"On the evening of the murder, around 8:30 p.m., two phone calls were made from the AIAG offices to lawyer Caracciolo di Sarno, who was the owner of AIAG, by a male individual who wanted to speak to the lawyer, who, however, claimed not to be available at that time. Therefore, there was definitely a male individual inside that building who knew the lawyer's number, and again, I don't see why Busco would have ever called lawyer Caracciolo di Sarno, whom he probably didn't even know existed."
