This article analyzes the writings of activist women in modern-day Juárez, Mexico. I present their explanations about their own composition and delivery of two particular activist campaigns, highlighting the rhetorical strategies and practices they developed. Looking closely at these two campaigns, the article describes the rhetorical concept of coadyuvante developed by the activists in response to the rhetorical and material problem of femicide (the killing of women based on their gender) in Juárez.
