Guadalupe was an environmental activist involved in the fight against crime in Cherán, Mexico.

Guadalupe helped to overthrow the local government in April 2011 and participated in local security patrols including those in municipal forests.  She was among the Indigenous leaders of Cherán, who called on people to defend their forests against illegal and merciless logging. Her work for seniors, children, and workers made her an icon in her community.

She was killed in Chilchota, Mexico about 30 kilometers north of her hometown of Cherá.

Anna grew up in Lewes, Sussex (UK) and, after deciding not to pursue her English degree at Sheffield University, she moved to Bristol and became a plumber.

She spent much of her time defending the marginalised and under-privileged, attending anti-fascist rallies, and offering support to the women of Dale Farm when they were threatened with eviction. A vegan and animal lover, she attended hunt sabotages and her name is honoured on PETA's 'Tree of Life' Memorial. Anna went to Rojava in May 2017 with a strong commitment to women's empowerment, full representation of all ethnicities and protection of the environment.

Anna died on March 15, 2018 when she was hit by a Turkish airstrike in the town of Afrin, northern Syria. Anna was fighting with the Women's Protection Forces (YPJ), when she was killed.
