Summary: Announced, no further details
well, found a little:
8:33PM PT – Law enforcement sources confirm police responded to an incident involving Hayden today and there is currently an open investigation.
8:20PM PT – A source close to Hayden tells TMZ … she recently had been complaining about back pain in the past year.
she had lot problems in her personal life for the last 10+years, alot of mental ones. i wouldnt be surprised if tha tlead to her death. after heros ended, all we heard about her was her drama, problems, almost nothing about her career after.
Nashville was quite successful, I believe and she was more of a central character, where heroes was more an ensemble. She had her issues, but her career continued.
