Costa Mesa, California – A Costa Mesa Eagle Scout and mountain biker whose rare fatal rattlesnake bite underscores trail safety and the limits of even prompt medical care.Julian Enrique Hernandez, 25, of Costa Mesa, California, died on March 4, 2026, more than a month after being bitten by a rattlesnake while mountain biking at Quail Hill Trailhead in Irvine.

The Orange County Coroner’s Office listed the cause as an animal bite. His death is one of the rare fatal venomous snakebites in the United States—typically only about five per year amid 7,000–8,000 bites annually, according to the Centers for Disease Control and Prevention.

What Happened on the Trail
On the morning of February 1, 2026 (around 11 a.m.), Hernandez was mountain biking near the Quail Hill Community Center, the start of a popular roughly 2-mile trail loop in Irvine Ranch Open Space. Accounts from family (via GoFundMe organized by his brother James Hernandez) and Irvine Police Department Public Information Officer Kyle Oldoerp indicate he stopped—either to wait for a companion/friend or to step aside and let others pass while riding with his father.
While adjusting or unclipping a shoe, he lost his balance, fell into brush, and was bitten on the leg by a rattlesnake (reports point to a Southern Pacific rattlesnake common in the area)

Some reports note he attempted to ride for help before the venom took effect. Orange County Fire Authority crews responded promptly, transported him to a hospital while he was still alert, and he received antivenom and intensive care. He later fell into a coma, remained in the ICU for over 30 days, and did not recover.

Family members described him as strong and healthy. They stayed by his side throughout, advocating for his care. In a GoFundMe update they wrote of handing their son over to trusted caregivers and never getting him back; they have initiated an independent third-party autopsy seeking greater clarity. Funds raised have supported hospital costs, memorial expenses, and related needs.

Who He WasHernandez was identified by local scouting connections (including Eagle Scouts Troop 106 in Costa Mesa) as an Eagle Scout and active community member. Loved ones remembered him as a deeply cherished son, brother, boyfriend, and friend who impacted many. He enjoyed outdoor activities such as mountain biking. Public coverage has emphasized his character and the shock of the loss given how rarely such bites prove fatal.

Local authorities and outdoor communities have used the incident as a reminder of vigilance on Southern California trails.
