I was thinking of the Tejano singer
Selena as the original
Selena. She was killed by the president of her fan club while still working on her English debut album.
Jennifer Lopez played her in the biopic. Maybe it's a generational (I'm pretty sure I was still in high school when she was killed), national (more press in US/ Latin
America than England), or cultural (Even though I'm not Hispanic, I maybe remember some of things about the culture better than others because I work with Hispanic immigrants and I don't know how familiar you are with their culture).
