A Texas woman whose case received support from activists and celebrities after her family alleged she was a victim of sex trafficking has been sentenced to 12 years in prison for her role in a fatal robbery, the Dallas County District Attorney’s Office announced Monday.

Zephaniah “Zephi” Trevino, 20, was charged in connection with the death of Carlos Arajeni-Arriaza Murillo, 24, who was fatally shot during a 2019 robbery at an apartment in Grand Prairie, Tex. Her attorney said Trevino pleaded guilty to murder and aggravated robbery to avoid risking a possible life sentence.

Trevino was prosecuted as an adult, despite being 16 at the time of the crime. She will concurrently serve a 12-year sentence for murder and a five-year sentence for aggravated robbery, according to a statement from the district attorney’s office.
