A man temporarily extradited from the U.S. has told a court he and two other men killed at least 10 women in the Mexican border city of Ciudad Juarez.

Jose Granados, 30, acknowledged to a judge on Wednesday that they killed the women from about 1993 to 2006. He testified that one was buried in his back yard.

Granados said Edgar Alvarez, who was sentenced to 36 years in prison in one of the killings, masterminded the kidnappings and killings.

Chihuahua state prosecutor's spokesman Alejandro Pariente said Granados will be sent back to the U.S. to finish serving a three-year term for immigration violations while his trial continues in Mexico.

Ciudad Juarez is across from El Paso, Texas.
