Six people, including one teenager, died at a dairy farm in Keenesburg, Colorado, 35 miles northeast of Denver, on Aug. 20, 2025.

Four of the deceased were from the same extended family. The coroner’s report confirmed they died from hydrogen sulfide exposure after a manure pipe disconnected in an enclosed pump room.
