Sylvester Ayon, a 30-year-old man, was fatally shot on October 1, 1982, while working on a ranch near Santa Ynez in Santa Barbara County. Ayon suffered multiple gunshot wounds and succumbed to his injuries at the scene. Alongside him, a 17-year-old individual was also shot but survived the attack.
The investigation into Ayon’s murder eventually led to the identification of Jose Manuel Martinez, an alleged contract killer for Mexican drug cartels, as the perpetrator. Martinez later confessed to the killing, stating that he had been hired to assassinate Ayon in retaliation for his involvement in a dancehall shooting in Durango, Mexico, in 1979, where four people were killed. Martinez claimed to be related to at least one of the victims of that shooting.
Martinez admitted that he traveled to Santa Barbara County with three other men to carry out the murder, though he refused to identify them. He ambushed Ayon while he was driving a tractor along Refugio Road, shooting him multiple times. The 17-year-old witness, identified only by initials, was also shot in the stomach but survived the attack.
For years, the murder remained unsolved, and Martinez continued his activities as a contract killer. His eventual downfall came decades later when he was linked to another murder in Alabama through a Walmart receipt found near the victim’s body. This led to his arrest and subsequent confessions regarding multiple killings, including Ayon’s murder.
Martinez was ultimately sentenced to life in prison for several murders spanning a 30-year period. His plea agreement spared him the death penalty, but he was convicted of multiple homicides, including Ayon’s, in Tulare County and other jurisdictions.
