Since everyone and his brother on TV are throwing out speculations why wouldn't it be possible for an ME terrorist cell to have researched serial killers and just took on a persona to throw off LE. Wondering out loud here...
Only lookout on MoCo PD scanner channels is for a "number 2" white hispanic
or similar male in white van. No mention if witness provided lookout, but it would seem that way. ME types could be described as hispanic-looking.
I am hearing helicopters overhead...
