Curtis is saying he got away, but is very well known to the people in that district.

They know who the shooter is?

If they know who the perp is, why isn't there an all-points bulletin by now?

[Quilla]

I sure wish someone would tell us then.

Curtis is indicating that they do, but is not saying any names for obvious legal reasons.

They're pretty sure it's Herbert. He was mentioned early on as Davis' guest. He is not the 2nd victim, who is now also dead.
