The mystery has been solved. After weeks of the New Jersey Devils and Los Angeles Kings searching for the puck that was on the ice when the Kings won the 2012 Stanley Cup, the Devils' Patrik Elias says he found the highly-coveted puck on June 28 in his equipment bag after returning from a vacation, according to Rich Chere of the Star-Ledger:
"As I told you, I had no idea what had happened to it, so I went to check in the locker room and it was there," Elias told me. "So I returned to to the rightful owners."
Elias was seen in game footage throwing the puck in his glove and then handing his stick to someone in the crowd after the Kings won the Stanley Cup in Game 6. At the time, it wasn't clear whether Elias had also handed the puck to someone in the crowd.
