A magistrate is scheduled to try Arizona Parks Director Bryan Martyn on Oct. 18 on a misdemeanor disorderly conduct charge stemming from a March 10 shoving dispute at a park.

Martyn tells the Arizona Republic that he believes the case is going forward only because of his dispute with Florence Mayor Tom Rankin over a controversial copper-mine project in Florence.

Martyn is accused of pushing another person after the man made statements against Martyn on Facebook and on a local radio station.

Martyn and Rankin have engaged in a dispute over Curis Resources' attempt to develop an underground mine in Florence.

Martyn supports the mine and previously worked for an organization partly funded by Curis that attacked Rankin in the last mayoral race.

Rankin opposes the mine.
