I summoned a chick and the dead smoke came up (she was already dead?). I came back after I had already looted to take the screenshot, so I'm wielding and holding all the junk she had. Everything is hers except the water pretty much

So how was I able to summon a already dead person, with their gear and stuff? I went back to summon the guy I just shot over a wall to see if I could summon him again anywhere and I couldn't. So I'm slightly confused... I'm thinking that whoever killed her broke her hf, summoned her, then didn't want the loot... But then wouldn't the body would be out and wouldn't be summonable?
