I don't tend to write up characters who don't have combat abilities or are likely to appear in a combat situation. I assume average BODY and STUN, and whatever skills make sense.  If they are shot or punched by a brick, they will go down, and die unless they receive quick medical attention.
 
(EDIT: I might write some backstory for them, but I don't stat them out.)
 

Is the limb removable?  If so a focus limitation could work.  Make it a breakable focus and it will have its own Body.
