A medical condition caused the death of a 60-year-old Moanalua Valley man involved in an early morning crash on Friday, according to the Honolulu medical examiner's office.

The ME's office today identified the driver as Ted Teramoto. Autopsy findings listed cause of death as cardiac arrhythmia and manner as natural.

Teramoto was driving a 2000 Honda CRV on Ala Aolani when the vehicle veered off the roadway and collided with a driveway tile wall at 2:58 a.m.

The case was investigated by police as an unattended death, not a traffic fatality.
