Never mind my post! I found it, CBS reporting he may have tried for previous attack.
There was a posting here on FR this afternoon that mentioned a report that the shooter tried to rent a room on September 22nd at The Ogden Hotel and/or another hotel in downtown Las Vegas, with a vintage point for a “Life is Beautiful” concert.
The hotels were booked solid so he abandoned his plans.
Don’t know if this is true, but this is what was reported earlier today.
