A production manager who was helping to move platforms used for staging at Jacob’s Pillow, a celebrated dance center in Becket, Massachusetts, was killed after the load toppled Friday afternoon, according to the center and 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, the Berkshire district attorney’s office said in a statement 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.
