I always assumed he just grabbed the lifeless body of some poor sap who got mauled by a sin eater or some such.

Ascians taking over living hosts doesn't seem to be their favored angle compared to them snatching up the deceased be it recently or otherwise. If it was, they certainly could've messed with us a heck of lot more if we could never be certain of who was or wasn't being controlled by them.
