(Portland, OR) -- The conviction of the driver who struck and killed two Forest Grove girls in a leaf pile is being overturned. The children were playing in a leaf pile in the street in October of 2013 when they were hit by Cinthya Garcia-Cisneros, who told police she didn't stop because she hadn't realized she had hit anything. Yesterday, the Oregon Court of Appeals ruled that Garcia-Cisneros had no reason to know the girls were in the leaf pile. The court also ruled that she had no reason to return to the scene. Washington County prosecutor Bracken McKey says the case can't be re-prosecuted because the court ruled the driver's "conduct was not criminal."
