A high-ranking Ecuadorean official says his government is talking with Mexico about establishing a bank of DNA material from some of the migrants from his country who have disappeared trying to reach the United States illegally.

Humberto Cordero, undersecretary for the Community of Returned Ecuadorean Migrants, told The Associated Press on Wednesday that the genetic material could help determine if Ecuadoreans are among unidentified remains found in Mexico.

Cordero says Ecuadorean police have sent some DNA to Mexican authorities in the past in the hopes of identifying the remains of migrants.

Mexican authorities did not immediately respond to a call seeking comment.

Last year, Ecuador registered 128 cases of migrants who disappeared trying to reach the U.S.
