Matthew Hutchins is paying tribute to his late wife, Halyna Hutchins, in his first Instagram post since her death.

Taking to social media for the first time since Halyna, 42, was killed on Thursday in an accidental shooting on the set of the movie Rust, Matthew shared a brief message about his late wife. He also posted a few images of the couple and their 9-year-old son, Andros.

Matthew kept his caption short and sweet, simply writing,“We miss you, Halyna!” Unsurprisingly, the widower received an outpouring of support in the comments section, with many wishing Hutchins “rest in peace” following such a tragic accident.

“This post is so beautiful and says it all. She was so smart, talented, kind, confident and unbelievably brave,” one fan commented. “I am still very shocked speechless, and endlessly sorry for your loss. Please know that my thoughts are with you.”

Another echoed that same sentiment, writing, “May her precious memory be a blessing for you❤️😢.”

Halyna Hutchins along with director Joel Souza were accidentally shot on Thursday, October 21 by Rust star and producer Alec Baldwin during a camera test at the Bonanza Creek Ranch set in New Mexico.

The cinematographer died from her injuries after being airlifted to the University of New Mexico Hospital. Souza, 48, was treated at the Christus St. Vincent Medical Center in Santa Fe and was released on Friday.

Shortly after news of the tragedy went public, Matthew told Insider that “there are words to communicate the situation.”

“I am not going to be able to comment about the facts or the process of what we‘re going through right now, but I appreciate that everyone has been very sympathetic,” he explained. “I think that we will need a little bit of time before we can really encapsulate her life in a way that is easy to communicate.”

That same day, in an interview with Daily Mail, Matthew said Baldwin has been “very supportive” about the tragedy when the two spoke following the incident.

Baldwin confirmed in a statement that he had been in touch with Matthew, adding that he was “fully cooperating” with police as they investigated the incident and how it occurred.

“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,” Alec wrote. “My heart is broken for her husband, their son, and all who knew and loved Halyna.”
