Luis Antonio Alderete-Martinez was three years old when he disappeared on June 1, 2015, in El Paso, Texas. That morning his father, Luis Aragon-Alderete, dropped him at preschool; the plan was for non-custodial mother Regina Martinez to pick him up for a short vacation. Both adults vanished after that pick-up did not occur and the father’s repeated attempts to reach Regina failed. When the father went to the daycare, staff said Luis was not there.

Authorities believe his mother abducted him and a felony kidnapping warrant for Regina Martinez was issued February 18, 2016. Regina Martinez, also known as Regina Martinez Dorantes, was born May 10, 1988, and is described with black hair and brown eyes; Luis was born March 22, 2012, has black hair and brown eyes, and spoke English and Spanish. Investigators suspected she may have taken him to Mexico.

If anyone saw Luis or knows where Regina Martinez might have taken him after June 1, 2015, please contact the El Paso Police Department.
