The investigators are puzzled by two discoveries: First, a charger was found that does not match any of the cell phones that belonged to Stephen Paddock, the man who killed himself inside the Mandalay Bay Resort and Casino after sending a barrage of bullets down on a crowd of 22,000 people below.

And second: garage records show that during a period when Paddock’s car left the hotel garage, one of his key cards was used to get into his room.
