SAN ANTONIO -

Linda Mares' life has been on hold since she learned her daughter 34-year-old Betty Jane Zuniga was killed in a hit and run accident.

"From the day I received the news to this day my life has not been the same," Mares said.

The accident happened at the intersection of Harding and Roosevelt on May 25, 2011, around 8:30 p.m. Mares believes her daughter was trying to cross Roosevelt to get to a bus stop on the other side of the road. She never made it.

A witness reported seeing a White Ford F-150 leaving the scene of the accident and that's the only information police have to go on.

"I can't stop wondering, I wake up to that thought and I go to sleep with that same thought, who could have done this?" Mares said. "This is very unfair. My daughter's life was cut short."

Zuniga left behind two teenage daughters and a son.

The family's best hope for closure is that someone will come forward with information that will lead police to the driver who struck and killed Zuniga.

"I just want to keep going and asking and pleading," Mares said. "Please, please come forward or if someone knows please call it in. They don't even have to give their name. They just have to share what they know."

Crimestoppers is offering up to $5,000 for information leading to an arrest in this case.
