The investigation isn’t over yet, so no there isn’t something like an “official timeline”. The best we’ve got, I think, is the police radio logs, since they are a record of what was going on as it happened, and they are publicly available.

The investigators gave information for the first day or two, but after the sadness of the situation became the news lead (the dead heroes, the funerals), the official investigators and the media have made a poor effort at informing the nation about further findings and making clarifications. Again, no one is on trial here; no legal need to keep investigations a secret.

I agree that they could do a better job, but I think you are making a mistake thinking that there is no need to keep the investigation confidential. People are speculating that there may have been other shooters. I don’t think that there were, but that is something the police are surely going to investigate, if only to rule it out.

Now, what if they DO find evidence of another shooter? If they had gone off half-cocked and released all the evidence to the media before discovering that, they would have tainted their investigation. So, it’s better to err on the side of caution, even if you think the perp is dead and there will be no trial.

Still, some things they surely could release, but haven’t, and that is disappointing.
