The Coalition to Save the Preserves (CSP) was the name used by Mark Warren Sands as a front for his arsons in the cities of Tucson and Phoenix in Arizona. In an anonymous interview with the Phoenix New Times, Sands claimed that the group was made up of young mountain bikers opposed to the spread of housing development into natural preserves in Arizona, and referred to the prominent ecoterrorist group Earth Liberation Front (ELF) as its "kindred spirits." It appears, however, that he was the lone arsonist, and acted out of personal, not environmental motives.
Authorities have arrested Mark Warren Sands in conjunction with the serial arsons, claiming that he was the man interviewed in the Phoenix New Times. Sands was caught when defacing a sign in the preserve where many of the arsons occurred, and police used DNA evidence to link him to the claims of responsibility, in the name of CSP, sent to area newspapers. Sands pleaded guilty to a number of charges against him, receiving 15-20 years in prison.
