Thordur Bogason said Thursday that his client, 9-year-old Jinky Young, gave blood samples in December to determine if she is Fischer's daughter. Jinky lives in the Philippines with her mother, Marilyn Young. He says asking the Supreme Court for permission to exhume Fischer's body really was a last resort.
The American-born chess grandmaster died in January 2008 in Iceland, where he had been living since 2005, after renouncing his U.S. citizenship.
Bogason says Fischer had died without a will, and there are other legal actions ongoing to determine who is entitled to his estate.
