Daniel Andreas San Diego (born February 9, 1978) is an American domestic terrorist who is listed on the FBI Most Wanted Terrorists list. He is a straight edge vegan environmentalist and animal liberationist believed to have ties to an Animal Liberation Brigade cell responsible for two bombings in 2003. Andreas is also believed to have ties to Stop Huntingdon Animal Cruelty.
San Diego was born in 1978 in Berkeley, California and grew up in San Rafael, California. He attended Terra Linda High School. He took classes at College of Marin and worked at San Rafael High School's radio station, KSRH, listening to heavy metal and rock music. As a young man he gave up drugs, alcohol, meat, and milk products, taking an interest in the straight edge movement and becoming vegan.
At the time of the bombings he lived in Schellville, California, a small community outside of Sonoma, where he worked as a computer specialist. His landlord described him as "very nice and personable," mentioned his claim to be starting a new business venture of vegan marshmallows made without gelatin, and said that he had never given the impression of holding radical views on animal rights. The FBI claims this was all an act.
