SAN ANTONIO – The family of Pauline Diaz, the San Antonio grandmother who has been missing for over a decade, will be gathering to celebrate her 79th birthday.

Pauline Diaz’s daughters said they have felt nothing but agony and heartache for the last 15 years since their grandmother went missing in December of 2010.

Diaz was last seen leaving her job at HEB on Southeast Military Drive and Goliad Road.

Since then, her family including her daughters, Juanita and Paula, returned to that same corner hoping to raise awareness.
