A sheep rustler is a person who illegally steals sheep from farms or ranches. This crime has been common in rural areas where sheep farming is prevalent. Rustlers often operate at night to avoid detection, using various methods to capture and transport the stolen animals. Historically, sheep rustling has been associated with the American West, where conflicts over land and livestock were frequent. The term is also linked to the broader concept of livestock theft, which can involve other animals like cattle. Law enforcement agencies take sheep rustling seriously, as it can significantly impact farmers' livelihoods.
