I think they ransacked the apartment before calling the cops or coroner. Stealing from the dead would suit a DUmmie.
I think the normal response would be, "Whoa, this, whatever it is (death or unconsciousness), is too big for me to handle, so I'll call the cops about it."
When one of my older brothers died in his sleep at the age of 40 (cardiac arrest) way back in 1986, the secretary in his office and his right-hand man, mystified as to why he hadn't shown up, went to his place.
And that's exactly what they did.
