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.

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

He was taken to Harborview Medical Center where he was pronounced dead.
WSP asked the Seattle Police Department to take over the investigation.
