Heath Ledger caused his own death, says father

London: The father of Oscar winning actor Heath Ledger has said that the actor caused his own death by irresponsible consumption of medicines.

The Brokeback Mountain star who died of an accidental overdose of prescription drugs in January 2008 aged just 28 was "not being responsible" with the medication he was taking, said his father Kim Ledger.

"We're all responsible for what goes into us and I blame Heath for not being responsible," said Kim who is a racing car driver, reported Contactmusic.

At the time of his death, it is believed the actor was mixing medication prescribed to him by three different doctors.

The actor's father said that he was shocked by the news of Michael Jackson's death, caused by a suspected cardiac arrest possibly caused by an prescription drug overdose, as it brought back painful memories of his son's death.

"On the day that Michael died I spoke to my daughters and former wife Sally and we all had such a down day. It's not for me to advise the Jackson family how to get through this, but what I will say is the saddest times are now, one-and-a-half years after Heath's death," said Kim.

Ledger is survived by his three-year-old daughter, Matilda Rose, who lives with her mother, actress Michelle Williams.
