At one point, it seemed that McCauley had information that only would have come from someone in the car to hear what Hernandez was saying, suggesting that one or both were cooperating with police. At another point, it seemed that the other two men were still at large.
Regardless, it’s obvious that police know who one or both of them are. They know because McCauley said that Hernandez sent one or both of them text messages directing them to come from Connecticut to Massachusetts for the planned meeting with Lloyd. If the police have the text messages, they know the phone numbers to which the messages were sent. Which means they know the persons to whom the phone numbers belong.
Thus, it remains entirely possible that one or both are cooperating with police — and that one or both could show up in court to testify for the probable cause hearing on July, or possibly earlier if a grand jury is convened.
