Some people say he seemed normal; others say he appeared to be high or "out of it"

He was found dead Sunday morning with a syringe in his arm, sources say

The day before he was found dead in a Manhattan apartment, actor Philip Seymour Hoffman went to his favorite coffee shop for a four-shot espresso.

That night, he met two others for dinner at a West Village restaurant.

Nothing appeared out of the ordinary -- either that morning or that night.

But some of those who interacted with Hoffman during the day Saturday paint a different picture.

The mother of his children said he appeared high. A passerby who stopped to say hi to him said the actor appeared "out of it."

In New York's Greenwich Village neighborhood, where Hoffman lived, it was common to see him riding a bicycle and walking his children to the public school they attended.

5 p.m. -- Hoffman is spotted walking along Greenwich Street by Paul Pabst, executive producer of the syndicated "Dan Patrick Show." Pabst is with his wife and his sister, who plucks up the courage to say hi to Hoffman.

Saturday evening -- Hoffman has dinner with two companions at Automatic Slims, a restaurant and bar in the West Village that he frequently visited.

Around 8 p.m. -- O'Donnell talks to Hoffman on the phone. He again seems to be high, she later tells authorities. After their conversation, no other contact with Hoffman has so far been confirmed.

Between 8 and 9 p.m. -- Hoffman withdraws a total of $1,200 from an automated teller machine in six transactions at a supermarket near his West Village home, two law enforcement sources say, citing bank records.

11 a.m. -- O'Donnell asks a Hoffman friend, playwright David Katz, to check on the actor. Katz and another person subsequently go to the fourth-floor apartment, where they find him dead, lying on the bathroom floor with a syringe in his left arm. He is wearing shorts and a T-shirt, his eyeglasses still resting on his head, according to law enforcement sources familiar with the inquiry.

Around 11:30 a.m. -- Police are called. They arrive at the apartment shortly afterward. O'Donnell is told what has happened. She quickly picks up their son from the playground and brings him home.
