unless immediate danger seems apparent.
I'm not getting this 'immediate danger' thing. First - if someone was dead thats not really immediate danger. They are already dead. The danger part passedyes there was. house trashed, bad odor and door open. if you think that is normal then please tell me the area you live so i can stay far away.
Also - as someone who has spent a lot of time going in and out of people's houses I can tell you that by no means is a trashed place that smells a guaranteed case of abandonment/death. A lot of people just dont give a shit and have lost all sense of smell
