Parents Convicted in San Jose Fentanyl Death

A Santa Clara County jury just did something local prosecutors have been pushing toward for a while — it convicted two San Jose parents of murder after their toddler died from fentanyl exposure at home. Derek Rayo, 29, and Kelly Richardson, 31, were also convicted of felony child endangerment in the 2023 death of their daughter, Winter Rayo. Winter was 19 months old. The case matters because it pushes a neglect-and-overdose case into the category of homicide, not just reckless parenting gone horribly wrong. ### What happened? The jury found that Rayo and Richardson left Winter in a room with fentanyl and methamphetamine, and that exposure killed her on August 12, 2023, at the family’s San Jose home. Prosecutors said the couple had been using drugs around the child and that the danger was obvious enough to support implied-malice murder — basically, they knew the risk and ignored it anyway.

Murder in a case like this does not mean prosecutors had to prove the parents wanted their daughter dead. The theory was implied malice — that the parents knowingly acted in a way that was life-threatening, then kept doing it. Santa Clara County’s district attorney said this is the first time in county history that parents were charged and convicted of murdering their own child through fentanyl exposure.

Prosecutors said Winter had about 25 times the lethal amount of fentanyl in her blood, plus additional undigested fentanyl in her stomach. That matters because it suggests not just trace exposure in a contaminated room, but a massive poisoning. In other words, this was not treated as a close call about causation. (da.santaclaracounty.gov) ### Why does the 911 delay matter? Because it turns recklessness into something even harder for a jury to excuse. Prosecutors said the parents waited about 11 hours before calling 911 after Winter was already unresponsive. That gap became part of the story the jury heard — not just that the home was dangerous, but that the adults responsible for the child did not act with any urgency once the emergency was clear. (da.santaclaracounty.gov) ### Was anyone else charged? Yes — and that widens the case beyond the parents. A man prosecutors identify as the suspected drug supplier, Philip Michael Ortega, has also been charged with murder in connection with Winter’s death, and in a separate infant fentanyl death in San Jose. That tells you how aggressively the county is trying to build accountability around child fentanyl deaths, from the home to the supply chain. (ktvu.com) ### Why is Santa Clara County pushing this? Because these cases are no longer being treated as tragic accidents with no clear criminal box. Santa Clara County has spent the last couple of years bringing milestone charges after a cluster of child fentanyl deaths, arguing that some conduct crosses the line from neglect into homicide. The Winter case now gives that strategy a jury verdict behind it. (kron4.com) ### What happens next? Rayo and Richardson now face sentences tied to murder convictions — reports on the case say 15 years to life is on the table. Sentencing will come later, but the bigger change already happened: prosecutors proved that a fentanyl death inside a home can support a murder verdict against the parents themselves. ### Bottom line (jeffrosen.org) This verdict is not just about one awful death. It is Santa Clara County saying that when adults bring fentanyl into a home, expose a child to it, and then fail to respond, juries may treat that as murder. (da.santaclaracounty.gov) (ktvu.com)
