SAN JOSE, Calif.A Stanford law school graduate is facing tax evasion charges over thousands of dollars she was allegedly paid while working as a prostitute.

In court papers filed in San Jose federal court Tuesday, prosecutors allege that Cristina Warthen failed to pay taxes on more than $133,000 they say she earned as a prostitute in 2003.

Warthen -- then Cristina Schultz -- first came to the attention of the federal government several years ago when authorities seized more than $61,000 in cash from her home

Since then, the 34-year-old Schultz has married David Warthen, the co-founder of the online search engine Ask Jeeves, now known as Ask.com.

A lawyer for Christina Warthen declined to comment on the charges.

Warthen is scheduled to appear in court Oct. 16.
