At approximately 4:30 p.m. Thursday a semi truck hauling roughly 100 cows overturned on Interstate 25 in Cheyenne.
The Wyoming Highway Patrol did not have an update on the condition of the semi driver, but did note that 20 cows had died in the crash. Authorities worked Thursday night to round-up about 30 additional animals.
The remaining 50 are currently being sought by Cheyenne Animal Control and law enforcement. The Cheyenne Animal Shelter shared some photos of the efforts.
