Vermont State Police say an autopsy has determined that a Ferrisburgh man who fell overboard into Lake Champlain died after being struck by the boat.
Forty-six-year-old Rene Viau did not resurface after falling off the small boat on July 23 when it went out of control near Kellogg and Porter bays.
Police say Viau was not wearing a life jacket. His body was found in the lake by searching family members on July 26.
