The King County Sheriff's Office says the woman was walking her dog near the intersection of 185th Street and 62nd Avenue NE in Kenmore at about 1:30 a.m. when she spotted a man lying motionless in the front lawn of a home.
Medics and deputies responded to the scene, but the man had suffered too much trauma to perform CPR. He was pronounced dead at the scene.
Family members identified the victim as 31-year-old J.D. Humphreys of Kenmore.
"He was a very good kid," said his father Mark Humphreys. "He's well-loved and well liked by all that knew him... he was not mean-spirited."
Mark Humphreys says his son was walking to his home about four blocks away when the crash happened. Investigators say detectives concluded Humphreys had been hit by a vehicle then left to die by the side of the road.
"Mostly he was hit and killed and left. And that's no good," Mark Humphreys said. "I don't really know what that person did. I'm assuming they drove off. I don't know if they got out to look. I wish I knew that."
Debris left at the scene included part of a headlight that likely came from a 2003 or 2004 Ford F150 pickup, said Sgt. Cindi West of the King County Sheriff's Office. Detectives said the damaged headlight came from the front passenger side of the vehicle.
"I can't imagine that this person didn't know that they hit something," West said. "Whatever reason they fled, I don't know. Maybe they were intoxicated at the time. But at this point it doesn't matter -- they need to come forward. This man has family."
On Monday afternoon, detectives announced they had found the truck thought to have been involved in the hit and run. Not longer after the truck was recovered, West said a 24-year-old Kenmore woman turned herself in to police.
A family who wants answers.
"I'm real angry about what makes a person have to think that way," Mark Humphreys said. "I think that the person was scared and left because they were scared... is he afraid he's going to go to prison for a long time? I don't know any of these answers. I really don't know what happened. J.D. is a real good kid."
