In the heart of Colorado, a tight-knit community is reeling from a devastating incident that occurred at Prospect Valley Dairy on the evening of Wednesday, Aug. 20. First responders were alerted to the scene around 6 p.m.

Six people who died at a Colorado dairy farm this summer were exposed to hydrogen sulfide gas, authorities said Thursday. The Weld County coroner’s office drew its conclusions from autopsies and toxicology tests. The initial findings by the Weld County coroner’s office hinted at exposure to hazardous gas, setting the stage for a detailed investigation. Authorities, including the Occupational Safety and Health Administration (OSHA) and the Weld County sheriff’s office, have noted that no criminal factors were discovered at the scene.

The tragedy took a heavy toll, claiming the lives of six individuals:

  • Ricardo Gomez Galvan, 40, dairy manager from Keenesburg
  • Noe Montanez Casanas, 32, assistant dairy manager
  • Jorge Sanchez Pena, 36, of Greeley, service manager for High Plains Robotics, a dairy service company
  • Alejandro Espinoza Cruz, 50, of Nunn, service technician for High Plains Robotics, a dairy service company
  • Oscar Espinoza Leos, 17, Espinoza Cruz’s son, accompanied his father on this work job as an intern for High Plains Robotics, a dairy service company.
  • Carlos Espinoza Prado, 29, Espinoza Cruz’s son, accompanied his father on this job, as a service technician for High Plains Robotics, a dairy service company.

DeLaval shared with Dairy Herd Management that Prospect Valley Dairy milked in a DeLaval 106-stall rotary that had been installed in 2018.
