OPINION OF THE COURT

Appellant, Norris Jones, was tried by a judge and jury and found guilty of murder in the second degree. Post-trial motions were denied and appellant was sen*225tenced to a term of 5 to 12 years in a state correctional institution. This appeal followed.

Appellant’s conviction arose out of the fatal stabbing of Dennis Stancko on October 8, 1971, in Erie, Pennsylvania.

Appellant first argues that his oral statement given to police officers, while he was being transported to police headquarters, was inadmissible because he was not given his Miranda warnings. We do not agree. The record reveals that when appellant was initially picked up by the police officers he was placed in the police vehicle and given his Miranda warnings. He was then asked if he had any weapons on his person, and he produced a knife, which he gave to the police officers, and stated that “it was the knife he used”. Under these facts, we find appellant’s statement to be admissible. See Commonwealth v. Powell, Pa., 328 A.2d 507 (1974).

Appellant next argues, citing Commonwealth v. Collins, 436 Pa. 114, 259 A.2d 160 (1969), that his formal statement is inadmissible because he was not informed prior to his questioning that the victim of the stabbing had died. We do not agree. When appellant was initially given his Miranda warnings at the police station, he was not informed that the victim had died because the police were unaware of the fact. After several preliminary questions, the interview was stopped because the police were informed of the death of the victim. Appellant was then readvised of his rights and told that the victim had died. He again waived his rights and gave the police a statement. This second warning given to appellant advised him of the death of the victim and gave him the requisite information to make an intelligent decision of whether to waive his rights. We therefore find no error in the police procedure.

Appellant next argues that he was denied due process of law because of the absence of black jurors on *226his jury. Appellant did not file a challenge to the general array of the jury panel prior to trial, but only raised the issue in post-trial motions. The trial judge took this issue under advisement, and defense counsel agreed that he would accept the findings as stated in Commonwealth v. Carroll, 443 Pa. 518, 278 A.2d 898 (1971), pertaining to the total population of Erie County and the percentage of blacks in the county. The trial judge found that since the jury selection process was the same in Erie County as it was in Carroll, supra, and since that system was sustained when it came under constitutional challenge in Carroll, it was still valid. We must agree with that determination. Appellant failed to prove any systematic exclusion of blacks on Erie County juries, and only suggested by speculation that evidence and testimony taken on the issue in another Erie County case would prove his contention. Appellant had the opportunity prior to trial to establish his contention and create a record to support his claim. Since he failed to do so, we must dismiss his contention.

Appellant next argues that the trial judge erred in his charge relating to self-defense, and in his explanation of the differences between voluntary manslaughter and murder in the second degree. An examination of the trial judge’s charge clearly establishes that both points were fully and properly covered by the trial judge.

Judgment of sentence affirmed.

(concurring).

I concur in the result reached by the majority and desire to set forth by reasons for affirming the judgment of sentence.

Appellant Norris Jones was convicted by a jury of second degree murder and sentenced to 5 to 12 years im*227prisonment. Post-trial motions were denied and this appeal ensued.

On October 8, 1971, appellant, age 19, and a companion were involved in a fist fight with Craig Stancko, age 16. The fight ended when Craig Stancko retreated to his home. There, he told his older brother Dennis, age 22, what had transpired. Dennis, accompanied by Craig and a friend, immediately set out for Jones’s home, apparently with the intention of avenging the beating Craig sustained.

In an effort to entice Jones out of his house, Dennis pounded on Jones’s door. When Jones opened the door, a fight began and Jones was knocked to the ground. Jones regained his feet, drew a knife and stabbed Dennis Stancko.

Stancko ran seven blocks to his home. He was rushed to a hospital where he died.

Within a half hour after the melee, the police arrived at Jones’s home. After asking appellant whether he was “involved in this incident” and receiving an affirmative reply, the police arrested Jones and a friend, ushered them into a police car and informed the suspects of their constitutional rights.1 While en route to the police station, it occurred to the police officers that they had forgotten to search appellant. One of the officers therefore asked appellant if he had anything in his pockets. Appellant produced a pocket knife and told the police “this is the knife that was used.”

