SCOTTSBLUFF, Neb. (AP) — A Nebraska judge has convicted a man of motor vehicular homicide in the death of a passenger.

Nineteen-year-old Bryan Bloom, of Henry, was accused in a June 2011 accident near the Wyoming-Nebraska state line that killed 18-year-old Johrdan Stone. He died after he stuck his head out of the window of a van Bloom was driving and was hit by a temporary road sign in a construction zone.

A judge found Bloom guilty on Tuesday following a bench trial last week. Sentencing is Sept. 14.

Bloom was also charged with manslaughter, but the judge dismissed that charge.

Prosecutors say Bloom was driving drunk and ran off the road in the construction zone. The defense says the sign was improperly placed in an unsafe location which caused Stone’s death.
