A 50-year-old driver accused of injuring a man and his son, resulting in the younger man losing part of his leg, in a crash on Beacon Hill Saturday night was charged today with two counts of vehicular assault.

Rodney James allegedly had a breath alcohol content of 0.16, twice the legal limit, according to charging papers filed in King County Superior Court. Police say that James was speeding east in the 1700 block of South Columbian Way when he lost control of his 1998 Corvette. The sports car slid across a sidewalk, into a driveway and into Wah Wong and his son who were standing, court papers said.

Injured were Wah Wong, 67, and Jason Wong, 22. Salina Wong, Wah Wong's 60-year-old wife, was injured after James' car struck a car she was sitting in, charging papers said.

Police found unopened beer cans in James' car and smelled alcohol on his breath, court papers said.

King County Senior Deputy Prosecutor Amy Freedheim said in charging documents that James was convicted of reckless driving in January -- a charge that had been reduced from driving under the influence.
