The burglary of Pittsburgh Penguins star Evgeni Malkin's home, in which his three Stanley Cup championship rings were apparently stolen, has become a mystery.

The location of the rings is not, at least anymore. The three rings — from championships won in 2009, 2016 and 2017 — were found elsewhere in Malkin's home Wednesday, four days after the reported burglary, according to Allegheny County Police.

Malkin's home was broken into Saturday while the Penguins were playing a home game versus the Ottawa Senators at 4 p.m. He did not play in that game after going on injured reserve with an upper-body injury earlier last week.

The back door to the house was reportedly kicked in and a safe left open. The home's alarm system did not trigger and the cameras were down. No one was in the residence at the time of the break-in.

The 19-year NHL veteran confirmed to The Athletic that his home's security system had been dismantled, in addition to a safe being left open and the rings being missing. Whether or not anything else was stolen from the home has not been reported.

Despite the rings being located, the burglary is still an active investigation, Allegheny County Police announced.

The FBI is also involved in the investigation, which should not be a surprise considering the trend of high-profile athletes whose homes have been broken into, including Patrick Mahomes, Travis Kelce, Bobby Portis, Joe Burrow and Luka Dončić.

The NFL and NBA issued security alerts to teams and players warning them to bolster their security systems, employ protective personnel and be cautious about showing homes and announcing whereabouts on social media.

League memos warned that theft rings, possibly organized international crime rings, were "primarily focused on cash and items that can be resold on the black market, such as jewelry, watches and luxury bags."

NHL deputy commissioner Bill Daly told The Athletic that the league "has been in touch with clubs" about the recent burglaries of professional athletes.
