Maria Elizalde would be 18 years old and now billboards across North Texas will flash her picture more than 50 times an hour in hopes someone knows where she is or who is responsible for her disappearance.

The Texas Center for the Missing is partnering with Clear Channel Outdoor Americas for the month-long digital billboard effort. Maria went missing in Dallas on November 25, 2015 and could possibly still be in the Dallas, Cedar Hill or Balch Springs area.

Maria’s mother, Kathleen Rodriguez, says she is desperate to have her daughter home. “It’s been almost three years. I haven’t seen her. I haven’t heard from her. Nobody seems to know where she is. So, if anybody out there knows anything please come forward.”

Last year the Texas Department of Public Safety Missing Persons Clearinghouse received more than 41,000 reports about missing juveniles. The billboards featuring Maria are in recognition of National Missing Children’s Day.

Maria is biracial, of Hispanic and American Indian descent, stands five feet tall and at the time of her disappearance weighed approximately 140 pounds and had the ends of her hair died blue.

The billboards across North Texas will have an age progression photo of what Maria could look like today. The picture will be featured 1,200 times a day for one month.
