The omnibus hearing for an off-duty Washington State Patrol trooper accused in a Richland crash that killed a 20-year-old motorcyclist has been pushed back to Aug. 12, 2026. The trooper, Sarah Lee Clasen, is charged with vehicular homicide in the March 1, 2025 collision that killed Jhoser Emmanuel Vega-Sanchez. Defense attorneys say they need additional time to sift through evidence from several agencies.
According to Elkhorn Media Group, the Spokane County Prosecutor’s Office requested the continuance to allow for more discovery and file review. Defense attorney Scott Johnson told the outlet his team is still working through a large stack of reports, body-worn camera footage and lab results. Elkhorn also reports a pre-trial status hearing set for Sept. 10 and a jury trial penciled in for Sept. 28, 2026.
Crash details and civil suit
Investigators say Clasen turned left from State Route 240 into the Horn Rapids neighborhood and struck Vega-Sanchez’s motorcycle. He later died at a Tri-Cities hospital, according to The Spokesman-Review. The victim’s family has filed a wrongful-death lawsuit in Benton County Superior Court, with attorneys from Tamaki Law handling the civil claim. Local residents have been leaving flowers and signs near the stretch of highway where the crash happened as the legal process grinds forward.
Toxicology and investigation
A blood-alcohol test taken hours after the collision measured Clasen’s BAC at 0.17, more than twice Washington’s legal limit, according to a probable-cause affidavit reviewed by Law&Crime. Richland police say Clasen initially refused field sobriety and preliminary breath tests at the scene, and officers later obtained a warrant for a blood draw. Prosecutors have indicated they will need to show that impairment was a proximate cause of the collision to secure a criminal conviction.
State Patrol response
The Washington State Patrol placed Clasen on paid administrative leave and said the Richland Police Department is serving as the primary investigating agency, according to an agency press release (WSP). As reported by Elkhorn Media Group, WSP Director of Public Affairs Chris Loftis said the agency will wait for the criminal case to run its course before deciding on any internal personnel action.
Legal stakes
Clasen is charged with vehicular homicide, an offense codified in RCW 46.61.520 and treated as a felony under Washington law; see the statute as published by Justia for the full language. The statute links vehicular homicide to the state criminal code’s felony sentencing framework. The criminal prosecution is moving on a separate track from the family’s wrongful-death civil action, and each case carries its own burden of proof and timeline.
Family and community reaction
The victim’s family has said they are pursuing accountability and civil damages, according to a press release from Tamaki Law. Friends and neighbors have held vigils and placed memorials near the crash site while the court proceedings play out. Court filings and local coverage indicate the case has drawn sustained public attention in the Tri-Cities region.
What to watch next
The next scheduled court appearance is the Aug. 12 omnibus hearing. In the months leading up to that date, both sides are expected to continue exchanging discovery, and pre-trial motions are likely. If prosecutors keep the September dates on the calendar, the case could move toward a Sept. 10 pre-trial hearing and a late-September jury trial, although defense requests and disputes over evidence could shift the schedule again. This story will be updated as new filings or official statements become public.
