I found a quote early on in that one in which a state police sergeant said “I can’t say there’s not a threat to the community.”
Clearly there was, as there was a killer of two little girls on the loose, and it didn’t appear they were targeted by someone they knew.
That sort of crime, which I believe to be sexually motivated, is far different than an event like this.
I think these killers were lying in wait; this was purposeful, personal, and almost certainly an isolated event.
This was a very strong statement by law enforcement, and I think there was solid basis for it.
