Forum:Bridgeport Graveyard Remains

I went to the Bridgeport Eternal Rest Graveyard, with a Kleptomaniac Sim in the daytime. I couldn't take any named graves, but I found I could take the "Remains" by dragging them. My Sim was a Ghost Hunter, so I could use "Appease Ghost". I'm assuming that these particular remains have ghosts, right? If not, then how do I steal the named ones?
