Cardona plays the Alex Guzmán in the series. And let’s just say he plays Alex well. Although having only a few accreditation titles –Narcos and The snitch cartel– he amazes fans with his heartbreaking scenes in Who killed Sara ?.

Venezuelan actor Alejandro Nones plays Rodolfo, the eldest Lazcano and Sara’s ex-boyfriend who appears to have murdered her (at least in the first few episodes). A known model, Nones has appeared in a few Mexican telenovelas with Who killed Sara? being his biggest role to date.

Perhaps the most famous performer on Who killed Sara?, Carolina Miranda is a Mexican actress known for her work in soap operas and telenovelas. Although somewhat unknown to the American Hollywood scene, Miranda has appeared in numerous plays, reality shows, web series, and scripted films for Mexican audiences. She even won awards such as Best Actress at Los Mexico’s Awards and The Produ Awards as a Breakthrough Actress. She plays Elisa Lazacono, the youngest of the children and Alex’s lover.

Eugenio Siller portrays Chema Lazcano, the disgraced middle child in a same-sex relationship. Siller first began acting in commercials and musical pieces until he managed to play a blind man in a Mexican soap opera. He has since built a versatile career playing challenging characters, as a model and even starting a career as a singer.

Similar to her other co-stars, Fátima Molina is also a bit unknown on the American scene. She has a few acting roles in Mexican dramas such as Diablero or La Doña. In Who killed Sara?, she plays the role of Clara, Chema’s surrogate mother and Marifer’s little sister.

The manipulator and avenger César Lazcanois is played by the Spanish actor Ginés García Millán. Millán’s performance as Patriarch Lazacnos is so powerful that sometimes you forget he’s even playing. Producer and actor, Millán has equal theatrical and cinematographic experiences.

Claudia Ramírez embodies the cunning and sly Mariana Lazcano, the matriarch of this criminal family and the mother of Chema, Rodolfo and Elisa. Ramírez’s performance as the innocent and gentle Mariana is so compelling that fans initially assume Caesar is the series’ villain until later episodes reveal Mariana as the true mastermind. Throughout his 20-year career, Ramírez has starred in numerous movies and TV shows, including Streeters and Idol.

What better man to play the sadistic Sergio Hernández, Caesar’s right-hand man, than a Mexican actor with over thirty years in the business? Juan Carlos Remolina plays Sergio, and he plays him well. It’s no surprise that this actor has a few accolades – including an Emmy – to his name.

You might recognize Héctor Jiménez from the 2006 comedy film Nacho Libre. But his days of playing wrestlers are over. In Who killed Sara?, Jiménez stars Elroy, the adopted son and faithful disciple of Mariana. As well as staring in this Netflix drama, you can find Jiménez producing movies or acting as a stage clown.

Litzy surprised us all with her portrayal of mentally unstable and heartbroken Mafier, Sara’s former best friend and Clara’s sister. Who could have expected that Marifer had “killed” Sara? Surely not from fans, because Marifer’s Litzy performance was just so compelling – no one expected her to be murder. If you want to see more of Litzy’s roles, you can find her in Quiéreme Tonto or Al Otro Lado del Muro.

Luis Roberto Guzmán plays Lorenzo, Chema’s longtime partner who is a lawyer. Most of Guzmán’s works consist of Mexican telenovelas, including El Pantera.
