RIVERSIDE — A man who supplied fentanyl-laced pills that caused the death of his 29-year-old friend in Norco pleaded guilty Friday to voluntary manslaughter and other offenses, even as jurors were deliberating whether to convict him of second-degree murder. Jacob Austin Parr, 45, admitted the manslaughter count, as well as two counts of transportation or sale of controlled substances, under a plea agreement with the Riverside County District Attorney’s Office. In exchange for his admissions, prosecutors dropped the murder charge against him. The plea deal was announced Friday morning as jurors resumed deliberations following a weeklong break granted by Riverside County Superior Court Judge Timothy Hollenhorst. The panel had already deliberated three days around the holidays. Hollenhorst dismissed the jury after the plea bargain was presented and scheduled a sentencing hearing for Thursday. Parr is being held without bail at the Byrd Detention Center. He supplied the pills that caused the death of Isaak Quintin Ruiz. According to a defense brief filed last April, Parr and Ruiz had been friends for several years, but Parr had only sold narcotics to the victim periodically in the four months prior to his death. Testimony by sheriff’s investigators during the defendant’s 2023 preliminary hearing indicated Ruiz had attempted to kick his drug habit, trying to detox in a rehabilitation program, but he continued to “struggle with opiates.” “The decedent’s girlfriend … told police that he struggled with addiction and went from using heroin to fentanyl,” the brief stated. “She said that it was difficult for him to resist smoking whatever substance he had in his possession.” Court papers said Parr was endeavoring to put his life on track and quit using or selling drugs, but when Ruiz couldn’t find a seller, he turned to the defendant. “(Ruiz) rejected offers for less lethal opiates and said he would save his money for `fetty,”‘ the brief said. In a text exchange between the victim and defendant in February 2022, Parr warned, “You gotta be careful, bro’. This (expletive) will kill you if you haven’t used in a while,” according to the narrative. At one point, before selling fentanyl to Ruiz, the defendant offered him Narcan, an opioid antagonist that can arrest the effects of fentanyl and save victims who have taken a potentially lethal amount, the brief said. Ruiz didn’t accept. On the night of April 22, 2022, Parr met Ruiz at a Norco restaurant, selling him an undetermined amount of fentanyl, then the two left in Parr’s car and drove to a nearby 76 station on Sixth Street, where Ruiz stepped into the men’s room and locked the door, according to investigators. Parr drove away. The victim consumed the fentanyl he’d purchased and passed out on the floor. He was in there for two hours before the clerk finally unlocked the door to check on him, discovering him dead, according to investigators. Detectives ultimately identified Parr as the person who sold the fentanyl to the victim, culminating in his arrest on July 12, 2022. The defendant has a prior conviction for misdemeanor DUI. Since February 2021, the District Attorney’s Office has charged over 30 people countywide in connection with fentanyl poisonings. In November 2023, prosecutors closed the books on the county’s first fentanyl murder case to go before a jury, culminating in the conviction of 34-year-old Vicente David Romero, who was sentenced to 15 years to life in prison for the 2020 death of a Temecula woman. Public health statistics show there were 550 known fentanyl-related fatalities countywide in 2023, a 9% increase from 2022, when there were 503. Data from 2024 hasn’t been published. Fentanyl is manufactured in overseas labs, principally in China, according to the U.S. Drug Enforcement Administration, which says the drug is smuggled across the U.S.-Mexico border by cartels. It’s 80-100 times more potent than morphine and can be mixed into any number of street narcotics and prescription drugs, without a user knowing what he or she is consuming. Ingestion of only two milligrams can be fatal.
