Michelle Williams still asks why Heath Ledger died

NEW YORK (Reuters) - Actress Michelle Williams says she still can't find the meaning behind Heath Ledger's death three years ago, in a rare interview talking about the late father of her child who died of a prescription overdose.

Williams, who since the actor's death in New York in January 2008, has remained mostly quiet in interviews about her former partner, told ABC news show "Nightline" this week she could understand why the public was curious about her grief, but still could not understand why Ledger died.

"I've found meanings around the circumstance but the actual event itself still doesn't have a ... I can't find a meaning for it," she said with tears in her eyes.

The 30 year-old actress, whose romance with Ledger blossomed on the set of "Brokeback Mountain" in roles for which they both received Oscar nominations (he won supporting actor), said she had found "meaning in things and people and relationships that have sprung up and friendships that have strengthened.

"I can find a lot of meaning in that, but not in why," she said.

Williams had split with Ledger when he died but was still sharing duties raising their daughter. To deal with her grief, she said she read "The Year of Magical Thinking" by Joan Didion, the Pulitzer-Prize winning account of Didion's year following the death of her husband.
