Ariana Huemer is an HSUS "cruelty case manager" based in Oakland, California. She wrote HSUS's online coverage of NFL quarterback Michael Vick's 2007 dogfighting conviction. Two years later, she also covered Vick's return to his hometown of Newport News, Virginia—as part of an HSUS-sponsored publicity tour of U.S. schools.
In 2003, the FBI performed a court-ordered search of an automobile belonging to Daniel Andreas San Diego, a federal fugitive on the FBI's "Most Wanted Terrorists" list. San Diego is wanted for the 2003 bombings of two California biomedical research companies—violent crimes allegedly carried out because the companies had business ties to a laboratory that performs research on animals.
Along with chemicals and other bomb-making materials, the FBI found a $100 check written to San Diego by Ariana Huemer.
Huemer and several other animal activists were later subpoenaed to testify before a federal Grand Jury in San Francisco that was investigating the case. She appeared before the Grand Jury in January 2006, pleaded the Fifth Amendment, and refused to testify. She was reportedly granted immunity, but still refused to tell the Grand Jury anything she knew about Daniel Andreas San Diego.
In addition to her writing duties with HSUS, Huemer edited a 2006 history of the eco-terrorist Earth Liberation Front (ELF), a book written by the group's former chief spokesperson.
