SEATTLE, Wash. -

A man who attacked a turban-wearing Sikh cab driver faces years in federal prison when he is sentenced Tuesday in Seattle.

Prosecutors are asking for a four-year term for 50-year-old Jamie W. Larson of Federal Way, and his defense lawyer has asked for a two-and-a-half-year term.

Larson has apologized and said he was in an alcohol blackout in October 2012 when he beat the driver while shouting anti-Muslim slurs. The driver is an immigrant from India and not a Muslim.

Larson was originally charged with malicious harassment in King County Superior Court, but the case was turned over to federal prosecutors because the federal hate crime law carries a longer possible sentence of up to 10 years.

Larson pleaded guilty in June.
