A note containing handwritten numbers for wind, trajectory, and
distance was discovered by Stephen Paddock’s body inside the

“I could see on it he had written the distance, the elevation
he was on, the drop of what his bullet was going to be for the
crowd,” Newton said in a clip from the the episode, which will
be televised on Sunday night. “So he had had that written down,
and figured out so he would know where to shoot to hit his
targets from there.”
Pressed about what the meaning of the numbers were, Newton
said, Paddock “must have done the calculations online or

In addition to killing 58 people in his attack, Paddock injured
at least 489 others before taking his own life.
Paddock was known for playing gambling games in casinos for
hours at a time, with little or no human contact.
Profilers and behavioral scientists this week were brought in
to examine witness interviews and investigative summaries to
better understand what drove the Mesquite, Nevada, man to
execute and injure so many in such a calculated and detached
They are particularly focused on the period of September to
October 2016, when Paddock began buying 30-plus guns, in
