When most Americans think of abortion, they frequently refer to the Roe v. Wade Supreme Court case that legalized it. However, it is a lesser known case that helped make abortion so prevalent: Doe v. Bolton.

Sandra Cano, the “Mary Doe” of the infamous case,never wanted an abortion. But, like Norma McCorvey, the Roe of Roe v. Wade, she was used to topple pro-life laws across the country. Now, Cano was in the hospital in poor health.

Can had been critically ill in a hospital outside of Atlanta dealing with throat cancer, sepsis and heart failure. Today, she passed away.

As one pro-life activist reports:

Today, Sandra Cano, Mary Doe in the Doe v. Bolton Supreme Court Decision a companion decision to Roe v. Wade has lost her battle with cancer. According to her friends on Facebook- she passed away September 30, 2014 A post written on Cano’s Facebook page after her death reads, “She is more happy than anyone I know to be gracing heaven. If anyone knows how to enjoy it…it’ll be Sandra. WE love you, Sandra!!! Your name lives on as someone fought for the life of a child…not the right to kill it!!! Love you!!”

As the companion case to Roe v. Wade, the Doe decision saw the high court define “health” to include “all factors — physical emotional, psychological, familial, and the woman’s age” that may prompt someone who have an abortion. Pro-life groups have since opposed health exceptions in any pro-life legislation because it would essentially all for all abortions to remain legal.

Cano eventually filed a lawsuit seeking to overturn Doe v. Bolton but was unsuccessful.

Kristan Hawkins of Students for Life of America told LifeNews:

Most young adults in this generation don’t know about the companion case to Roe v. Wade – Doe v. Bolton, in which Sandra Cano was Mary Doe. Both cases were instrumental in launching an entire movement dedicated to overturning both decisions and making abortion illegal. Doe v. Bolton specifically defined “health” as “all factors — physical emotional, psychological, familial, and the woman’s age” which meant that a woman could essentially have an abortion for any reason whatsoever and claim it was for her “health.” Sandra Cano became pro-life however and she wanted nothing more than to see her case overturned. Her fight is one that that Students for Life of America will continue to fight for her. We pray for her soul and thank her for her fight to end abortion in this country. May she rest in peace.

Father Pavone of Priests for Life recalled that during a 1997 event at the National Memorial for the Unborn in Chattanooga, TN., Sandra said: “I pledge that as long as I have breath, I will strive to see abortion ended in America.”

Calling her statement “a lasting hope for our nation,” Father Pavone said: “Sandra’s work to overturn that devastating decision that was based on lies will not end with her death. When life ultimately triumphs over death, Sandra will share in that victory.”

Cano told the Catholic Register, “It’s a nightmare to be connected to a case that I never wanted to be connected to. Doe v. Bolton allows abortion up to the ninth month. This case takes children’s lives.”
