A Bothell man riding a motorcycle was killed Friday after a Jeep plowed into three motorcycles near mile post 33 on State Route 410.

Thomas J. Finken, 60, was riding his Harley Davidson FLTRI east on SR 410 shortly before noon on July 15 when a westbound 2014 Jeep Cherokee, driven by a 73-year-old man, crossed the median and hit Finken and two other vehicles, according to a Washington State Patrol report.

Finken died at the scene and the driver of Jeep and another driver were taken to Harborview Medical Center. The fourth driver was not injured. Other than the Cherokee, all three of the other drivers were on motorcycles.

The accident closed eastbound SR 410 for six hours.

Troopers are investigating the cause of the accident and did not know if intoxicants were involved.

No charges have been issued yet, pending results from the investigation.
