The explosive compound found in the car and home of the Las Vegas mass shooter was similar to the one used last year by the Chelsea bomber.
Authorities recovered an undisclosed amount of the compound Tannerite from 64-year-old gunman Stephen Paddock’s home in Mesquite — and 50 pounds of the substance in his car parked at the Mandalay Bay Resort and Casino — where he gunned down concertgoers from the 32nd floor Sunday night.
Police have not yet explained why Paddock possessed the Tannerite — a compound created in 1996 for use in exploding targets that “produces a water vapor and a thunderous boom” when shot with a high-power rifle, according to the manufacturer’s website.
Investigators also found ammonium nitrate, which can be used to build bombs, in Paddock’s car.
The two bombs planted in Chelsea in September of 2016 — one of which exploded, injuring 31 people — contained Tannerite, police sources told The Post at the time. Those bombs also contained cell phone triggers and were packed with nails and ball bearings, the sources said.
Accused bomber Ahmad Rahimi is currently on trial in connection to the incident.
