Carlos Siordio, the man who killed a 9-year-old boy outside Mollie Stone’s grocery store in San Mateo in 2008 will go to trial Oct. 13. Siordia, who is charged with misdemeanor vehicular manslaughter, faces up to one year in prison for the death of Tyler Fahy and for seriously injuring his mother.

The 43-year-old was driving a construction truck that plowed through an intersection and struck the SUV carrying the pair. Siordia pleaded not guilty.
