M. Tullius Cicero Pro A. Cluentio 36

[36]
  What more shall I say? How notorious, while the fact was recent, was the murder of Asinius of Larinum , a wealthy young man! how much talked about in every one's conversation! There was a man of Larinum of the name of Avilius, a man of abandoned character and great poverty, but exceedingly skillful in rousing and gratifying the passions of young men; and as by his attentions and obsequiousness he had wormed himself into the acquaintance of Asinius, Oppianicus began forthwith to hope, that by means of this Avilius, as if he were an instrument applied for the purpose! he might catch the youth of Asinius, and take his father's wealth from him by storm. The plan was devised at Larinum ; the accomplishment of it was transferred to Rome . For they thought that they could lay the foundations of that design more easily in solitude, but that they could accomplish a deed of the sort more conveniently in a crowd. Asinius went to Rome with Avilius; Oppianicus followed on their footsteps. How they spent their time at Rome , in what revels, in what scenes of debauchery, in what immense and extravagant expenses, not only with the knowledge, but even with the company and assistance of Oppianicus, would take me a long while to tell, especially as I am hurrying on to other topics. Listen to the end of this pretended friendship.
