Nestor Olivos was a student and is the murder victim in A Boy in the Tree. Nestor Olivos was born to a Venezuelan ambassador, born deaf and raised as a Catholic.
When Nestor was young, he received a cochlear implant in his ear to help with his hearing, and the first sound he heard was the sound of his mother's voice, and she told him that she loved him in Spanish.
His mother was a ambassador, allowing him to be able to attend an exclusive preparatory school, and was described as being happy and content by his parents. They also mentioned he was an altar boy, and attended his Catholic church every Sunday voluntarily. His religious and awkward behavior, along with his deafness made him an social outcast, and the way he talked due to his difficulty of hearing, and spanish accent made some of his classmates classify him as a "retard". His only known friend was his three-month roommate, Tucker Pattison.
Nestor's crush Camden Destry and his roommate set up a camera near Nestor's bed. There, they recorded Nestor having sex with Camden, and Camden's mother having sex with Tucker. Being a married woman, Tucker blackmailed Camden's mother, giving him $5,000 to keep quiet. They decided to blackmail Nestor as well, threatening to tell his parents about the sex tape.
However, Nestor said a fatal sentence - he told them he would tell the headmaster about the tapes and the blackmailing. To prevent being expelled, Camden and Tucker gave Nestor ketamine before hanging him to a tree, where he died of strangulation. However, Nestor's hyoid cracked in 196.8 hours after his death when the choking and the ketamine caused his stomach to regurgitate stomach acid, weakening the hyoid until it cracked.
Eventually, his killers were found, and placed into custody by Booth and Brennan. The headmaster and head of security both lost their jobs as a result of Nestor's death, and the sheriff who collected the sex tapes resigned.
