Selecting "Attorney Name" instead of "Party Name" indicates that the only attorney appearing for the above cases is "Commonwealth Attorney."
The not-so-subtly insinuation that something is strange about this is mitigated by a simply knowledge of how the process works:
http://www.courts.state.va.us/courts/circuit/handbook_grand_jurors.pdf From the VA Handbook for Grand Juries (linked above for those who want to understand how things happen and what it all means):
The Grand Jury does not hear both sides of the case and does not determine the guilt or innocence of the accused person. This is determined by a "petit (trial) jury" if and when the accused is tried later. The Grand Jury only determines whether there is probable cause that the accused committed the crime and should stand trial.
(b)
Bills of Indictment. After a case has been certified to the Circuit Court [by a judge], the Commonwealth's Attorney will prepare a written document called a "bill of indictment," in which the accused is charged in a legal and formal manner with having committed a specified felony.
As will be described in greater detail later in this handbook, it is this "bill of indictment" that the Regular Grand Jury considers to determine if probable cause exists to require that the person accused stand trial at a later date in the Circuit Court.
