A 25‑year‑old California man has died after being bitten by a rattlesnake while mountain biking, marking a rare and tragic outcome from an encounter with venomous wildlife.
The incident occurred on February 1 around 11 a.m. at the Quail Hill Trailhead in Irvine, a popular outdoor spot near the Quail Hill Community Center, according to local law enforcement.
Julian Hernandez of Costa Mesa was riding on the trail when he was bitten by the snake. Authorities rushed him to the hospital, where he fell into a coma and remained in intensive care until his death on March 4, from injuries tied to the bite, authorities said.
His family remembered him as a deeply loved son, brother, boyfriend, friend and member of his community. They have also initiated a third‑party autopsy, they told CBS News.
“Our focus right now is supporting his family through an unimaginable loss,” his family told the outlet.

While about 7,000 to 8,000 venomous snake bites occur annually in the U.S., only a handful result in death, the Centers for Disease Control and Prevention says.
Experts stress the importance of seeking immediate medical care after a bite, as venom can cause severe and potentially fatal complications if not treated promptly.
“A snake bite with venom from a rattlesnake causes significant stress on the body,” Dr. William Woo with Kaiser Permanente told KTLA. “It can cause organ shutdown. It can be really severe and we know that the effective treatment is antivenom and the sooner we can administer, the better off the patients are. It can cause a whole host of problems in the body.”
Woo also advised that anyone bitten by a rattlesnake avoid outdated or dangerous remedies, such as trying to suck out the venom or applying a tourniquet, which can worsen the injury.
“Try to stay calm, keep the heart rate nice and slow and keep the area of the bite in a neutral, relaxed position is the best thing you can do,” he said. “Do not delay that hospital care. That is of the utmost importance.”
Hernandez’s family also launched a GoFundMe to cover funeral and related expenses.
“He was strong and healthy. He was alive when he got to the hospital. His whole family was there, advocating for him every step of the way. Julian did not survive,” James Hernandez, the fundraiser’s organizer, wrote.
“We are a family that handed our son over to people we trusted and never got him back. We have questions that deserve answers, and getting those answers requires a legal fight. These funds will help cover the costs of hospital fees, memorial service, and any additional financial strain that arises from this ongoing situation. We will pursue the truth about what happened to Julian and to stand up for him.
“This is not about anger. This is about accountability. This is about making sure the next family that walks through those doors doesn’t live our nightmare,” James Hernandez said.
