Money??? .. that doesn't make sense ..
Huh?
This is too strange -- but then, there are reports now (see MeeknMing's posts above) that tarot cards have been found at more than one site, which suggests that strange isn't all that uncommon with this case.
I've long thought that this is a nutjob case, and that the key would be to find the movie that most closely matches the MO for this case. Now the demand for money makes me wonder if it's Denzel Washington's John Q.
More likely, though, it's some dimbulb who thought he could extort some money by writing a fake sniper note. I guess we'll know today or tomorrow, if/when the sniper strikes again.
