Zucker was unable to walk or talk after the accident. The family reached a settlement with Disneyland in 2002, but the terms were never disclosed.
/*Brandon Zucker*/ was 13 years old on Monday when he died.
"He was found unresponsive by his father at their home in Anaheim," said Jim Amormino from the O.C. Sheriff's Dept.
Zucker was taken to St. Joseph Hospital, then transferred to Children's Hospital Orange County, but he was declared dead at 1:15 a.m. Monday.
An autopsy was performed, but authorities say the exact cause of his death has yet to be determined.
Zucker had suffered a variety of medical conditions since the accident, according to Amormino.
"It's become a coroner's case because of that accident, and the age of the victim," he said.
About a year after the accident, Disneyland changed several of its safety procedures, including teaching employees to dial 911 directly if an accident occurs and staffing paramedics in the park.
Disneyland said in a statement, "We are saddened to learn of the passing of Brandon Zucker and our thoughts and prayers are with his family at this difficult time."
Disney is the parent company of ABC7.
