Alec Baldwin has been photographed in Santa Fe, New Mexico, with Halyna Hutchins' husband and 9-year-old son.
In one of the photos, Baldwin can be seen hugging Matt Hutchins, the cinematographer's husband.
Halyna Hutchins died last week on the set of western movie Rust, when the 63-year-old star accidentally shot her with a gun that was not meant to be loaded.
Baldwin and the Hutchins family were pictured in Santa Fe, near where the tragedy happened.
Wearing black and looking sombre, Baldwin hugged both Matt and his son Andros.
A witness told the New York Post the actor looked like "a beaten man".
"His body language was [that] of a beaten man, he was slumped, he looked aged.
"I thought at first he grabbed the (luggage) cart to help him walk because he looked so down."
Matt Hutchins, who had already posted a tribute to his late wife, has since posted new photos of Halyna.
Taking to Instagram, the grieving husband shared new family shots, with the caption: "We miss you, Halyna".
Baldwin himself earlier took to social media to describe his heartbreak.
"There are no words to convey my shock and sadness regarding the tragic accident that took the life of Halyna Hutchins, a wife, mother and deeply admired colleague of ours. I'm fully cooperating with the police investigation," Baldwin wrote on Twitter. "My heart is broken for her husband, their son, and all who knew and loved Halyna."
The cinematographer's father, Anatoly, says her family is heartbroken and struggling to cope.
"We still can't believe Halyna is dead and her mother is going out of her mind with grief," he told The Sun.
"But I don't hold Alec Baldwin responsible – it is the responsibility of the props people who handle the guns."
Anatoly is now fighting for his wife Olga and daughter Svetlana to fly to the US to comfort Matt and Andros.
