Hundreds of Lindsay Clancy supporters, many wearing pink clothing emblazoned with phrases such as “Believe,” “She Needed Help” and “Peace For Lindsay,” gathered Thursday outside the courthouse where she is on trial in the killings of her three children.

Several of the 300 women, and a few men, said Clancy’s story resonated with them and that they wanted to raise awareness about how the mental health system treats women. Clancy’s lawyer does not dispute that she killed the children, but says she should not be held criminally responsible because she was mentally ill.
