OK now. So two of those people murdered were corrections officers, the others were in the wrong place at the time this guy went nuts. It seems too much of a coincidence that two of those killed were officers.
One was still working, while the other had retired. They were from different facilities in the Mohawk Valley. They were killed in two different villages. It does seem strange, but so far there has been no link found between the victims and the perp, and no motive discovered for the shootings.
