SEATTLE - A man is dead after officials say he jumped, while in handcuffs, off the State Route 520 bridge during a traffic stop.



According to Washington State Patrol, troopers pulled a driver over on the eastbound lanes of 520 on suspicion of DUI just before 2 a.m.



Troopers handcuffed the man and attempted to put him in the back of the patrol car.



That's when investigators say the 31-year-old Kirkland man jumped off the 520 bridge into Lake Washington.



Seattle Police's Harbor Unit searched for the man and found him after about 40 minutes.



He was taken to Harborview Medical Center where he was pronounced dead.



WSP asked the Seattle Police Department to take over the investigation.



Around 6:00 a.m., WSDOT shut down one lane of eastbound SR 520 for the investigation.
