Stephen James Murphy, 43, was arrested without incident Wednesday at his home in Arlington, Texas, after being named in a criminal complaint filed last week in U.S. District Court, said FBI spokeswoman Laura Eimiller. According to the complaint, the Pasadena Fire Department responded to a construction site on Sept. 19, 2006, and found what it described as a 'crude incendiary device' constructed from cigarettes that had failed to ignite. Authorities said DNA found on the cigarettes matched Murphy's DNA, which was in a California Department of Justice database in connection with a previous arrest. The following day, workers at the site could not start a tractor that was marked with a note written in permanent marker: 'ANOTHER TRACTOR DECOMMISSIONED BY THE E.L.F,' federal officials said. Investigators found that someone had tampered with the tractor's ignition system. The Earth Liberation Front, a radical environmental group that has used vandalism and violence, including arson, to further its cause, sometimes identifies itself as 'ELF.' A federal judge in Texas denied bail for Murphy on Thursday and ordered that he be transferred to Los Angeles to face charges in connection with the case.
