The Killing Of Pat Garrett Carl Adamson was the third man present when the lawman died.

Carl Adamson was a New Mexico rancher who agreed to buy property from legendary lawman Pat Garrett in 1908.  In fact, Adamson was riding in a buggy with Garrett when Pat was killed on February 29, not far from Las Cruces.  

Adamson—the only witness—backed up the story that Wayne Brazel shot Garrett in self-defense.  He testified as much to a grand jury. But Adams didn’t give evidence at the trial; he was under arrest for illegally smuggling Chinese workers into the U.S. from Mexico.
