Why a 46-year-old Renton man died while running in the Highlands April 18 was still pending mid-week.

The King County Medical Examiner’s Office identified him as Satoru Ozeki, who worked at Microsoft as a senior account manager for 12 years.

Ozeki collapsed and died on Northeast 10th Place while on a run. Attempts were made by emergency personnel to resuscitate him.

Ozeki, who was known as Sonny, enjoyed golfing, fishing, mountaineering, mushrooming, traveling, kayaking, backpacking and the outdoors.

His memorial service will be held at 9 a.m. Thursday at Greenwood Funeral Home, 350 Monroe Ave. N.E.
