rentiss learns from an old friend, John Cooley, that their mutual friend, Matthew Benton, just died from a heart attack. Prentiss had not seen either man in several years, both for different reasons. John also mentions that Matthew thought he was going to be killed just like "T. Valentine". In searching, Garcia does find someone matching that name in the area who recently died from dehydration. There are similarities between the two deaths but no medical rationale for tying the two together as murders. A third person in the area then dies in a similar way but again no medical indication of an unnatural death or rationale tying the death to the first two. However, Prentiss and Rossi, in particular within the team, are certain the three deaths are related and that they are indeed murders. They have to tread lightly and carefully since the families of the deceased refuse to speak to the FBI - especially Matthew's family who know, and do not like, Prentiss - and since there is no official case as the police have not sanctioned one. The investigation gets more complicated for the team when they find who they believe is the murderer.
