The report states that Ellingson passed away on November 5 in Fontana, California. His cause of death is listed as "pending" by the coroner's office, therefore it has not been confirmed.
Michael Ellingson, Ellingson's father, told TMZ that his son Evan had struggled with drugs in the past but had recently been doing better. Evan's body was discovered at a sober living facility.
Ellingson began his acting career as a child, making many TV appearances in the early 2000s. He is most renowned for playing Cameron Diaz's eldest child, Jesse Fitzgerald, in the 2009 film "My Sister's Keeper," which was adapted from the same-titled Jodi Picoult novel.
