Hipolito Mora founded a vigilante force to fight drug traffickers in Michoacan which later become part of an official rural police force that received guns, uniforms and pay from the government.
On December 16, Mora's group had a shootout with a rival rural police force led by Luis Antonio Torres, better known as "Simon the American," that left 11 people dead in the remote mountain town of La Ruana, Michoacan.
Judge Maria Consuelo Lopez Ramirez yesterday said there was sufficient evidence against Mora and his followers of their involvement in 10 homicides during the shootout to merit the launch of proceedings.
Mora's son was killed in the clash, the only death not attributed to his group.
What sparked the shootout at a roadblock was unclear, with each side blaming the other. Authorities have said it stemmed from "animosity and conflicts between self-defense groups."
