SAN ANTONIO -

A family is still searching for answers four years after their loved one was gunned down at a car wash on the city's northwest side.

It happened in October of 2008 in the 4100 hundred block of Medical Drive.

The sister of Abelardo Duran, Jr., didn't want her name used in our story because she is concerned for her safety.

She said she was really close to her big brother, who she lovingly called "Junior," which made losing him even more difficult.

"I can't move on without knowing, who he was," she said. "Who took my life away from me because he was my other half. We did everything together."

Duran was killed as he was vacuuming his car.

Police said a man with a blue bandana over his face walked up to Duran and shot him several times.

Duran's sister said she knew something wasn't right because she had just talked to him.

"Something was wrong," she said. "So, my mom called him and he didn't answer and that's when the doorbell rang. That's when my heart dropped."

Duran's sister also said what's even more frustrating is that the shooting happened on a Friday in broad daylight and that she just doesn't understand why no one has come forward.

"Nobody can give us any answers and we are so frustrated," she said. "It's been so many years and we've called Crime Stoppers. We call the detectives and nobody can give us an answer."

If you have any information, call Crime Stoppers at (210) 224-STOP.
