Part of me believes or wants to believe the police have their suspect. No further murders have occurred. Let's hope it stays that way. The authorities just don't have enough to arrest.
I doubt it.
I think they scaled back because a) they know who did this and, b) why waste resources when their current personnel can handle it. JMO
I would guess their governor could infuse some cash from the state budget if the county needed it to investigate this case, but that's just a guess.
