well u can do one more thing to fade the particle away...
u can connect the particle to a ramp ....... and
when u want to blow away the body u can key the turbulance field over to time....to create an effects like body is blown out with motion like(dispersed)....and the other thing u can use....goal to drive the particle

and if u want to that particle form a character u can use....goalPP Attribute to manage particles that are immited from emitter for a perfect .....effect..

hope...this helps..!
