A production manager who was helping to move platforms used for staging at Jacob’s Pillow, a celebrated dance center in Becket, Mass., was killed after the load toppled on Friday afternoon, according to the center and the authorities.

The person killed, identified by Jacob’s Pillow as Kat Sirico, was rolling a dolly with the help of an intern to transport the platforms for theater staging across the property, the Berkshire District Attorney’s Office said in a statement on Saturday.

What happened was determined to be a workplace accident, according to the statement, and criminal charges were not expected to be filed.

The two people moving the platforms lost control of the dolly they were using when they began rolling it down a slope, according to the district attorney’s office.

Sirico, who used the pronouns they/them, according to their LinkedIn profile and the center, tried to regain control of the dolly but tripped and fell, and the dolly ran Sirico over, the district attorney’s office said.

The platforms on the dolly fell onto Sirico, the statement further said. Bystanders attempted lifesaving measures and emergency medical workers and members of law enforcement also responded to the scene.

In a statement on Saturday, the center called Sirico’s death “a tragic accident.” The Occupational Safety and Health Administration was investigating, according to the statement.

Jacob’s Pillow announced that all performances and events at the center were canceled from Friday through Sunday.

Sirico was part of the alumni of Jacob’s Pillow, the center said, and had been working since February as a production manager for the Dance Festival at the recently reopened Doris Duke Theater.

Sirico had previously worked for the Dance Festival, including last year as an event production manager. They were also a production intern two decades ago and had been an independent contractor for Jacob’s Pillow, a spokesman for the center said.

Pamela Tatge, the executive and artistic director for Jacob’s Pillow, said in the statement that Sirico was a “hugely devoted leader on our team.”

“Their spirit, generosity, and dedication touched the lives of many,” Ms. Tatge added.

Jacob’s Pillow, which was founded in 1931, has an expansive campus of two indoor theaters, stages and studios across more than 200 acres in the picturesque Berkshire hills.

According to its website, it receives more than 100,000 visitors each year and employs 53 full-time year-round staff members, 100 seasonal workers and 25 interns.

The Dance Festival at Jacob’s Pillow is the oldest in the United States. It runs from late June through late August. The festival was in week six when performances and events were canceled after Sirico’s death, according to the Jacob’s Pillow website.

The center had recently recovered from the destruction of the Doris Duke Theater, which burned down in November 2020. The theater reopened last month.
