## Actress found dead at 36
Hayden Panettiere, star of Heroes and Nashville, was found unresponsive at a South Carolina residence last month.
## Autopsy reveals drug combination
The Greenville County Coroner's Office found fentanyl, Xanax, methocarbamol, and quetiapine in her system. Her death was ruled accidental with no signs of trauma.
## Addiction began at age 16
Panettiere said a member of her professional team gave her a "happy pill" for energy during a Heroes red carpet event when she was 16, opening a door to lifelong addiction.

> I had no idea that this was not an appropriate thing, or what door that would open for me when it came to my addiction.
## Escalating dependence over time
As she got older, Panettiere said drugs and alcohol became something she almost couldn't live without. She published a memoir months before her death discussing her addiction and postpartum depression.

Panettiere's brother Jansen died at 28 from a heart condition, but had also struggled with heroin and cocaine use. She revealed this in her memoir.
## Fentanyl's deadly toll
Fentanyl, the synthetic opioid found in her system, has killed hundreds of thousands of Americans over the past five years alone.
## Key takeaway

Hayden Panettiere's death was ruled an accidental overdose involving fentanyl and multiple other drugs; she had previously spoken openly about lifelong struggles with addiction that began at age 16.
