Hayden Panettiere

Hayden Panettiere became a household name playing the indestructible cheerleader Claire Bennet in the hit sci-fi series Heroes, and later earned wide praise for her portrayal of country star Juliette Barnes in Nashville. She had been open about her struggles with postpartum depression and addiction recovery in the years before her death. She was found unresponsive at a residence in Greenville, South Carolina, and pronounced dead at 2:32 PM on August 16. She was just 36. The Greenville County Coroner later ruled her death an accident caused by the combined toxic effects of several drugs.
