Kennewick police and Benton County Coroner John Hansens have identified the pedestrian killed Wednesday on Clearwater Avenue near WinCo.

David Paul Ratliff, 60, of Kennewick, had just gotten off a Ben Franklin Transit bus and was walking through a parking lot when an out-of-control truck hit him, officials said.

Ratliff had lived in the Tri-Cities for 36 years and was a retired nuclear process operator at Hanford.

The name of the truck driver, an 84-year-old man from Pasco, has not been released. Police said he is cooperating with the investigation.

The driver told officers the accelerator stuck, causing his truck to careen out of control. He slammed into a parked car before hitting Ratliff and then continued over landscaping rocks, out of the parking lot and down Clearwater Avenue before his axle broke.

It was the first of two wrecks Wednesday morning that tied up traffic in both directions on Clearwater Avenue. The second happened about 15 minutes later and three blocks away when a bicyclist was hit and dragged under a truck.

Cayiah Ramble, 32, of Kennewick, pulled out of a parking lot at the V&H Market and turned right to go east on Clearwater Avenue when she hit Deborah Fox, 54, of Kennewick.

Ramble reportedly was looking left and didn't see Fox, who was on her right, officials said.

Fox and the bicycle were dragged under Ramble's Ford F-150 truck for about 270 feet. Ramble also apparently didn't realize she had hit Fox, and told authorities she thought something was wrong with her truck.

Fox was flown to Harborview Medical Center in Seattle and remained in critical condition Thursday night.
