Near the end, I see that Cole leaves a message instructing the people in the future that it was NOT the army of the 12 monkeys who were responsible for releasing the virus.

However, Railly was the first person to realise it was Dr Peters, She then tells cole this, who immediately goes after peters but is shot dead before getting to him.

between the moment of realising it was Dr Peters, and being shot dead, Cole does not relay this information to his superiors in the future, or to anyone infac, he dies before he can tell anyone.

Therefore, HOW could the future scientist know who it was who did release the virus? how would she know it was Peters and know to get the seat next to him to obtain the sample if the only people who knew his identity were cole and railly?

sorry if this is a stupid question, but this has had me puzzled.
