I am not sure about other serial killers MO, but the way these killings are happening so often, it seems that they must have some military or police training, not so much with guns, as a lot of people have guns from an early age, but moving around so easily and carefree, not even been seen one is nine outings.

If it is terrorists, then this could go on for a while, or they may just switch states.

What they are doing is keeping out of big cities where you have plenty of survalance cameras.

Dressed as a security guard perhaps. Blending in to the scenery after the crime.
