied. Thereafter, Donna took the stand and, in response to the trial judge’s questioning, stated that she understood the oath to mean that she was obliged “to tell the truth,” that the judge expected her to tell the truth, and she promised that she would tell the truth. At this point the Commonwealth began questioning Donna on the facts underlying the charges, and defense counsel lodged no objection to the effect that Donna’s competence as a witness had not been demonstrated. Defense counsel, however, subsequently argued in support of his demurrer that Donna’s competency was sufficiently open to question as to raise a reasonable doubt concerning appellant’s guilt. Of course, the demurrer was overruled.
With regard to the preservation of the question of Donna's competency as a witness, this case is four-square with
Commonwealth v. McKinley,
Appellant next argues that trial counsel was ineffective in failing to request further inquiry into Donna’s competence before permitting her to testify in the Commonwealth’s case-in-chief. We disagree.
The standard by which the effectiveness of counsel will be measured has been iterated and reiterated in the courts of this Commonwealth:
“[C]ounsel's assistance is deemed constitutionally effective once we are able to conclude that the particular course chosen by counsel had some reasonable basis designed to effectuate his client's interests. Commonwealth ex rel. Washington v. Maroney,427 Pa. 599 , 604,235 A.2d 349 , 352 (1967).
Our Supreme Court further explained in that case that "a finding of ineffectiveness could never be made unless we concluded
that the alternatives not chosen offered a potential for success substantially greater than the tactics actually utilized." Id.,
Finally, appellant contends that he is entitled to a new trial because the Commonwealth was not required to establish the date of the rape with greater certainty. Appellant maintains that he was thus denied due process of law under the Fourteenth Amendment of the Federal Constitution as *440 well as under Article I, Section 9 of the Constitution of this Commonwealth. Again, we disagree.
It is well-established that the Commonwealth must show the date of an alleged offense with "reasonable certainty" in order to withstand a demurrer.
Commonwealth v. Devlin,
When the foregoing considerations are weighed in the instant case, the balance tips in favor of the Commonwealth. While there was some confusion concerning the date on which the rape took place, the testimony of the victim was that the offense occurred in the summertime approximately a week before her mother's birthday. This testimony was corroborated in part by the victim's testimony that she reported the incident to her sister-in-law approximately one week after it took place, and the testimony of her sister-in-law that this conversation occurred in either the first or second week of September. When we weigh the ambiguity of the testimony concerning the date of the offense against the mental retardation of the victim and her expressed fear in promptly reporting the incident to her

we cannot conclude that the inexactitude in dating the rape was fundamentally unfair to the defendant. While it may be conjectured that the Commonwealth's failure to establish the date of the rape with precision could have precluded the defendant's proffering a credible alibi defense, because of the brevity of the incident the same could be said of the Commonwealth's failure to prove the hour of the day during which the rape took place.
Cf. Commonwealth v. Brandrup,
For the foregoing reasons, the judgment of sentence is affirmed.
