Heath Ledger was found dead in his SoHo apartment Tuesday afternoon at 28.

New details have emerged about the sequence of events, and Mary-Kate Olsen's involvement:

According to the police, around 12:30 p.m. on Tuesday, a housekeeper, Teresa Solomon, arrived at the apartment, at 421 Broome Street in SoHo, to do household chores. At about 1 p.m., she went into Mr. Ledger's bedroom to change a light bulb in an adjacent bathroom; she found him on the bed face down, with the sheet pulled up to his shoulders, and heard him snoring.

A masseuse, Diana Wolozin, arrived to give Mr. Ledger a massage about 2:45 p.m. At 3 p.m., after Mr. Ledger did not emerge from his bedroom, with the door closed, the masseuse called him on his cellphone but got no answer. She entered the bedroom and saw him lying in bed. She took a massage table out of the closet and began to set it up near his bed. She then went over to him and shook him, but got no response. Using his cellphone, she used a speed-dial button to call Ms. Olsen in California to seek her guidance, knowing Ms. Olsen to be a friend of Mr. Ledger's.

According to the authorities, Ms. Wolozin told Ms. Olsen that Mr. Ledger was unconscious. Ms. Olsen said she would call some private security people she knew in New York, and hung up. Ms. Wolozin again shook Mr. Ledger, called Ms. Olsen a second time, and said she believed the situation was grave and would call 911.

Ms. Wolozin called 911 at 3:26 p.m. to say that Mr. Ledger was not breathing. The call occurred less than 15 minutes since she had first seen him in bed and only a few moments after the first call to Ms. Olsen. The 911 operator urged Ms. Wolozin to try to revive Mr. Ledger, but Ms. Wolozin's efforts were not successful.

Emergency medical workers arrived at 3:33 p.m., at almost exactly the same moment as a private security guard summoned by Ms. Olsen. The medical workers moved his body to the floor and then used a defibrillator and CPR, to no avail. Mr. Ledger was pronounced dead at 3:36 p.m. By that point, two other private security guards summoned by Ms. Olsen had arrived, as had police officers.

Late Wednesday, ex-girlfriend Michelle Williams and 2-year old daughter Matilda were photographed arriving back in Brooklyn from Sweden, where Williams had been filming on location.

Wednesday evening the NYPD announced that tests on a rolled up $20 bill found near Ledger's body turned up negative for drug residue. The bill had initially raised suspicions that Leger may have been using the bill to snort drugs of some kind. Authorities found six different prescription drugs in Ledger's apartment, including ones for insomnia and anxiety and an antihistamine

TMZ reports some of the prescription medications found in his apartment were "Xanax and Valium, both anti-anxiety drugs. Cops also found Ambien, along with several medications prescribed in Europe."

According to Us Weekly, the Terry Gillian production of 'The Imaginarium of Doctor Parnassus', which Ledger was partially though filming, has been scrapped and everyone let go.

Early Wednesday, the medical examiner's office said an autopsy was inconclusive and that a complete investigation would take another 10 days.

Ledger's body was taken to a funeral home Wednesday afternoon, reports In Touch Weekly. George Amato, the general manager of the Frank E Campbell Funeral Home, said, rather indiscreetly, "We have been asked to take care of the body from those who are in charge of him and to remain discreet." Tissue samples taken will stay with the medical examiner to be tested.

Wednesday morning in Australia his family gave a statement .

We, Heath's family, confirm the very tragic, untimely and accidental passing of our dearly loved son, brother and doting father of Matilda, who was found in a peaceful sleep in his New York apartment by his housekeeper at 3:30 p.m. (EST)," his father, Kim, read while accompanied by mother Sally and Ledger's sister, Katie.

"We would like to thank our friends and everyone around the world for their kind wishes at this time.

"Heath has touched so many people on so many different levels during his short life, but few had the pleasure to truly know him.

"He was a down-to-earth, generous, kind-hearted, life-loving and unselfish individual who was an extreme inspiration to many.

"Please now respect our family's need to grieve and come to terms with our loss privately."

"His mother and father heard of his death on the news. We are all devastated. The whole family is devastated over his death, and more so over having to learn of his death from the media."

Michelle Williams' father Larry called Heath "a beautiful flame":

"I think Tennyson got it right in the poem when he described someone as having died at a young age but burning the candles at both ends, and oh what a beautiful flame he made, that was Heath, what a beautiful flame he made and a great talent."

"My heart goes out to everyone in his family and my family."

"The saddest thing is his daughter whom he just loved dearly."

Ledger's ex-girlfriend, Naomi Watts, is in Sundance. All her press for her movie has been canceled because of Ledger's death.

'Brokeback Mountain' director Ang Lee released a statement:
"Working with Heath was one of the purest joys of my life... His death is heartbreaking."

Also in Sundance, Charlize Theron was stunned when told the news of his death while on the red carpet for her film.

Former flame Helena Christensen told WWD:

"I was on my way over to pay him a visit when I found out. I had just left him a message and heard his voice on the machine...He was such a special and genuine person, so extraordinarily talented because he was so raw and honest with his feelings. He was so full of life, so electric... This is immensely sad."

Fellow Australians like Mel Gibson and Nicole Kidman (best friend to Heath's ex Naomi Watts) have expressed their sadness over his passing.

A UK paper quotes Jack Nicholson as saying simply, cryptically, "I told him so."

Ledger will next be seen reprising Nicholson's role as the Joker in Batman sequel The Dark Knight, trailer here.

Warner Brothers, which is releasing the movie this summer, released a statement reading in part, "The entertainment community has lost an enormous talent. Heath was a brilliant actor and an exceptional person."

911 was called around 3:30 Tuesday afternoon, and the body was taken away by the medical examiner 3 hours later. At 6:30 pm Ledger's body left the apartment building in a black body bag on a stretcher. Here's the video.

TMZ reports Ledger was suffering from pneumonia at the time of death and that his family has been notified the death was accidental: "They are particularly distraught over media reports that he may have taken his own life. The family says he was not that kind of person."

At a press conference late Tuesday evening police confirmed that Ledger was found naked, face down in a bedroom in an apartment he was renting. He was found at 2:45 by his housekeeper and masseuse when the latter showed up for a scheduled appointment. Contrary to early reports, there were not pills strewn around, but there were pill bottles, including prescription sleeping medications. It is not known how long Ledger had been in the apartment.
