PORT ALBERNI, British Columbia — Residents of Port Alberni on Vancouver Island tout their small town as the salmon capital of the world and also like to boast that it produced Canada’s only female prime minister.

These days, though, Port Alberni has become known for something more sinister: as the birthplace of the Canadian teenagers believed to have gone on a bloody rampage last month, accused of killing a botanist and suspected in the murder of two other people.

A cross-province manhunt for them lasted nearly three weeks before their own bodies were discovered last week in the remote northern Manitoba bush, after they had traveled nearly 2,000 miles. The Canadian police confirmed the identity of the bodies on Monday after an autopsy and said the suspects had died of self-inflicted gunshot wounds.
