King County medical examiners have identified the man killed Sunday in a motorcycle wreck on state Route 18 in Covington.
Jacob Rinz, 22, of Kent was traveling west near the Green River Bridge when he crashed into a guardrail about 9:45 a.m.
Rinz was traveling about 90 mph when his motorcycle left the road and hit the left-side guardrail, according to the Washington State Patrol.
Rinz was thrown from his bike into the median, where he died.
The motorcycle slid across the highway to the right and came to rest on the shoulder of the bridge near the jersey barrier.
The crash blocked the left lane nearly three hours for the investigation.
