Help??? Grease Elemental died on Sarin's coffin and now I can't get to her body

[Illy D]

So I just killed Aelis in the Sewers, along with his Grease minions. One of them dead on top of Sarin's coffin. I found her head, but I can not access her body because the minion's body is still on top of it. I tried giving Karlach Cloud Giant Strength to make her strong and maybe try to throw it, but that isn't working. Does anyone know how I can get to Sarin's body so I can give her her skull?

alt key clicking sometimes lets you click the name and open containers that you can't otherwise get at. If that fails, you may need to reload and redo the fight... there are a small number of places like this or the grym that can cause problems if they die in a stupid spot.
