Any experienced criminal attorney in Maryland will tell you that the answer to this question is yes, at least in cases where the State has evidence other than the testimony of the alleged victim. In fact, in a non-domestic violence assault case that was recently decided by the Court of Appeals, Edmund v. State, the Court held that the State need not even identify the victim by name. The only requirement, according to the COA is that the victim be "substantially identified". http://mdcourts.gov/opinions/coa/2007/94a06.pdf
In the Edmund case, which incidentally I tried in the Baltimore County Circuit Court for the trial of this case, the defendant was alleged to have fired 5 shots from a handgun at nearly point blank range at a man whom the defendant claimed had been bullying him for some time. Remarkably, the victim was apparently not hit and he fled the scene. The police canvassed the area and checked the local hospitals with negative results. The police recovered the gun and shell casings and my client and his brother (a correctional officer) both gave written statements describing the incident. My client was indictment on attempted first degree murder, first degree assault and various handgun offenses.
In the charging document the alleged victim was only identified as a black male, five feet eight inches tall with a beard and a mustache. The COA held that there was simply no requirement that the victim be named or even identified beyond the vague description contained in the indictment and upheld his conviction. The good news for my client is that he was facing life in prison but I secured him a sentence of just eight years. He'll be home in four.