Jones was taken to police headquarters, reinformed of his constitutional rights, and told that he would be questioned about the stabbing. When the interrogators *228learned of Dennis’s death, they relayed this information to Jones, and again repeated the Miranda warnings. Sometime after he was told of Stancko’s death, Jones dictated to the police a statement in which he admitted his involvement in the killing.

At a pre-trial hearing, appellant moved for the suppression of the statements made in the police car and in the police station. This motion was denied and the statements were admitted at trial.

In this appeal, Jones argues that it was error to admit the statements. He asserts that because he was not told either of Stancko’s death or of the charges lodged against him, his waiver of his constitutional rights was not “knowing and intelligent,” and was invalid. He therefore claims the statements were admitted in violation of article I, section 9 of the Pennsylvania Constitution2 and the fifth amendment of the United States Constitution.3 I cannot agree.

The theory that a suspect’s waiver of his Miranda rights is “knowing and intelligent” 4 only if he knows the nature of the incident under investigation was first suggested in the plurality opinion in Commonwealth v. Collins, 436 Pa. 114, 259 A.2d 160 (1969). Although a number of subsequent cases discussed this requirement,5 not *229until Commonwealth v. Richman, 458 Pa. 167, 320 A.2d 351 (1974), did a majority of this Court articulate clearly the elements of this doctrine.6 There we held that while “there is no need for the police to explain in detail all of the technicalities of the charges, the accused should at least know the general nature of the transaction giving rise to the charges.” Id. at 175, 320 A.2d at 355.

Under our holding in Richman, appellant’s waiver at the police station was clearly “knowing and intelligent.” The suppression court found that before Jones waived his Miranda rights, he had been informed that he was being questioned about the Stancko stabbing. In these circumstances, the accused did “know the general nature of the transaction giving rise to the charges.”

Likewise, Jones’s statement in the police car that his “was the knife that was used,” was made with sufficient knowledge of “the general nature of the transaction” to constitute a “knowing and intelligent” waiver.7 Admittedly, the police never explicitly told appellant that they were arresting him for the stabbing. Nevertheless, when the police arrived at Jones’s home, they asked him, “were you involved in this incident?”8 Jones answered that he was. Because the arrest followed so closely the *230stabbing, an eyent in which appellant never denied participating, there could be no ambiguity as to what incident the police meant. Moreover, during the trip to the police station, appellant told his friend, “We won’t be there long. All they have to do is find out whose property it was on when it happened.” While this statement is not unambiguous, it does suggest that appellant understood he was to be questioned about the event that had just occurred at his home.

On this record, the Commonwealth adequately established that appellant had a sufficient knowledge of “the general nature of the transaction giving rise to the charges” to fathom what was at stake when he waived his rights. Therefore, I agree with the majority that Jones’s waiver was “knowing and intelligent.”

Appellant asserts that the court incorrectly charged the jury on self-defense, and that two of his points for charge were improperly rejected. He also claims that when the jury requested additional instructions, the court erred in failing to give another requested point for charge. However, appellant made no specific objections to the points now assigned as error. Pursuant to Pennsylvania Rule of Criminal Procedure 1119(b),9 failure to make specific objections to the courts charge bars appellant from asserting the alleged errors on appeal.

Finally appellant alleges that the absence of blacks on the general jury panel from which appellant’s petit jury was chosen rendered his conviction invalid. Appellant admits that he failed to make a timely objection to the array. Nevertheless he claims that this failure should be *231excused because (1) he had no opportunity to observe the racial composition of the general panel and (2) because “a constitutional error of this magnitude is not waived by the failure to make a timely objection.” Appellant’s claim that he was unable to determine the racial composition of the general jury panel is clearly frivolous. His assertion that we should take cognizance of “a constitutional error of this magnitude” is nothing more than a claim of “basic and fundamental error.” In Commonwealth v. Clair, - Pa. — , 326 A.2d 272 (1974), we held “no longer will allegations of basic and fundamental error serve to enable parties in criminal matters to seek reversal on alleged errors not properly raised below.” Id. at -, 326 A.2d at 274. Therefore, that claim was waived.10

In my view, appellant advanced no ground for overruling his conviction.
