A woman accused of taking part in ecoterrorism firebombings pleaded guilty Thursday to arson and conspiracy charges on Thursday in an Oregon federal court.

Rebecca Rubin spent seven years fleeing from investigators until last year, when she surrendered to the FBI for her role with the Earth Liberation Front and the Animal Liberation Front.

She faces five to seven years in prison.

Defense attorney Richard Troberman says Rubin first tried to surrender in 2009, but California authorities at first pushed a sentence she found too long.

Investigators blame the groups for 20 fires across the West from 1996 to 2001 that did $40 million in damage. They burned a ski resort in Colorado, wild horse corrals in Oregon and Northern California, and lumber mills and Forest Service offices in Oregon.
