SAN FRANCISCO (AP) – A northern California woman has been indicted on federal charges accusing her of illegally importing guitar picks made from endangered turtle shells.

An indictment unsealed Friday says 54-year-old Qing Song of Santa Rosa imported picks or raw shells of the Hawksbill sea turtle from China and sold them in California. It’s illegal to trade endangered wildlife without a permit for scientific research or other approved, noncommercial use.

Some musicians prefer shell picks over plastic picks because they believe the shells produce a superior tone.

Song is charged with two misdemeanors and a felony count of trading in endangered species. She also is accused of selling 74 picks and possessing another 899.

Records did not indicate she has a lawyer.
