On motion of the Commonwealth, for good cause shown, the court shall order persons charged with participating in contemporaneous and related acts or occurrences or in a series of acts or occurrences constituting an offense or offenses, to be tried jointly unless such joint trial would constitute prejudice to a defendant.
