The Montreal Police Department has completed their investigation into Zdeno Charas hit on Max Pacioretty that broke Pacioretty's vertebra and gave him a season-ending concussion back in March.
With the police investigation over, its now up the Canadian authorities to decide whether or not theres enough evidence to charge Chara with a crime.
From Pro Hockey Talk:
Doing such a thing is extremely rare and in the case between these two with how the hit played out, theyd have to figure out if Chara had the intent to injure Pacioretty and that he acted in malice towards him to put his health at risk for the hit. Good luck figuring that out.
