Scenario: There's been a murder - the head of a teenage male has been tossed into the middle of a Halloween party. The victim was one of the guests who wandered outside and in the space of minutes (there is supernatural involvement here, hence the speed) was decapitated and his head thrown in through a window, smashing it. His body is found outside, not too far away.
Question #1: What would be the police procedure for dealing with this many witnesses (30+)? All of them were in the room at the same time, and all say the same thing: the head just appeared.
Question #2: Two people did not witness the head's appearance - a young couple "otherwise occupied" out in the hallway. They heard the screams and came running into the main room. People confirm they came in from the wrong direction to be involved. The complication with these two is that the girl has recently become involved with the police - less than two weeks earlier she was mailed a human heart (taken from a murder victim) as a very nasty birthday "present". It's pretty obvious that the events are connected and that someone really doesn't like her. What do the police say/do about her?
Question #3: How long until the body is released to the family for burial? There's not much the body can say except what the weapon was and that it went through the obviously shattered window, if it helps.
