Yesterday, Kim Ledger visited his son's apartment on Broome Street. After Heath Ledger had been found dead in a Soho loft last week, mourners have left letters, flowers and other tributes to the 28-year-old actor. The building staff had collected the items and kept them in the basement; the building super told the Post Kim Ledger said the mementos were "beautiful."

Kim Ledger, who spent an hour in the apartment, was accompanied by NYPD detectives and indicated he might return to collect some belongings. Yesterday, it was reported that a man impersonating Kim Ledger had duped a funeral home into providing hotel rooms at the Carlyle as well as spoken to a number of celebrities and the NYC ME's office. TMZ had audiotape of the impersonator calling Fox 5 (the police are still reportedly investigating).

And US Magazine is reporting that Ledger was taken to rehab in 2006, but refused to enter. His then girlfriend/fiancee and mother of his child Michelle Williams had driven him to Malibu's Promises treatment center, but Ledger "refused to check in, instead swaying her with a pledge to clean up." Toxicology reports are expected later this week or next.
