Gómez was a tireless campaigner for the conservation of the monarch butterfly and the pine and fir forests where it hibernates. The sanctuary he managed opened in November as part of a strategy to stop illegal logging in the area, which is a key habitat for the monarch butterfly.

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

…Since 2006, 60,000 people have disappeared in Mexico, many of them believed to have fallen victim to criminal gangs who kill anyone who could interfere with their illegal activities.
