Perhaps Stephany was alive when Joran went for coffee, he went for coffee and she jumped in the shower; he came back while she was dressing and she opened the door to let him in because he was carrying bread and 2 cups of coffee; he took her state of partial undress to mean she was a willing sex partner. Things went down from there. And before you jump on this post, yes she very well might have answered the door not completely dressed even if she didn't know him that well. Perhaps her shirt covered her panties, perhaps she wasn't modest, perhaps she trusted him because she told him she was gay, etc.
