Incident
Sheriff Thompson was shot and killed by a town marshal after an argument stemming from the sheriff closing down gambling halls in the town of Durango. The two got into an argument at one of the halls and went outside and exchanged gunfire. Sheriff Thompson was fatally wounded and the marshal was wounded. The marshal was charged with murder after it was learned that Sheriff Thompson was shot in the back. The undertaker, however, burned all of Sheriff Thompson's clothes and destroyed the evidence, resulting in the suspect's acquittal.
