The Weld County Coroner’s Office has released the names of six victims killed in a tragic incident at Prospect Valley Dairy east of Keenesburg on August 20. Authorities believe the men were exposed to gas while working in a confined space.
The deceased include residents from across Northern Colorado:

Autopsies have been completed, though the official cause and manner of death are pending. Early reports suggest that gas exposure in a confined space was the likely cause, though testing continues to determine the specific gas involved.
Community Impact
Among the victims was a student at Highland High School in Ault, part of the Weld RE-9 School District, bringing grief to both classmates and educators. Counseling and support services have been made available to students and staff.
The loss is reverberating across Weld County communities, including Greeley, Evans, Nunn, and Keenesburg, where families and neighbors are mourning the sudden deaths.
