Kennewick police say it was an accident, a tragic one at that.

Wednesday evening around 6:45pm, emergency crews were dispatched to the 1400 block of West 20th. for a report of a pedestrian-vehicle collision.

Police and ambulance crews found the victim, a 4-year-old boy, had been accidentally run over by a vehicle driven by his father, Ismael Martinez Sr.  He'd been backing a car into the home's driveway, and didn't know the boy was behind him.

The boy was taken to TRIOS Southridge Emergency Room, suffering from what police said were "severe injuries."  Tragically, the boy died at the hospital from the trauma.

No drugs or alcohol were involved in the incident.
