Cannot speculate, but there must be something going on. We already have at least 3 different timelines as to when the shots started and where he was shooting.
Everybody is telling a different story about what happened, and now this? And since we know that whole area is monitored with video and audio, it should be the simplest thing in the world to just play the tape and see.
There is a cover up happening that is clear. Most likely the hotel and maybe the police are worried about legal liabilities.
