A man was killed early Monday morning after falling out of a moving vehicle on southbound I-405 in Kirkland.

The man fell from out of the vehicle's sunroof while possibly "car-surfing," according to WSP Trooper Rick Johnson.

The vehicle, a blue BMW, continued on I-405 and was found abandoned in the city of Kirkland. A K9 track is in search of the driver.

All southbound lanes of I-405 reopened after a two-hour closure.
