Ventura man sentenced to over 7 years for fatal crash of high school graduate

The Ventura County District Attorney's Office announced the sentencing Friday of a 27-year-old Ventura man convicted of killing a recent high school graduate during a DUI crash last June.

Mario Adan Arjon, 27, of Ventura, was sentenced to seven years and eight months in state prison for one count of gross vehicular manslaughter while intoxicated, driving with a blood alcohol content of 0.15 percent or higher and causing injury to multiple victims while driving under the influence of alcohol.

On June 15, Arjon was driving in the early morning at a high rate of speed in the area of Rio Mesa High School in El Rio.  While driving along Central Avenue, Arjon rear-ended a car that had slowed to a stop at the intersection with Vineyard Avenue. 

The car was being driven by Fernando Buenrostro, 18, of Oxnard, a graduating senior from Rio Mesa High School who had just returned from graduation night at Disneyland. The impact from the collision caused Buenrostro's car to hit a third car stopped in front of it and rotate into the intersection, authorities said.

Buenrostro, two passengers in his vehicle and the driver of the third vehicle were all injured from the crash. Buenrostro was transported to Ventura County Medical Center for treatment but succumbed to his injuries three days later.

An investigation into the crash by the California Highway Patrol later revealed that Arjon's blood alcohol content was 0.15 percent at the scene of the incident, nearly double the legal limit of 0.08 percent.
