Benton County Coroner John Hansens says Kevin Lopez-Gonzalez died at the scene. He was sitting in the front passenger seat and was wearing a seat belt.
Hansen says Carlos Ochoa died two hours later at Kadlec Regional Medical Center. Ochoa was thrown from the car. Hansens says it's not clear whether Ochoa was wearing a seat belt at this time.
The crash happened on Evans Road about three miles north of Grandview around 6 p.m. Tuesday. Deputies say the car was speeding when the driver lost control on a curve, went off the road and wound up in some trees.
The executive director of human resources for the Grandview School District confirmed the driver is 17-year-old Jovannie Razo. He is in the Intensive Care Unit at Kadlec Regional Medical Center in Richland. Benton County deputies say Razo is on life support.
Deputies say all three in the car went to Grandview High School. Additional grief counselors have been brought to the school today to work with the students.
Deputies say there is no evidence of drugs or alcohol. Speeding was a factor but they can't rule out a mechanical problem.
BENTON COUNTY, Wash. -- Benton County sheriff's officers say two teenage boys were killed and another seriously injured in a one-car crash Tuesday evening about three miles north of Grandview.
Deputies say sometime after 6 p.m., the boys were speeding on Evans Road, north of Grandview when the driver lost control on a curve. The car rolled several times before coming to a rest in a clump of trees.
One boy was killed at the scene, another died at the hospital. The third was flown to a hospital.
Deputies said all three are Grandview High School students. Their names have not been released.
"We did have some witnesses to the accident so we were able to gather some information from the witnesses about what happened and therefore that's why we had decided that speed was one of the factors in this accident," said Kevin McCary, Benton County Patrol Sergeant.
