Update: Material Witness Sought in Deadly Crash (Photo) - 03/19/19

Investigators with the Washington County Crash Analysis Reconstruction Team (CART) are seeking information on a material witness who was seen driving through the incident scene. Investigators are releasing images and two short videos of the vehicle in question.

The vehicle appears to be a white Kia Soul.

Anyone with information on the driver of the vehicle or information related to the crash is asked to contact Officer Dalton with Beaverton Police Department at (503) 526-2260.

Investigators were initially looking for another white vehicle associated with the crash. Investigators were able to identify the vehicle, and it’s driver shortly after the initial crash.

The original media release is below.


On Saturday, March 9, 2019, at 6:59 p.m., Washington County Sheriff’s Office deputies responded to reports of a person who had been hit by a car while crossing SW Tualatin Valley Highway, just outside the City of Cornelius.

Deputies arrived to find the body of a 59-year-old man from Hillsboro, who appeared to have been hit by a white 2006 Honda Accord with front-end damage. The driver of the car, a 20-year-old man from Cornelius, remained on the scene and is cooperating with investigators.

The initial investigation indicates the driver of the Honda Accord was driving westbound on SW Tualatin Valley Highway at NW 334th Avenue when the crash happened.

A witness reports a possible second vehicle may have also hit the victim, but that vehicle or driver have yet to be identified.

The possibility of driver impairment is also under investigation.

The victim of the crash has been identified as Dionicio Olvera of Hillsboro.

The highway was closed for several hours following the crash while the Crash Analysis Reconstruction Team (CART) began its investigation.

CART is a multi-agency team of specially trained law enforcement officers from the sheriff’s office and the Beaverton, Cornelius, Forest Grove, Hillsboro, King City, Tigard, and Tualatin police departments. The Washington County District Attorney’s Office also has an assigned deputy district attorney on the team, who responded to this crash.

The sheriff’s office would like to thank the Oregon Department of Transportation (ODOT) for setting up a detour while the investigation was underway.
