Evan Ellingson, the actor known for his performances in “My Sister’s Keeper” and “CSI: Miami,” passed away at 35 years old in Fontana, California. 

The San Bernardino County Sheriff’s Department confirmed the cause of Ellingson’s death as an accidental fentanyl overdose, occurring on November 5, 2023, at a sober living home in California where he was residing.

Sober living homes offer support and safe housing for individuals recovering from addiction.

Following his passing, Ellingson’s family revealed that he had been sober for three years before a prescription for opioids, following a dental treatment, led to a relapse.

Ellingson, a La Verne, California native, started his acting career as a child, gaining prominence in the 1990s with roles in “Mad TV” and “Titus.” His role in the 2009 film “My Sister’s Keeper” as Brian Dalton marked a career highlight. He retired from acting in 2010 following a series of personal struggles.

His post-acting life was challenged by drug abuse, attributed to the trauma of his older brother’s heroin overdose death. This loss initiated Ellingson’s drug use at 19 years old. 

Seeking help in 2021, he underwent treatment at River’s Edge Ranch, a California rehabilitation facility.

Despite these challenges, Ellingson remained a respected figure. His “My Sister’s Keeper” co-star, Abigail Breslin, shared on Instagram her fond memories of Ellingson, describing him as talented and kind.

Ellingson’s acting journey began unexpectedly at a skate park, leading to a commercial for Vans Company. He subsequently appeared in “Complete Savages,” “24,” and “Letters from Iwo Jima,” with his final role in “CSI: Miami.”

Ellingson leaves behind his family, including three brothers, in California.
