SAN ANTONIO – Tx — Pauline Diaz disappeared without a trace nearly 16 years ago. Today, on what would have been her 80th birthday her family gathered in front of her home to sing her happy birthday and to plead with whoever took her to let her come home.

Pauline vanished from the H-E-B on Southeast Military Dr. on Dec. 7, 2010. H-E-B surveillance video showed Pauline leaving the store and walking to her truck. She stopped to speak with an unidentified woman and then was never seen again.

“Mom, I want you to wish you a happy birthday,” Juanita Diaz said. I’ll never stop looking for you. You’re always in my heart everywhere I go.”

Pauline’s daughter Juanita Diaz says the past 15 years without her mother have been rough, and the pain of not knowing what happened to her mother has grown stronger over the years.

“I feel that my mother has passed,” Diaz said. “My word to the public is I know that someone out there knows where’s she’s at. All we want to know is where she is.”

Crimestoppers is offering $25,000 reward for information leading to Pauline’s location.

Anyone with information is asked to contact the Bexar County Sheriff’s Office.
