Newark, Calif. ? A 23-year-old man who pleaded guilty to manslaughter in the killing of a transgender teen was sentenced to 11 years in prison on Friday.

Jaron Nabors, of Newark, Calif., pleaded guilty to voluntary manslaughter early in the case. He admitted to aiding and abetting Gwen Araujo’s murder and showed authorities where the teen’s body was buried.

“There’s nothing that can be done that will take away from the immense pain of the family of the victim, but Jaron did the best he could after he had participated in this horrible event,” Nabors’ attorney, Annie Beles, said after the hearing.

Araujo, 17, was beaten, tied up and strangled on Oct. 4, 2002, after men she had sexual encounters with learned she was biologically male, according to authorities.

Araujo was born a boy named Edward but grew up to believe her true identity was female.
