A.B. played the bass, Suzette Quintanilla was on the drums, and Selena's husband, Chris Pérez, was the guitarist. Sadly, Selena was killed in March 1995 by Yolanda Saldívar, the president of her fan club. Following the tragedy, Abraham went on to preserve her legacy. He even opened up about his late daughter in the new Netflix documentary Selena y Los Dinos, which came out in November. Recalling the first time he brought Selena to a record label in San Antonio, he said: "At first, they were skeptical because it's a girl - and a young girl. I said, 'Well, let's give it a try one time,' and we recorded a song. She was signed immediately, and the rest is history. We are sending condolences to the Quintanilla family during this difficult time. Rest in peace, Abraham...
