On the morning of 8 November 1913, William Gambling, a miner who had refused to join the 1913-1914 United Mine Workers of America strike against the Colorado Fuel and Iron company, was intercepted and accosted by pro-strikers as he was traveling to the dentist in La Veta. He left the dentist's office later and was picked up by a car carrying three mine guards and a driver. A volley of gunfire was aimed at the car, killing all but Gambling. At least five men were arrested by the Colorado National Guard in relation to this incident, part of the early stages of the Colorado Coalfield War.
