The ultimate question, was Paddock a loner or not?
...
In a press conference on Wednesday, Clark County Sheriff Lombardo was asked if he saw evidence that Paddock had planned to escape after the attack.
The sheriff said "yes". Asked what it was, he said: "I can't tell you."
Sheriff Lombardo was asked by a reporter if he thought Paddock had carried out the attack alone.
"You've got to make the assumption he had to have some help at some point," the sheriff replied.
"Maybe he's a super guy, maybe he was working out all this on his own, but it would be hard for me to believe that."
The possibility that Paddock could have had an accomplice is a twist in the investigation.
