You have a very good question.
I’m finding more info from other articles on this sheriff talk. I was thinking of posting other articles but will try to wait until i can find whole unedited transcript/video instead.
I was surprised to hear a gun dealer who sold the guns to him claiming that his girlfriend was in the store with him, that sounds like major new info
“Police also told a news conference that 317 of the 489 people injured in the Las Vegas shooting have been discharged from hospitals.”
Non fatal, non permanent injuries. Good news compared to initial assumed reports. So really 180 abouts seriously wounded.
Rumors in the gun industry are that she was often with him at gun stores. I suspect that gun store video will emerge soon.
