The city medical examiner’s office Monday identified the 33-year-old moped driver who was killed Sunday in Makaha as David Tanimoto of Waianae. Police said Tanimoto was speeding on Farrington Highway when he struck a pedestrian near Moua Street at about 1:10 a.m. Tanimoto, who was not wearing a helmet, was thrown from the moped and taken to a hospital, where he died.

The pedestrian, a 32-year-old man, was taken in critical condition to a hospital where he is still being treated, police said.

It was the fourth traffic fatality on Oahu this year compared with 11 at this time last year.
