The Wild GM has apparently been under investigation for the past couple of weeks after a team employee accused him of verbal abuse in the workplace. The matter appears to be have been taken seriously by the team as Guerin was not present at the board of governor's meetings due to the ongoing investigation. Michael Russo of the Athletic has the full story.
While the team is certainly being very careful about what information they reveal about this specific case, they have made it clear that they intend to keep Guerin in his role as the team's GM. The team and the NHL were both apparently satisfied with the investigation in that it did not reveal that Guerin had committed a fireable offense.
Other than that, there has been very little information revealed about the case other than the individual that made the allegations. Reportedly, it was Andrew Heydt, the team's director of operations and player relations. It remains unclear what his future with the team is at this moment.
