DNA testing has determined that skeletal remains found last year in an Uruguayan cemetery do not belong to the daughter-in-law of Argentine poet Juan Gelman.
A forensic examiner had recommended that the remains be examined. But Supreme Court spokesman Raul Oxandabart says tests done in Spain and Argentina came up negative.
Argentine officials say Maria Claudia Garcia was abducted in 1976 and sent to Uruguay, where she disappeared under the custody of dictatorship-era security forces.
Gelman family lawyer Jose Luis Gonzalez said Thursday that the news caused "anguish" and dashed hopes for a resolution.
Gelman is the 2007 winner of the Cervantes Prize, the most prestigious award for Spanish-language literature.
