Appellant contends that the evidence was insufficient to establish that he “possessed” a sharpened screwdriver that had been discovered during a search of his prison cell. For the reasons that follow, we reverse the judgment of sentence for possession of a prohibited offensive weapon, and affirm that for possession of a weapon or implement for escape.
It is well-settled that
*402 [i]n determining whether the evidence is sufficient in law to prove that a defendant is guilty beyond a reasonable doubt of the crime or crimes charged, we must, after a verdict of guilty, accept as true all of the evidence, direct or circumstantial, and all reasonable inferences arising from the evidence upon which the trier of facts could properly have based the verdict.
Commonwealth v. Fortune,
Appellant argues first that section 5122(a)(2) of the Crimes Code requires proof of “possession.” We disagree. “Possession” is defined under the Crimes Code as “an act, within the meaning of this section, if the possessor knowingly procured or received the thing possessed or was aware of his control thereof for a sufficient period to have been able to terminate his possession.” Act of December 6, 1972, P.L. 1482, No. 334, § 1, 18 Pa.C.S.A. § 301(c). “Our cases have construed this ‘knowledge’ or ‘awareness’ element as the exercise of conscious dominion or control over the [contraband].”
Commonwealth
v.
Rambo,
“or under his control,” was added by the 1974 Amendment. This Amendment manifests a legislative awareness of the difficulties of proving constructive possession in cases arising in prisons, because of the difficulty of proving “exclusive control” or “equal access.” By permitting conviction upon proof of “control” only, the legislature avoided this difficulty.
Id.,
259 Pa.Superior Ct. at 210,
Appellant argues next that the evidence was insufficient to establish “possession” under section 908(a) of the Crimes Code. We agree. “A person commits a misdemean- or of the first degree if, except as authorized by law, he makes repairs, sells, or otherwise deals in, uses, or
possesses
any offensive weapon.” Act of December 6,1972, P.L. 1482, No. 334, § 1, 18 Pa.C.S.A. § 908(a) (emphasis added). Unlike section 5122(a)(2), section 908(a) has not been amended to permit conviction upon proof of “control” only, and thus requires a showing of possession. “Absent literal possession, the Commonwealth may sustain its burden by showing constructive possession, which requires the Commonwealth prove that the accused had the
power to control
the contraband
and
the
intent to exercise that control.” Commonwealth
v.
DeCampli,
*405 Judgment of sentence for possession of a weapon or implement of escape affirmed, and judgment of sentence for possession of a prohibited offensive weapon is reversed and appellant discharged on that offense.
Notes
Appellant was sentenced to one and one-half to three years as a result of his convictions. The lower court, upon being reminded that appellant had been convicted on two charges, indicated that it would “cross-file the other one.” We presume that the lower court intended concurrent one and one-half to three year terms on each of the charges.
See
Pa.R.Crim.P. 1406(a) (sentences presumed concurrent unless stated otherwise). When an appellant has been convicted and sentenced on more than one charge, and one of the convictions was subsequently held invalid, “the proper course is usually to vacate the sentences and remand for resentencing on the valid counts without consideration of the invalid one.”
