Peter Kosid was shot and killed on Sunday while crossbow hunting for deer on a friend's property on a Six Nations Reserve near Brantford, about 100 kilometres west of Toronto.
Six Nations Police said a deer hunter fired from the roadway into the bushline area. The bullet struck Kosid, who was wearing camouflage, from about 375 metres away.
Police said Jonathan and Kosid were not known to each other and were not hunting together.
Jonathan, a prominent member of the Six Nations band, was released after a bail hearing Wednesday. Details of the hearing cannot be revealed due to a publication ban.
His next court appearance is scheduled for Dec. 14.
Jonathan spent eight seasons with Boston and Pittsburgh and was known for his fighting skills as well as his scoring touch. His best offensive season was 1977-'78, when he had 27 goals and 25 assists in 68 games as the Don Cherry-led Bruins advanced to the Stanley Cup final before losing to Montreal in six games.
Jonathan finished his NHL career with 201 points (91 goals, 110 assists) and 751 penalty minutes in 411 games. He had 12 points (8-4) and 137 PIM in 63 career playoff games.
