NEW YORK — An autopsy on actor Heath Ledger was inconclusive, and more tests are needed, the New York City Medical Examiner's Office said.
A spokeswoman for the office, Ellen Borakove, said Wednesday that it will take about 10 days to complete the investigation.
There was no obvious indication of suicide or foul play, said NYPD spokesman Paul Browne, who added that cops are "investigating the possibility of an overdose."
The 28-year-old Australia-born actor's ex-fiancée, actress Michelle Williams, was flying to New York from Sweden with their 2-year-old daughter, Matilda, her father said.
"It has just broken everybody's heart in my family," Larry Williams, Michelle's dad, told The Daily Telegraph in Australia. "My heart goes out to everyone, his family, my family, we are just very saddened. The saddest thing is his daughter, whom he just loved dearly."
Oscar-nominee Ledger was found dead Tuesday at his downtown Manhattan residence, face-down and naked at the foot of his bed with prescription sleeping pills in the apartment, police said.
Ledger's father, Kim Ledger, released a statement on Australian television while surrounded by his family:
"We, Heath's family, confirm the very tragic, untimely and accidental passing of our dearly loved son, brother and doting father of Matilda. He was found peacefully asleep in his New York apartment by his housekeeper at 3:30 p.m. U.S. time.
"We would like to thank our friends and everyone around the world for their well wishes and kind thoughts at this time. Heath has touched so many people on so many different levels during his short life but few had the pleasure of truly knowing him.
"He was a down to earth, generous, kind-hearted, life-loving and selfless individual who was extremely inspirational to many. Please now respect our families need to grieve and come to terms with our loss privately."
