The Supreme Court of the western Mexican state of Michoacan has ordered the release of 13 vigilantes involved in a shootout that left 11 people dead last December, officials said.
The 13 suspects, all members of the community self-defense group led by Luis Antonio Torres, surrendered to the Michoacan Attorney General's Office in April.
Hipolito Mora, founder of the vigilante movement in Michoacan, Torres and 35 other individuals were released in March for lack of evidence in the case.
Mora and his followers engaged the rival vigilante group led by Torres in a shootout in La Ruana on Dec. 16.
La Ruana is in the Tierra Caliente, a region straddling Michoacan, Guerrero and Mexico states that has been the scene of fighting among rival drug cartels.
The gunfight began when more than 80 vigilantes led by Torres, known as "El Americano," attacked the barricades manned by followers of Mora, founder of the vigilante movement that arose in Michoacan two years ago to protect communities from the Caballeros Templarios.
Six gunmen and five vigilantes, including Mora's son, died in the shootout.
Mora and his supporters surrendered to state police on Dec. 27 and were taken to a prison.
