Why is Hilo, Hawaii so murdery, by murders?

Hilo is on the island of Hawaii, the big island, in Hawaii County. The show sets the scene the way an old sugar ledger would: plantations expanding through the late 1800s, workers arriving from Asia for the jobs, 26,000 Chinese labourers on Hawaii's cane fields by 1887, and the Hilo Sugar Mill producing 3,500 tons a year. A breakwater across Hilo Bay was begun around 1910 and finished in 1929.

Episode 419 carries two murders from one town, a generation apart: 24 December 1991 and 27 April 2015. Twenty-four years between them, both in Hilo itself, zero miles from the centre.

Hilo lands at 247 overall and second in Hawaii, modest for a town with this much history behind it. Sugar built the place, and the league counts what it counts.
