*408 OPINION
This case arose out of the death of Michael Kochmanowicz, ninety-one years old, whose body was discovered bound and gagged on his living room floor. The body was tied in such a fashion that the bindings included a connection between the wrist, up the center of the back to a gag. The gag passed under the tongue and forced it backward to where it blocked the passage of air through the mouth and nose. The effect was that if the deceased attempted to ease the pressure of the gag on his tongue, he would cause additional pain to his shoulder and if he attempted to relieve the pain in his shoulder by relaxing his arms, he would cause the gag to become tighter. Mr. Kochmanowicz’s death was caused by suffocation and multiple injuries of the head and trunk. 1 Appellant took a clock radio when he departed from the house.
Appellant was arrested on April 17, 1972 attempting to flee from another home in the neighborhood occupied by a 77-year old woman who also lived alone. The burglary of April 17, 1972 was committed with an accomplice who was shot by the police in their attempt to escape. 2 While in custody for the April 17, 1972 burglary, the appellant was fingerprinted and it was ascertained that his fingerprints corresponded to a print lifted from the broken second floor window of Mr. Kochmanowicz’s home. After interrogation, appellant confessed to the burglary of the home of Mr. Kochmanowicz on April 12, 1972 and to causing his death. Appellant was convicted by a jury of murder in the first *409 degree, burglary and robbery and was sentenced. Appellant appeals from the judgments of sentence. 3
The first question to be considered is whether the introduction of appellant’s confession violates the doctrine of this Commonwealth that has become known as the
McCutchen
rule. This doctrine which was first articulated in
Commonwealth v. Roane,
Before we can reach the merits of this contention we are faced with a question of whether the issue was properly preserved.
Commonwealth v. Gravely,
Trial counsel filed a boiler plate post-trial motion asserting that the verdict was contrary to law, insufficient evidence and that “the Commonwealth did not sustain its burden in proving the jurisdiction of the crime.” Although this motion contained a request to file additional reasons “as they arise,” the record reflects no effort to supplement that motion. From the trial court’s opinion disposing of post-trial motions, it appears that the involuntariness of the confession was argued, but there was no assertion that the defend *411 ant’s immaturity due to age prevented him from appreciating his rights. 4
The heart of the
McCutchen
rule is the concern that the immaturity of a minor defendant requires its added protection.
See Commonwealth v. Barry Smith,
Moreover, the
Barnes
and
Chaney
decisions providing for the retroactive application of
McCutchen
to then pending cases can in no way be construed as allowing new issues to be introduced which were not then under consideration in those proceedings. The retroactive application of
McCutchen
represented the implicit acceptance of the view that fairness dictated the applicability of the newly announced principle to all similarly situated litigants.
Commonwealth v. Hill,
*412
We next turn to the question as to whether or not under the totality of the circumstances there is a basis for concluding that the challenged statement was in fact involuntarily given.
Commonwealth v. Betrand,
Turning the attention first to his ability to comprehend and understand his rights to counsel and the protection against self incrimination, it is significant that although he was 16 years, 9 months of age at the time of the interrogation, he had previously experienced nine (9) other encounters with the law. 5 This history suggests that the custodial atmosphere was not as traumatic as it would be for one initially experiencing it and further, would have provided him with at least an acquaintance of the procedures to be *413 expected upon arrest. 6 During the instant custodial interrogation, appellant was warned of his Miranda rights on at least five (5) different occasions. Three (3) of these warnings occurred before an inculpatory statement was elicited.
Appellant’s reliance upon his asserted unfamiliarity with the language is belied by the fact that he testified in all of the proceedings in English although an interpreter was present or available on each of these occasions. Moreover, our examination of the record of his testimony in the various proceedings confirms the trial court’s finding that he had sufficient understanding of the language to comprehend what was transpiring. In addition to the written record, this court heard a tape recorded account of the third and final statement given by the appellant in response to questions put to him by the interrogating officers which further confirmed the trial court’s findings.
With regard to his Intelligence Quotient (I.Q.) of 55, the Commonwealth’s expert suggested that it did not reflect an inability to comprehend. To the contrary, the expert expressed the opinion that appellant possessed average potential and that the low testing score could be attributed to his illiteracy in the English and Spanish languages. 7 The Commonwealth offered as additional evidence to establish that the confession was knowingly made the observation of the officers who testified that appellant was able to understand their questions and to give responsive answers. From the foregoing, it is apparent there is no basis for concluding that the confession was not knowingly made.
This record also fails to demonstrate that his will was overborne. Although it is clear that ill health may well influence the will to resist,
Commonwealth v. Perry,
Next, appellant attempts to cite two instances of counsel’s ineffectiveness. First, appellant alleges ineffective assistance of trial counsel for failure to preserve the issue that his confession was the product of an unnecessary delay between arrest and arraignment.
Commonwealth v. Futch,
The record further reflects that this was not a continuous period of interrogation. A portion of the period was expended in attempts to reach members of appellant’s family
*415
for their presence during the interrogation. We must also exclude approximately two hours consumed in the administration of a polygraph test which we have previously held to be a necessary step in the investigative process when agreed to by the defendant and given promptly after that agreement.
Commonwealth v. Smith,
The second alleged instance of ineffectiveness was counsel’s failure to raise in post-trial motions the objection of prejudicial remarks made by the prosecutor. During the cross-examination of Detective Potocnak, defense counsel began questioning whether the detective properly punctuated appellant’s statement when the detective wrote it down. When trial counsel requested that the record indicate that the prosecutor was shaking his head as the questions were asked to the detective, the prosecutor replied, “I am just shaking my head because of the stupidness of the question.” Trial counsel immediately moved for a mistrial, a motion which was denied by the court below. When trial counsel argued that the prosecutor was trying to imply that he (appellant’s counsel) was stupid for asking the question, the prosecutor interjected, “It’s a stupid question.”
A mistrial is required only when an incident is of such a nature that its unavoidable effect is to deprive appellant of a fair trial.
Commonwealth v. Brown,
Judgments of Sentence Affirmed.
Notes
. It appears that the victim remained alive for several days before suffocating. The body was discovered by the decedent’s daughter on April 17, 1972.
. Although appellant consistently maintained in his confessions that he committed the crimes of April 12, 1972 alone, a co-defendant (Eldimiro Colon) was arrested and convicted of the charges. We affirmed that conviction in
Commonwealth v. Colon,
. This appeal was delayed for the following reasons: The original appeal was non prossed on July 2, 1974 for failure to file a brief. Thereafter, on January 3, 1980 new counsel petitioned to remove the non pros. We denied the petition on February 12, 1980 without prejudice to appellant’s right to seek relief under the Post Conviction Hearing Act, Act of January 25, 1966, P.L. 1580, 19 P.S. § 1180-1 et seq. (Supp. 1981-82). Appellant filed a PCHA petition seeking only an appeal nunc pro tunc. Following a hearing on June 6, 1980, appellant was granted the right to file an appeal nunc pro tunc by the PCHA court.
. The post-trial challenge to the confession consisted of complaints that physical force was employed to coerce the confession; that he was in a weakened state because of heroin withdrawal; and that his educational deficiency and unfamiliarity with the English language rendered him unable to understand the nature and import of the constitutional warnings.

. During several prior arrests, he was given his warnings and refused to make a statement.
. Appellant stated during questioning that he could not read or write English or Spanish. However, he stated he could sign his name and did sign the written confession.
. Appellant attempts to extend this time by including in the period of unnecessary delay the period of time during which he was being questioned for the unrelated burglary. This he may not do.
