Andrew Dinsmore is in the hospital unable to walk because he was hit by a car while riding his bike in Kent Friday.
Police are looking for the driver.
Dinsmore is in serious condition with broken bones and cuts.
His father, Don Dinsmore, has made several visits to the intersection of SE 256th Street and 135th Avenue SE looking for clues.
"It's devastating. Of course, they didn't tell me how much damage it was," said Dinsmore. "He's 47 years old, but he's my kid, you know."
Don Dinsmore said his son has a disability, and he's often spotted riding his special three-wheeled bike to and from work. He is part of the nutrition services team at the Kent School District.
Andrew Dinsmore was taking his usual route to work when he was hit.
"It was 5:30 in the morning, and he got in the bike lane," said Dinsmore. "You've got to remember this kid has got lights. He looks like a Christmas tree coming down the road. He got hit there. He said that a car had no lights on coming down."
Don Dinsmore said the driver that hit Andrew kept going. His son told him it was a light-colored vehicle.
"They said 10 months to a year before he can do much of anything," said Don Dinsmore.
"I mean it could have been an accident, a total accident, but to back up and take off after they hit him, that is what gets me," said Don Dinsmore.
Andrew Dinsmore's family is passing out flyers with the hope that witnesses or people with information will come forward. Anyone with information is asked to call Kent police at (253) 852-2121.
