Two South Islanders involved in a fatal shooting at their rural home on Thursday were Graeme John Dore, 67, and his special-needs daughter Sarah-Jane Dore, 27.

The pair were found at their Isla Bank house, 35km northwest of Invercargill. Police said no one else was sought in connection with the deaths.

Ms Dore competed at last year's Special Olympic World Summer Games in Shanghai.
