The man behind a recent mass shooting in Las Vegas wrote a note beforehand about how to make the attack as deadly as possible, according to the police officer who found it.
Stephen Paddock’s note included hand-written calculations about where he needed to aim to maximize his accuracy and kill as many people as possible.
“I could see on it he had written the distance, the elevation he was on, the drop of what his bullet was gonna be for the crowd,” Officer David Newton of the Las Vegas Police Department’s K-9 unit told CBS News’s “60 Minutes” Sunday.
“So he had that written down and figured out so he would know where to shoot to hit his targets from there,” he added of Paddock’s 32nd floor hotel room at the Mandalay Bay Resort and Casino.
Newton was one of three police officers who stormed Paddock’s room while he fired upon a nearby outdoor concert.
The group ultimately found Paddock dead inside after he had committed the worst mass shooting in modern U.S. history.
Some Twitter users on Monday weighed in on the contents of Paddock’s note from the scene of the crime.

More than 20,000 people were at the Route 91 Harvest Music Festival when Paddock began firing upon it earlier this month.
Concert-goers were about 400 yards away from Paddock’s hotel room, well within the range of the custom-made rifles found in his suite.
The shooting killed at least 58 people and wounded at least 489 others, reigniting national debate over gun control.
