“Please! Please! Please! Be aware of motorcyclists on the road! It is with deep sorrow that I have to say that 65 year Des Moines man who lost his life yesterday morning was my beloved brother Jefferson Peter! He will be missed terribly, to say the least. He is now in God’s loving hands and is now with is loving wife, Karla, their dog Winston and our parents. I miss you Jeffie!”
A fatal motorcycle crash Wednesday morning temporarily closed northbound Pacific Highway at South 240th Street near Highline College.
The collision occurred just before 7 a.m. Aug. 23 when the driver of a vehicle struck a motorcyclist while changing lanes, according to Cmdr. Jarod Kasner of the Kent Police Department.
Bystanders were conducting CPR on the motorcyclist in the road when rescue workers arrived, according to South King Fire & Rescue Battalion Chief Ryan Herrera. The motorcyclist — identified as a 65-year-old Des Moines man — was pronounced dead at the scene.
No other injuries were reported.
A 61-year-old Auburn man was arrested and faces a vehicular homicide charge, Kasner said. The Kent Police Department is investigating the incident and has applied for a warrant to test the driver’s blood. Lanes were closed for about two hours and drivers redirected.
