 -- Brittany Maynard, the 29-year-old woman who became the face of the death with dignity movement since she was diagnosed with brain cancer, has ended her life, according to an organization she worked with closely.

Maynard took lethal medication prescribed by a doctor and died late Saturday, "as she intended -- peacefully in her bedroom, in the arms of her loved ones," Sean Crowley, a Compassion & Choices spokesman, said in a statement today.

"We're sad to announce the passing of a dear and wonderful woman, Brittany Maynard. She passed peacefully in her bed surrounded by close family and loved ones," Compassion & Choices, a non-profit that works to improve care and expand the choices for people at the end of their lives, said on its Facebook page.
