Yes, I don't recall if that girl was an escort or just someone he vaguely knew - he had been exploring the kinky world a bit. A neighbour heard him scream "No -(the woman's name) --no, don't do that!" and then some loud howls, and it turned out she had also taken his wallet after he died.
At the trial she said a Mr X had entered the place while she was making coffee, he'd have stabbed him and set fire to the place and then left again - obviously the court didn't believe that story (her fingerprints were on the bloodied knife, but no one else's) Now, as she took the wallet it could be seen as robbery & murder, but it's hard to say if it might have happend had she not been drunk too.
