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.
