The 60-year-old man who died Monday in a one-vehicle crash on Kunia Road has been identified by the Medical Examiner’s Office as Steven Lewis of Waipahu.

Police said Lewis may have suffered a medical condition before the 9:45 a.m. crash, but medical examiners have neither made that determination nor found a cause of death yet.

Police said Lewis was driving a red Ford Ranger heading north on Kunia Road when it crossed the centerline, then veered back and went off the roadway into a fence and overturned.
