The professional hockey world is not a big one, in the scheme of the world. Lots of small-world connections, and that is no different for Sheldon Keefe.
A former junior hockey coach, named David Frost was accused of sexually assaulting many underage hockey players, including a man named Mike Danton. It took a wild turn after Frost had been acquitted of the charges laid against him when Danton was then arrested for the conspiracy of plotting to murder David Frost.
Relating back to Wes McCauley, one of the officials that officiated game 1, he and Frost are in fact, brothers-in-law.
