  • Details of Disappearance
    On September 17, 2004, Yvette and her friend, Brenda Cisneros, crossed the border from Laredo, Texas to Nuevo Laredo, Mexico to celebrate Brenda's birthday by going to a concert. Neither of them came back.

    Yvette's stepfather, William Slemaker, said a toll ticket showed the women crossed the border at 11:11 p.m. A relative saw them sometime after that at the concert. Slemaker also said that a friend spoke with the two women by cell phone around 4 a.m., about getting breakfast as they headed toward the international bridge back to Texas. On October 8, 2004, he found Yvette's 2001 white Mitsubishi Galant at a Nuevo Laredo tow yard. The stereo and battery were gone and the rear bumper had paint on it.

    There has been a rash of violent kidnappings and killings over the border in recent years, and family members fear that Cisneros and Martinez are victims of a crime.
