(CBS Boston) -- When Tom Brady unveiled his recovered Super Bowl jersey during opening day ceremonies at Fenway Park Monday, no one was happier than 19-year-old Dylan Wagner.

He is a sports memorabilia collector and avid Patriots fan who helped federal investigators recover both of Brady’s missing jerseys.

Wagner says it all started shortly after this year’s Super Bowl when news surfaced that Brady’s jersey from the Super Bowl victory against Seattle in 2015 had also been swiped.

“I knew exactly who had it,” Wagner said.

Wagner told the I-Team that he not only knew who had the Super Bowl 49 jersey; he also told the FBI where they could find it.

“I was able to provide two addresses to search,” he said.

Last December after selling Martin Mauricio Ortega a jersey on eBay, the two exchanged photos of their collections.

“He sent me 30 photos of his collection. Front and center was Tom Brady’s Super Bowl 49 Jersey. I asked him outright, ‘How did you get that?’ and he says ‘I’ll tell you later,’” Wagner explained.

At that time, there were no reports that the Super Bowl 49 jersey was stolen property. So Dylan shared Ortega’s photos with his friend, Boston ATF Special Agent Christopher Arone, who is also a collector.
