Timothy Lee Herbert, a pizza delivery driver from Maple Valley, is accused of striking and killing Alex Hubbard after the youngster walked out of his house in his pajamas last Wednesday night.

The King County sheriff's office says one driver saw the boy in the road, stopped and was trying to alert an oncoming car when it struck the boy. The car then left the scene.

The sheriff's office says Herbert was arrested the next day after the office received information from his co-workers that an upset Herbert had told them he hit something with his car.

The sheriff's office says Herbert also told co-workers and a deputy that he had been drinking before the accident.

Herbert's arraignment is scheduled for June 29th. If convicted, he would face a standard sentencing range of 31 to 41 months in prison.
