A 20-year-old driver from Medina who was allegedly speeding and talking on his cell phone caused an accident on eastbound I-90 on Aug. 8 that killed one person and injured another.

According to a Washington State Patrol press memo, at 2:10 p.m. a male driver from Medina was traveling eastbound on I-90 near State Route 18 in the left lane and drifted onto the left shoulder and struck another vehicle, which was driven by a 29-year-old Redmond female. Her deceased passenger, Sohel Ahuja, was identified by the King County Medical Examiner’s office on Monday.

The Medina man — who witnesses said was driving with his ‘phone to his ear’ and over the 70 mph speed limit — was arrested for vehicular homicide and vehicular assault for driving with disregard for the safety of others, trooper Chris Webb said in a press release.

When officers arrived, the female driver was standing outside of her 2008 Honda Civic near mile post 26. She was critically injured and transported to Harborview Medical Center. The driver of the 2002 Toyota Highlander was uninjured.

The roadway was partially blocked for approximately two and half hours.

At press time, the cause of the accident and charges are under investigation. The Washington State Patrol is asking witnesses to call or contact detective Russ Haake at russ.haake@wsp.wa.gov or (425) 401-7717.
