On August 22, 1985, the 29-year-old Childs and his girlfriend at the time were arrested for possession of a 10-inch artillery mortar simulator. while a friend of Childs, John, claimed that he had sold a Luger to Childs sometime prior to the killing. John then directed the authorities to an area where Childs had fired several rounds into some trees. At the site, several shell casings were located, which, following a ballistic examination, were conclusively linked to the Luger used by Childs. In early April 1986, under the terms of the plea deal, some of the charges against Childs' girlfriend were dropped, and she was given a sentence of 5 years in the women's correction system. On January 15, 1987, Terry Childs' trial began. The Santa Cruz County Attorney's Office insisted that the defendant was a sadist who had committed the murder with extreme cruelty, taking pleasure in torturing his victim. At one of the court sessions, a forensic expert brought by the prosecution stated that nine out of the fifteen bullets had hit the victim, most of them in the areas of the arms, thighs and abdomen. According to his statement, the victim was conscious and tried to crawl away, before Childs fired one final fatal shot that hit her in the head. The prosecution's main witness was Childs' girlfriend at the time of the murder, who reaffirmed her initial testimony and retold the events to the court. John, who was an accomplice in the robbery that led to Sigala's murder, refused to testify in court against Childs, but his father, J. Sr., claimed that he had seen his son sell the pistol to Childs. Childs himself insisted on his innocence, claiming that he was mentally ill. To reinforce his claims, his lawyer brought in Dr. David Gorelick, a neurologist who worked at a veterans hospital in
Los Angeles, who stated that the defendant's long-term drug abuse resulted in him developing
paranoid schizophrenia. A number of Childs' acquaintances also stated that shortly before his arrest, he had acted in an aggressively paranoid or outright hostile manner. Childs' lawyer, Tony Salitich, also proposed that the girlfriend's testimony should be considered unreliable, as she herself was a drug abuser. On February 4, 1987, Terry Childs was found guilty of the murder via jury verdict, after which the court sentenced him to life imprisonment with the right to parole after serving at least 41 years of his sentence. Reportedly, in a fit of anger, Childs had asked a friend of his to smuggle in an
Uzi so he could shoot up the courtroom. == Subsequent confessions ==
