Update: Something brewing out there

I had posted two days ago about an unusually large number of pre-paid cell phones being purchased with cash in Missouri.

Now this - from Russia Today:

Theft of dozens of propane tanks, purchase of 150 prepaid cell phones in Missouri puts FBI on alert
The FBI has launched an investigation after 150 prepaid mobile phones were bought from local Walmarts in Missouri. This comes after the theft of dozens of propane tanks in the area.

A bit more:

Further to the mobile phone scare, agents are now drawing a connection to the disappearance of dozens of tanks of highly flammable propane gas around locations in Missouri. This elevates the possible connection to a potential terrorist plot, as the local mood seems to indicate.

And it's a good number of tanks too:

The first theft was reported at the end of November by a BP gas station in Lee’s Summit. At least 18 propane tanks were stolen from the cages situated outside. Later that night, another gas station in the area reported the same story. Two weeks after that, 28 tanks were stolen from a gas station in Independence.

Sixty four tanks? That would make a big ka-boom... Cell phones for both communications and to remotely detonate any explosion. They like to use TATP - dangerous stuff but pretty easy to make with common chemicals.
