Incident Summary:

10/30/1996: Three members of the Animal and Earth Liberation Fronts (ALF and ELF), Jacob Ferguson, Kevin Tubbs and Josephine Overaker, set a gasoline fire at the Oakridge Ranger Station in the Williamette National Forest in Oakridge, Oregon in the United States. One incendiary device was placed in a recycling dumpster at the southwest corner of the ranger station, and the second was planted on the outside of one of the walls of the station, causing an estimated $3,316,150 in damages to replace the building, and $1,758,039 for the contents, for a total loss of $5,074,189, in addition to a vast amount of lost research material. There were no casualties in the incident. The three selected the Oakridge Ranger Station for the target of this arson due to their familiarity with it during their opposition to the Warner Creek timber sale sometime earlier. The perpetrators were part of a group calling themselves "The Family," which proceeded to commit nearly 20 arson and ecotage attacks over a 6 year period. Upon fear of a life behind bars, Ferguson became a government informant and witness in the case, landing him a sentence of 2 years probation, and as of 2008, Overtaker remained a fugitive being sought by the government after being indicted for her involvement in the crimes. Tubbs was sentenced to 12 years and 7 months in prison for his involvement.

Additional Information Once again, Elisha Dimatteo's car was borrowed to use in this incident, but she was not present at the attack, and she was never told that her car was used to transport and plant incendiaries. It is unclear if she was part of ELF or ALF at all. Ferguson, Overtaker, and Tubbs were part of a group of about 20 members from ELF and ALF, who called themselves "The Family" and committed nearly 20 acts of arson and ecotage over a 6 year period from 1995 through 2001. By 2006, all but four of the perpetrators had been captured for their roles in various incidents, and by 2008, the 16 indicted members had been convicted and sentenced for their crimes. Four remained fugitives, including Overtaker. Ferguson received 2 years probation in exchange for his role as a government informant and key witness, and Tubbs received 12 years and 7 months in prison.
