¶1Dissenting Opinion by
¶2The question presented by this appeal is whether the evidence was sufficient to sustain appellant’s conviction for aggravated assault. The majority holds that it was, and finds that the statutory requirements of “serious bodily injury” and intentional or reckless action have been met. I disagree and respectfully dissent. In my view, the Commonwealth did not produce evidence sufficient to establish either the requisite intent or the occurrence of serious bodily injury. I reach this conclusion both from my examination of the trial record and from the legislature’s differentiation of assault crimes in the Pennsylvania Crimes Code, Act of Dec. 6, 1972, effective June 6, 1978, P.L. 1482, No. 334, 18 Pa.C.S. §101 et seq.
¶3The Crimes Code defines several assault offenses, three of which are relevant to this case: harassment, simple assault, and aggravated assault.
¶4The legislature has thus differentiated these assault crimes according to the seriousness of the harm done or attempted. See Pennsylvania Bar Association, Comments Relating to the Provisions of the Crimes Code 13 (1974). If an individual does no more than subject another to “physical contact,” and neither attempts to cause nor causes any injury, he would seemingly be guilty of harassment. See Belsky and Goldblatt, Analysis and Commentary to the Pennsylvania Crimes Code 55 (1974). For simple assault and aggravated assault the determinative words are “bodily injury” and “serious bodily injury.” Further, the importance the legislature attached to the type of contact and injury involved is emphasized by the great difference in the punishments provided for the three crimes.
¶5*118Since appellant was convicted of aggravated assault, the question is whether the evidence was sufficient to show that he caused or attempted to cause “serious bodily injury”, i.e., an injury either creating “a substantial risk of death” or causing “permanent disfigurement or protracted loss or impairment of the function” of Rosenzweig’s nose.
¶6Appellant’s single punch broke Rosenzweig’s nose' and blackened his eyes. The treatment of these injuries required Rosenzweig to spend three hours in the hospital. It is clear from this relatively quick release that he was not subjected to a substantial risk of death. Moreover, there was no evidence that Rosenzweig received any permanent disfigurement or protracted loss or impairment of the function of his nose. While a broken nose may entail such consequences, this court ought not to speculate whether in fact that happened here. Commonwealth v. Simpson, 436 Pa. 459, 260 A.2d 751 (1970) (conviction based wholly on suspicion or conjecture cannot stand); Commonwealth v. Feinberg, 211 Pa. Superior Ct. 100, 113, 234 A.2d 913, 919 (1967), aff’d, 433 Pa. 558, 253 A.2d 636 (1969) (“[G]uilt must be proved and not be conjectural, and cannot rest solely on suspicion or surmise.”). If evidence was available to prove permanent or protracted harm, the Commonwealth should have produced it. As the record reads now, there is not sufficient evidence to establish that appellant “cause [d] serious bodily injury.”
¶7The issue therefore becomes whether appellant “attempt [ed] to cause serious bodily injury.” An individual commits an attempt when he intends to commit a specific crime and does an act that constitutes a substantial step toward the commission of that crime. 18 Pa. C.S. §901. See generally, Commonwealth v. Crow, 303 Pa. 91, 98, *119154 A. 283, 285-86 (1931) ; Commonwealth v. Willard, 179 Pa. Superior Ct. 368, 371, 116 A.2d 751, 753 (1955). When appellant punched Rosenzweig, he committed the requisite act. In regard to intent, the Crimes Code provides: “A person acts intentionally with respect to a material element of an oifense when: (i) if the element involves the nature of his conduct or a result thereof, it is his conscious object to engage in conduct of that nature or to cause such a result. .. .” 18 Pa. C.S. §302 (b) (1) (i). Therefore, in order for appellant to have made the necessary attempt, he must have intended to cause “serious bodily injury.”
¶8Intent may be proved by direct evidence, or it may be inferred from evidence of the surrounding circumstances. Commonwealth v. Stoffan, 228 Pa. Superior Ct. 127, 149, 323 A.2d 318, 328 (1974), quoting Commonwealth v. Freeman, 225 Pa. Superior Ct. 396, 399, 313 A.2d 770, 772 (1973). There is no direct evidence that appellant intended to cause Rosenzweig serious bodily injury.
¶9For these reasons, I would not have allowed appellant’s conviction for aggravated assault to stand. However, the evidence that appellant broke Rosenzweig’s nose and blackened his eyes was, as appellant admits in his brief, sufficient to prove that he caused “bodily injury.” I would therefore have reversed the judgment of sentence, vacated the verdict of guilty of aggravated assault, and remanded with directions to enter a verdict of guilty of simple assault and to impose sentence thereon.
¶10Hoffman and Cercone, JJ., join in this opinion.
¶11. In what follows, only the pertinent parts of the definitions of these crimes are quoted.
¶12. It is interesting to note that under prior law both assault and battery and aggravated assault and battery were misdemeanors. Assault and battery carried a maximum penalty of two years in *118prison while aggravated assault and battery had a three year maximum. Act of June 24, 1939, P.L. 872, §§708 and 709, 18 P.S. §§4708 and 4709.
¶13. In fact, the only direct evidence presented on this issue was to the contrary. At trial, appellant admitted striking Rosenzweig with his fist. He explained, however, that his girlfriend had identified Rosenzweig as the man who had hit her. When asked what his intent was in hitting Rosenzweig, appellant responded: “Just hit him. You know. Don’t hit my woman no more. If I wanted to kill him, you know, probably could have beaten him to death, but I didn’t do that. I just hit him.” I quite agree with the majority, in being “unimpressed by” this testimony; in fact, I place no weight on it at all, for to credit it would not be to consider the evidence in the light most favorable to the Commonwealth.
