ROSEBURG, Ore. -- A Douglas County grand jury indicted a Roseburg teenager accused of driving drunk in a single-vehicle crash that killed two teens and injured another.

The Roseburg Police Department says Jacob Gonzales has been charged with manslaughter, assault and driving under the influence of intoxicants.

The 16-year-old is being prosecuted as an adult and was lodged Wednesday at the Douglas County Jail.

Gonzales was behind the wheel of a car that struck a power pole and a fir tree March 28. He was 15 at the time and did not have a driver's license.

The authorities say Gonzales had a blood alcohol content of nearly twice the legal limit for a licensed driver old enough to drink.
