It's presumably being treated as a crime scene: hence for continuity purposes they need to know who's been in the scene and when - for things such as elimination of footprints etc if that becomes relevant, if anything is moved, added or taken away from the scene. In an ideal world you would preserve a scene precisely as it was at the time of the incident (adding nothing and taking nothing - including people) so that it can be forensicated, photographed etc.
The scene may remain open pending investigators having spoken to all paries involved and so on....because sometimes the significance of various things within a scene only become significant after the story starts to be pieced together.
Hence crime scenes can be open for very long periods of time....as inconvenient as that may be....or would some people rather these things aren't investigated properly?
