Homero G?mez, 50, managed a butterfly sanctuary in the town of Ocampo in Michoac?n state, a region notorious for its violent criminal gangs.

His body was found with no apparent signs of violence near where he was seen for the last time.

Prosecutors are still investigating the case.

Rights groups had earlier said they feared that G?mez might have been targeted because of his fight against illegal logging, one of the activities that criminal gangs in the area are involved in.

G?mez was last seen in person attending a meeting in the village of El Soldado on the afternoon of 13 January, and his family reported him missing the next day. Relatives told local media the conservationist had received threats from an organised crime gang.

More than 200 volunteers had joined the search for the environmentalist and, last week, the entire police forces of Ocampo and neighbouring Angangueo were detained for questioning.

Environmental activist Homero G?mez Gonz?lez, missing for two weeks, was found dead Wednesday in a well in the Mexican state of Michoac?n.
G?mez, 50, who was last seen alive on January 13, was known for his work defending the habitat of the monarch butterfly. The State Human Rights Commission of Michoac?n had earlier said that he may have been targeted because of that work, particularly his campaign against illegal logging.

The body was found in an agricultural well in the community of Ocampo, near El Rosario Monarch Butterfly Preserve, which G?mez managed. The well was about 20 feet deep and half-filled with water, said the state prosecutors? office of Michoac?n.

An autopsy will be conducted to determine the cause of death.

According to a World Wildlife Fund report, clandestine logging of forests has greatly reduced the winter habitat of the monarch, known for its long seasonal migrations from Canada to Mexico.
