Looking over the body, it seems that Chatrilon is most definitely dead. That is, unless he has the ability to survive the amount of blood loss and live without breathing. After taking away his rapier, shortbow and arrows, and the buckler strapped to his arm, Caine finds that the man has, concealed beneathe his robe and jacket, a small vial of soft blue liquid, a rolled up scroll, and a small, nondescript tube with some kind of runs along its length. He also finds the small, inverted yellow Y symbol that Chatrilon took off of one of the bodies you found earlier.
As far as Krog can tell, all is clear for the moment.
