CALIFORNIA ? Two men who had sex with a transgender teen and then discovered she was biologically male were convicted Monday of her murder, but cleared of hate crime charges.

Michael Magidson and Jose Merel, both 25, face mandatory sentences of 15 years-to-life in prison for second-degree murder in the killing of Gwen Araujo, who was beaten, tied up and strangled.

The jury was deadlocked in the case of a third man, Jason Cazares, 25, marking the second time a mistrial was declared in his case.

Araujo, 17, was born a boy named Edward but grew up to believe her true identity was female. The defendants, who knew her as Lida, met her in the summer of 2002. Magidson and Merel had sexual encounters with her, experiences that fueled suspicions about Araujo’s gender.

An autopsy found that Araujo died of asphyxiation associated with head injuries.
