*274 OPINION BY PRICE, J., December 11, 1974:
This appeal comes before the court from the judgment of sentence of the Court of Common Pleas. Appellant's only argument here is that he was denied his constitutionally-guaranteed right to a speedy trial.[1] Appellant filed the proper pretrial motion to quash the indictment and there is no question that he has not waived this right. Commonwealth v. Roundtree, 458 Pa. 351, 326 A.2d 285 (1974). However, after examining appellant's contentions, we find them to be without merit and will, therefore, affirm the judgment of sentence of the lower court.
When determining whether the appellant has been denied a speedy trial, the courts of this Commonwealth apply the "balancing test" promulgated by the United States Supreme Court in Barker v. Wingo, 407 U.S. 514, 92 S. Ct. 2182, 33 L. Ed. 2d 101 (1972).[2] We examine four factors in weighing the merits of appellant's claim; (1) the length of the delay; (2) the reason for the delay; (3) the defendant's assertion of his right; and (4) the prejudice to the defendant.
If the delay has been sufficiently long, it acts as a triggering mechanism, and we must then examine the other factors to determine if the delay is justified or excused. In the present case, there was a delay of approximately three and one-half years between arrest and trial. This delay is prima facie sufficient to require an examination of the other factors.
The record indicates 31 continuances were requested and granted between November 10, 1969, and November 20, 1972. Many of these continuances were asked for or caused by the defense, and as to those caused *275 or requested by the prosecution, we see no deliberate attempt to hamper the defense.[3] Where the appellant *276 has, at least in part, caused the delay by requesting the continuances, he may not later complain that his right to a speedy trial was violated. See Commonwealth v. Jones, 450 Pa. 442, 299 A.2d 288 (1973); Commonwealth v. Meehan, 198 Pa. Superior Ct. 558, 182 A.2d 212 (1962); U.S. ex rel. Barber v. Commonwealth of Penna., 429 F.2d 518 (3d Cir. 1970).
A review of the record from the hearing of the motion to quash the indictments reveals that appellant never asserted his right to a speedy trial. As the United States Supreme Court stated in Barker v. Wingo, supra: "We emphasize that failure to assert the right will make it difficult for a defendant to prove that he was denied a speedy trial." 407 U.S. at 532. Appellant must not acquiesce in the delay, but must assert his right to a speedy trial. See Commonwealth v. Jones, supra.
The final consideration is the prejudice caused the appellant by the delay. The United States Supreme Court has identified three interests which the speedy trial right was designed to protect: (1) to prevent oppressive pre-trial incarceration; (2) to minimize anxiety and concern of the accused; and (3) to limit the possibility that the defense will be impaired. Barker v. Wingo, supra.
The record is unclear as to whether appellant's entire pre-trial incarceration was the result of the present charges. Appellant's attorney stated that appellant was confined at Dallas on another matter,[4] but *277 later stated that appellant was in jail on the present charges only. Even if we assume that appellant's entire pre-trial imprisonment was related to these charges, his sentence was computed from July 31, 1969, indicating that he received credit towards his ultimate sentence for the time he was incarcerated. Appellant was also apparently given credit for the time from August, 1971, until December 29, 1971, when he was not in prison.
From the record, it is impossible to accurately gauge the amount of anxiety and concern the accused suffered as a result of the delay. We recognize the obvious difficulties one faces when charged with a crime and imprisoned, but we are not constrained to speculate as to whether the anxiety level was sufficiently high to require the indictments be quashed.
In addition, there is no indication that the delay caused any impairment to appellant's defense. Appellant in his brief does not allege any prejudice and our independent review of the record fails to reveal any prejudice to the appellant. On the contrary, it was the Commonwealth's witnesses whose memories were darkened by the shrouds of time and were unable to make identifications. Also, there is no evidence that the delay was planned by the Commonwealth in an attempt to hinder the defense. We conclude that from the record we do not see sufficient prejudice to require the indictments be quashed.
We are aware of the recent Pennsylvania Supreme Court decision in Commonwealth v. Williams, 457 Pa. 502, 327 A.2d 15 (1974), but we feel the facts of the present case are distinguishable. Williams was represented successively by four court-appointed attorneys, *278 and his trial was delayed for three and one-half years. The court there stated that the lower court had a duty to insure that Williams' case was tried without any undue delay. However, unlike the case at bar, the Williams case, supra, indicates that there was real prejudice caused the defense by the delay, the District Attorney actively planned and participated in the delay, and Williams indicated a desire for a speedy trial by attempting to secure private counsel to expedite his trial. These distinctions make Williams inapplicable to the present case.
After weighing all of the relevant factors, we find appellant's constitutional right to a speedy trial was not violated. Judgment of sentence is affirmed.
