What bodies are you trying to remove? A simple example (though by no means a 'complete' body removal script) to remove player bodies on re-spawn would be something like this (called once from init.sqf):
private ["_oldPlayer"];
for [ {_i = 0}, {_i<1000}, {_i=_i+1} ] do
{
waitUntil {not alive player};
_oldPlayer = player;
waitUntil {alive player};
hideBody _oldPlayer;
};
