So What's on That Note Left by Vegas Shooter?

Las Vegas gunman Stephen Paddock did indeed leave a note of sorts in his hotel room, but authorities say it wasn't a suicide note or anything that provides an obvious clue about a motive for his shooting spree. Police won't reveal details about its contents, with Sheriff Joseph Lombardo saying only that the piece of paper contained numbers now being analyzed to see if they might shed some light, reports the New York Times. Speculation about the note has been percolating since one of the leaked photos from Paddock's hotel room revealed its existence. (Business Insider zeroes in on that detail here.)

Barring some kind of unexpected clue from the note, investigators aren't sure when they'll be able to piece together a motive as they pore over details of Paddock's personal and financial history. "I've been doing this a long time and I can’t remember another homicide—and then you multiply what I'm about to say by 58—where you don't know why," says Stephen Wolfson, the district attorney where the killings took place. Police, meanwhile, say an explosive compound discovered in Paddock's car and home was Tannerite, the same one believed to have been used in a 2016 bombing in New York City, reports the Las Vegas Review-Journal. Paddock had more than 50 pounds of it (The night before the massacre, Paddock called hotel security to report a noisy neighbor.)
