BOLO for "Woman infatuated with Columbine"

[crays]

Is this an orchestrated event? Let's say we dig into it. I myself have not had the time to read every story from every news outlet, so help me out here.

To my understanding, two things that have been stated are that she flew here and then, in very short order, purchased a pump shotgun.
How did she depart the airport? Are they looking at airport security footage to determine that?
Where did she purchase (legally, I might add) said firearm? Are they reviewing that security footage, provided it exists. (I'm going to go to the link above about how she was known to LE in FL already before I expound on this point further)

MOST IMPORTANTLY: How is she funding this venture? Where did that money come from? Might be some telling info if we can figure that out.

Although this is likely all being done, but we are not privy to the info during the investigation.
