Ok, let us assume that literal cultists have summoned a literal monstrosity, and literal monstrosity has literally torn them to literal pieces, and then vacates the premises. Morning shift walks in, sees the carnage, calls the police. How soon would the forensics team get there after the responding officers? How would they respond to 4-5 bodies torn to pieces? Where would they start, what would they do?
Alright @ coronalthoughtejection . First off- wow that is a lot to take in just as a mental image. Unfortunately my response will also be based on some assumptions and varies greatly depending on where exactly in the world your cultists are summoning monsters.
In a backwoods, small town kind of setting, a forensics team may take up to 12 hours to arrive. Even considering the fact that there would be some hussle due to the eviscerated bodies, you could still be looking at 6 or more hours. The scene would not be empty during this wait period though- the responding departments officers would begin to document and may even begin evidence collection without the Forensic Team. Many small police departments, like what would be responding if this happened in an out of the way place, have officers trained to collect evidence properly. I have no doubt in my mind that the big city forensic team would be called in to assist for a 5 body piece together. In a large, metropolitan city, response time would likely be much faster. Especially if its 5 eviscerated corpses. More than likely within the hour if possible. In both cases, the first thing that is done is that the scene would be secured. Before I forget, no one can do anything to the scene until it has been released by the medical examiner (in Canada anyways. Not sure about other countries).
Once the big boys in the forensic unit arrive, the lead investigator/ officer in charge would decide the best way to fully document and examine the scene. Photographs and written notes are always always ALWAYS taken first, before anything within the confines of the scene are touched. It is generally easier to do this in indoor scenes than outdoor scenes. My bias for summoning monsters makes me think decrepit basement, but its up to you as a writer/ thinker of these kinds of scenarios where exactly the scene takes place. Keep in mind for outdoor scenes that weather is a bitch and will ruin every piece of evidence it can be it with rain, wind or snow.
After the documentation of the
scene is completed, evidence would be collected from most important to least
important. This is a sort of judgement call on the investigators part, but
usually goes from DNA (which is easily degraded or contaminated) to things
like footwear impressions and fingerprints (which will usually remain unless
by the rain).
After that the peeps back in the laboratory will try and get everyone’s bits back together as best they can to identify how many victims there are. Investigators will try and figure out how these people relate to one another, and how they came to be ripped to shreds.
The rest is up for you to decide. Does the monster rip any more people apart? Can the police identify this monster? Can they be swayed to believe in the existence of a supernatural creature, or is it up to the religious studies major to put the pieces together for the police (pun so intended). A lot of case work is following leads, and so it is up to you to figure out what the police will find, what that will tell them, and how quickly they can put the resources together to stop a literal monstrosity.
