The story broke here before 7am today (Perth time) and supposedly, his father found out by the radio. They said he had been sick with pneumonia and that he had not been sleeping well due to the heavy schedule of filming for his Joker role, something like one to two hours a night. It was also said that he would fly home to NY every few days to see his daughter. He was here in Perth for Christmas and was pretty much ignored - which is what he likes. He even phoned up our daily newspaper to thank them for leaving him alone during his holiday. Which was nice.
His dad came out and read a prepared statement with either his wife or ex-wife and his daughter by his side. Very dignified, especially as he did this after only four hours of the news being public.
TV and radio has been dominated by the death of (now) Perth's favourite son. I expect in the next few days there will be interviews with his friends. We have already had his former headmaster, and the casting agent who discovered him.
Most people here seem to believe that it was an accident with the sleeping tablets along with the relaxants. Very sad however it happened.
